Additively Manufactured: Best Practices for Composite Tooling with 3D Printing

The advanced composites industry has a continual need for innovative tooling solutions. Conventional tooling is typically heavy, costly and time-consuming to produce. New applications, product improvements and the demand for faster, lower-cost tool creation challenge composite product manufacturers to innovate and remain competitive.

The use of additive manufacturing (or “3D printing”), and specifically FDM, for composite tooling has demonstrated considerable cost and lead time reductions while providing numerous other advantages such as immense design freedom and rapid iteration, nearly regardless of part complexity.

Download the white paper to learn more about the various advantages and capabilities of composite tooling with additive over traditional manufacturing methods, and discover the best practices for ensuring that your composite tooling process is efficient as possible.

This document includes best practices for:

  • Testing and characterization
  • Tool Design, Production, & Use
  • Analyzing results

Introduction to Additive Manufacturing for Composites

Additive manufacturing encompasses methods of fabrication that build objects through the successive addition of material, as opposed to subtractive methods such as CNC machining, that remove material until a final shape is achieved. Composite fabrication is one of the most original forms of additive manufacturing.

Whether the process involves wet lay-up, hand lay-up of prepreg materials, or automated fiber placement (AFP), methods of composite manufacture are distinctly additive in nature, building up to final part forms typically one layer at a time. However, the nature of additive manufacturing has been revolutionized with the advent of the 3D printing industry.

Strong, resilient, fiber-reinforced thermoplastics. Lightweight, low-cost composite tooling. Explore these and other characteristics and benefits of additively manufactured composites in the e-book “Introduction to Additive Manufacturing for Composites.”

This e-book covers:

  • Current applications for composite fabrications
  • Comparison of printed and conventional tooling
  • Characteristics of printed mold tooling

 

Exploring RAPID 2018 in Fort Worth, TX

Waking up at 3 A.M. isn’t something I like to do often. However, for this conference I was about to attend, it was worth the early rise! Caffeine is a must to get through a long day of walking around and being educated by all the different new and old manufacturers of 3D printers. If you have been around 3D printing, you know there are really two conferences that are above the rest; AMUG and RAPID. Here are some of the things that were announced that I believe are the most significant at RAPID.

Stratasys:

Stratasys didn’t disappoint this year in introducing a new carbon fiber 3D printer, material, and metal technology that will be coming in a year+. We are very familiar with the Nylon 12 Carbon Fiber reinforced material that Stratasys has. It is THE best Nylon 12 carbon fiber material on the market and there are a few factors as to why that is the case. One is that they are using longer strands of Carbon Fiber than the competitor along with 35% carbon fiber filled parts compared to 15%. Soluble support is huge for this material as well, along with 2 to 5 times faster printer speeds. Check out how One Wheel is using this printer to help with manufacturing their cool skateboard:

ANTERO 800 is the new material that Stratasys released recently. This material is being used in many amazing ways. Lockheed Martin/NASA/Stratasys/PADT collaborated in a very successful task to get flight approved hardware for one of the next missions to space. Below is the full story on this new and exciting ESD version of Antero 800 FDM material. Could your company also benefit from using this type of material? We would like to help!

http://www.3ders.org/articles/20180418-lockheed-martin-padt-stratasys-to-3d-print-over-100-parts-for-nasas-orion-capsule.html

Vero Magenta V and Vero Yellow V are the new Polyjet materials to help with getting more vibrant colors along with deeper red and brighter yellow. 500,000 color combinations can be achieved now with these 2 materials that have been improved upon. Absolutely beautiful parts can be made with a Stratasys J750 or J735.

Metal We have been asking (and have been asked) for metal for the longest time! When is Stratasys going to jump into the metal game? One of the main reasons why I went to RAPID this year was to see Stratasys Metal parts. They did not disappoint. As far as what density these metal parts are, the process for printing, and when a machine will be available, that is still the big unknown. One thing mentioned at the conference is that they are wanting to make metal 3D printing affordable to all with the ability to 3D print metal 80% cheaper than anything available right now. How this compares to what Desktop Metal, Mark Forged, HP, and others who proclaim to make metal parts cheaper than the Laser or Electron Beam options is yet to be known. Stratasys wants to be able to provide value to the metal market by focusing on areas that are lacking, which is Aluminum. Always good to have competition against the large companies of metal as it makes everyone get better at what they are doing. Read more about this machine and what Phil Reeves (VP of Strategic Consulting from Stratasys) has to say in an exclusive interview with TCT. Also below are a few pictures I took in the Stratasys booth of their metal parts that were on display.

Software was featured big time at RAPID because it unlocks the ability to 3D print amazing parts like this that was featured in the EOS booth. Lattice structures and topology optimized parts!

There were a lot of companies present at RAPID that highlighted where the industry is headed. Materials with vibrant color capabilities was one such area receiving a lot of attention. While competitors have introduced machines that are capable of printing in a wide variety of colors, they still fall short when compared to the Stratasys Polyjet offerings. Machines such as the J750 and J735 both offer a similar range of color compared to other companies on the market, but surpass them when it comes to material options, applications, and overall usability.

I enjoyed talking with all the major 3D printer manufactures at RAPID. One questions I would ask each of them is, what makes your system better than the competitors? I loved hearing the sales pitch about their machines and there was some great insight gained by asking this.At the end of the day, it all comes down to how you are wanting to use the 3D printer. At PADT we have many different 3D printers, and while we see and understand the appeal of the various different offerings on the market today, there is a reason why we continue to resell and support the brands we do. Let us know how we can help you out and any questions that you have with 3D printing.

Press Release:

Mission to the Moon: Stratasys Joins Forces with Lockheed Martin and PADT to Engineer Advanced 3D Printed Parts For NASA’s Orion Mission

Stratasys 3D printers and materials provide extremely high levels of strength, durability and thermal properties to power missions to deep space

Variant of new Stratasys Antero™ 800NA, PEKK-based material offers electro-static dissipative (ESD) functionality for advanced mechanical, chemical, and thermal properties

Minneapolis, MN & Rehovot, Israel and TEMPE, AZ., April 17, 2018 – Stratasys Ltd. (NASDAQ: SSYS), a global leader in applied additive technology solutions, and Phoenix Analysis & Design Technologies, Inc. (PADT) jointly announced the companies are teaming with Lockheed Martin Space to deliver next-generation 3D printed parts for NASA’s Orion deep-space spacecraft. Key to the project are Stratasys advanced materials – including an ESD variant of the new Antero™ 800NA, a PEKK-based thermoplastic offering high performance mechanical, chemical, and thermal properties.

The Orion spacecraft leverages a variant of new Stratasys Antero 800NA to build an intricately-connected 3D printed docking hatch door

Orion is NASA’s spacecraft that will send astronauts to the Moon and beyond. Orion’s next test flight, dubbed Exploration Mission-1 (EM-1), will be the first integration mission with the world’s most powerful rocket, the Space Launch System, where an un-crewed Orion will fly thousands of miles beyond the Moon during an approximately three week mission.

The following flight, EM-2, will also go near the Moon, but with astronauts on-board, a first since 1972 and will enable NASA to prepare for increasingly complex missions in deep space. The mission will use more than 100 3D printed production parts on board – engineered in conjunction with Lockheed Martin, Stratasys and PADT.

The production-grade, thermoplastic 3D printed parts on NASA’s Orion vehicle are produced at the Additive Manufacturing Lab at Lockheed Martin in conjunction with PADT, which now includes the latest in Stratasys 3D printers and materials. Using advanced materials such as ULTEM 9085 and the new Antero material incorporating critical electro-static dissipative (ESD) functionality – NASA could meet key requirements for 3D printed parts to perform in the extremes of deep space. Antero is ideally suited to meet NASA’s requirements for heat and chemical resistance, along with the ability to withstand high mechanical loads.

“Working with PADT, Stratasys, and NASA has enabled us to achieve highly consistent builds that move beyond the realm of prototyping and into production,” said Brian Kaplun, Manager of Additive Manufacturing at Lockheed Martin Space. “We’re not just creating parts, we’re reshaping our production strategy to make spacecraft more affordable and faster to produce.”

Lockheed Martin is one of the first customers leveraging Stratasys’ Antero material – a PEKK-based thermoplastic with advanced mechanical, chemical and thermal properties.

The Lockheed Martin, Stratasys and PADT-engineered collaboration is differentiated by an ability to create consistency and repeatability in mass scale across the entire additive manufacturing part production process. Lockheed Martin is also one of the first customers leveraging Stratasys’ Antero, using the new thermoplastic for a critical part situated just outside of Orion’s docking hatch. The complex part consists of six individual 3D printed components locked together to form a ring on the craft’s exterior. The part is currently on display in the Lockheed Martin booth #603 at the 34th Space Symposium in Colorado Springs, CO April 16-19.

“The demands of space travel require extremely high performance materials and the most rigorous manufacturing processes in the industry. Part integrity and repeatability are essential and must pass NASA’s demanding testing and validation process,” said Scott Sevcik, Vice President of Manufacturing at Stratasys. “Based on decades of experience delivering strong and lightweight additive manufacturing solutions for leaders across the aerospace industry, Stratasys technology is ideally suited to match the high-reliability manufacturing processes required for production parts in space exploration.”

“It’s exciting to be a part of the Orion mission and Lockheed Martin’s efforts to transition additive manufacturing from prototyping to production,” said Rey Chu, Principal and Co-Owner at PADT. “Additive manufacturing technology and materials have come a long way to become a full-fledged end-use manufacturing option.”

Exploring the Value of Multi-Print 3D Models for Medical with Stratasys & Intermountain Healthcare

PADT’s Salt Lake City office has been involved with fulfillment of medical 3d Printing of several cases where customers are exploring the value of multi-color and multi-material medical 3D models by using the Stratasys J750 or the Connex 3. One of those cases was presented at the Mayo Clinic’s Collaborative 3D Printing in Medical Practice 2018 course, which was held in Arizona this year.

An Intermountain Healthcare facility in Salt Lake City needed help with 3D printing a patient-specific anatomy, as they were looking to better their understanding of the value of 3D printing using multi-color printer beyond their existing in-house capabilities. In the picture below, Rami Shorti, PhD., a senior Biomechanical Engineering Scientist at Intermountain Healthcare, wrote:

“A patient with a horseshoe kidney and multiple large symptomatic stones, who had failed Extracorporeal Shock Wave Lithotripsy and Ureteroscopy Treatment, was used to evaluate the benefit of using different imaging modalities intraoperatively.” 

Working with us in Salt Lake City, Rami Shorti, PhD, prepared the patient-specific medical imaging segmentation, post-processing of the patient anatomy, and finally generated for us a 3D printable CAD model that we were able to print using a Stratasys Objet 260 Connex 3. Since our office is located just around the corner from the hospital, we were able to work closely with Rami to identify the colors and finish of the final part.

The Connex 3 printer was introduced in 2014 as the only printer in the world that could combine three different model materials in a single print pass. Most 3D printers can only print with one material at a time, which is one of the main reasons why this technology is preferred for medical use cases along with its added precision. In 2017, Stratasys introduced the J750, which again is an industry first, becoming the only printer in the world that can print 6 different materials at the same time.  Combinations of hard plastics and rubber materials allow for a range of shore hardness values along with the ability to mix three primary colors to print 500,000 different colors.

With a quick turnaround needed, we decided to use the Connex 3 and were amazed that we were able to print the parts in two batches. Within 48 hours of receiving the STL files from Dr. Shorti, we were able to 3D print, post-process, and deliver the parts in time for the surgeon to review the time-sensitive surgical planning guides using the mockup. To enhance the transparency of the parts, we simply applied a few coats of Rust-Oleum Clear Gloss to the 3D printed part.  Now we were able to relax and wait for it to dry.  Below is a picture of the finished products displayed at the Mayo Clinic event.

 “3D printing added a level of benefit because of its ability to showcase the stones, renal pelvis, and renal arteries and veins simultaneously through the image fusion step done in Mimics software and with the use of specific materials and contrasting colors.  In addition, its ability to be held and manipulated in space was observed to be beneficial especially for patient education.”

– Rami Shorti, PhD., senior Biomechanical Engineering Scientist, Intermountain Healthcare

PADT is excited to continue our work with Intermountain Healthcare, and grow this relationship as new opportunities arise to leverage multi-material printing.

Stratasys Partner Kickoff 2018 in Miami

My first time to Miami was a success! Last year, Stratasys held the partner kickoff in New Orleans and that was when they launched the F1, 2, and 3 series. Since then they have sold over 800 units of these types of FDM 3D printers in the USA. This year in Miami, they did announce something new but it still has a few quarters to go until there is an official release. To say I am excited about what is coming is an understatement! In fact, Stratasys is going to be releasing one new printer here in a few weeks. I am excited for the direction they are going. During this partner kickoff, they mentioned a huge price drop on all of their Polyjet printers! Send us a message for the latest pricing at sales@padtinc.com.

As for PADT employees that were in attendance, we had quite the representation this year. Rey Chu (Co-Owner of PADT), Mario Vargas (Manager of Hardware Sales), Norman Stucker (Colorado Territory Manager), Anthony Wagoner (Utah Territory Manager), Kathryn Pesta (Sales Operations Manager), and me (James Barker, Sr. Application Engineer).

Pictured above from left to right is Mario Vargas, Kathryn Pesta, James Barker, and Anthony Wagoner.

Above is a picture of the Stratasys Panel that was open to some Q&A. 2nd from the right is S. Scott Crump who is the inventor of FDM (fused deposition modeling) printers 30 years ago. Below is a picture of the anniversary info for Stratasys along with Objet (Polyjet technology 20 years) and the merger between the two companies is now 5 years old!

My introduction to 3D printers started 8 years ago with an Objet Eden 500 printer at L-3 Communications where I ran their 3D print lab. 6 months later we got an additional Polyjet printer which was a Connex 500. Amazing that we were able to justify purchasing another high quality machine after a few months of operating the Objet Eden 500! A few years later we got our first Uprint FDM printer from a sister company that no longer had a need for it. After using the Uprint for a few months, I was made aware of some of these thermoplastic materials that could only be printed on the production grade FDM machines. I created a business case to get the Fortus 450 and had every material option available at that time to print with (ABS family of materials, ASA, PC, Nylon 12, Ultem 9085, and Ultem 1010). I love both of these technologies and am confident that they provide the best solution for either rapid prototyping or tooling applications. We even have many customers that are printing production parts with these very precise 3D printers.

One customer that is printing production quality parts is Laika Studios, who has produced these movies: Kubo and the Two Strings, The Boxtrolls, ParaNorman, and Coraline. The presentation they made for us on their stop motion animation was so much fun! 10 years ago for Nightmare before Christmas there were 800+ hand sculpted faces made. For Kubo and the Two Strings, there were 64,000 facial expressions that were all 3d printed with a Stratasys J750. Another fun fact about the movie is that it took 60 hours of 3D printing for one second of film time to be created which is why it takes 2-3 years to complete a film. Moonbeast is a 3ft long puppet that is entirely comprised of 3d printed parts which is the largest character they have done to date. If you have watched Kubo and the Two Strings, it appears to be computer animated but in reality it is stop animation with 3D printed parts! Here is a fun short video (13 seconds) of what the Stratasys printer looks like as it is printing and then support material being removed from the head with different facial expressions.

Matt Gimble, who works for Penske as a Production Manager, shared with us many of the different applications that have helped them save a lot of money since they’ve incorporated 3D printing. Racing is rapidly evolving and is very technical nowadays with a huge emphasis on engineering. 3D printing gives them the tools to meet the new challenges. There are many different great uses they’ve had for 3D printing – from a redesigned rear gear pump design, to a new exhaust tailpipe. Even production parts are made with Stratasys’ newest material, Nylon 12CF. This is a high strength chopped carbon fiber filled Nylon 12. Many that use this material are awe-inspired with its performance! The Superspeedway side view mirror is made out of this material and saved Team Penske 4-6 weeks – which is how long it takes for the mold to be made. Then what if the mold needs altering? Crew Helmet Light/Camera mount is also made in this great thermoplastic/composite material called Nylon 12CF.

The above Fuel Probe was re-engineered and is lighter than its predecessor, plus more ergonomical to help with delivering fuel in a timely manner. Pre-preg carbon fiber sleeves when wrapped around a soluble support material and after the autoclave heating process, the soluble core is dissolved in a sodium hydroxide cleaning tank leaving only the carbon fiber. PADT is a manufacturer for the cleaning tanks that are sold with any Stratasys FDM 3d printer. The core is made out of ST-130 material which is perfect for this application or sacrificial tooling. Ultem 1010 was used as well to create carbon fiber layup tools in a fraction of the time it would have taken for the steel molds to be made. Typical turnaround is 1-3 days, as compared to 4-6 weeks. These are all great applications by Team Penske! Well done!!

We learned a lot at the partner kickoff. Luckily I was able to get this great picture with S. Scott Crump and Mario Vargas! To this day Scott is still inventing and is a major contributor to innovating at Stratasys. While talking with him and Mario, he started talking about these many adventures that he goes on. Scuba diving off the island of Tortuga and having many sharks swimming above isn’t for the faint of heart, yet it is where Scott seems to find his happy place. 

My wife flew out Thursday night to come see Miami with me. It was my first time visiting Florida and we had a phenomenal time there. We put 800 miles on the rental car driving all around. Driving down the Florida Keys all the way to Key West was a blast and if you ever go to Key West, make sure to get a Cuban sandwich from the restaurant Bien! It is MUY MUY BIEN! The islands are so beautiful! We also went to the Everglades where we got an airboat tour and where I even held a 4 year old Alligator and gave it a kiss on the back of its head. My little girls shriek every time they see the picture!

We had a great time in Florida! As we now look to the future, watch out for some exciting updates about new products that are coming! Stratasys, in my opinion, is going to continue being a leader in the Additive Manufacturing realm and I can’t wait to help announce some of the new equipment once it is available!
Any questions you have, you can direct them to me at James.barker@padtinc.com. Thanks!

Standard Roof Rack Fairing Mount Getting In Your Way?! Engineer it better and 3D Print it!

It is no mystery that I love my Subaru. I bought it with the intention of using it and I have continually made modifications with a focus on functionality.

When I bought my roof crossbars in order to mount ski and/or bike racks, I quickly realized I needed to get a fairing in order to reduce drag and wind noise. The fairing functions as designed, and looks great as well. However, when I went to install my bike rack, I noticed that the fairing mount was in the way of mounting at the tower. As a result, I had to mount the rack inboard of the tower by a few inches. This mounting position had a few negative results:

  • The bike was slightly harder to load/unload
  • The additional distance from the tower resulted in additional crossbar flex and bike movement
  • Additional interference between bikes when two racks are installed

These issues could all be solved if the fairing mount was simply inboard a few more inches. If only I had access to the resources to make such a concept a reality…. oh wait, PADT has all the capabilities needed to take this from concept to reality, what a happy coincidence!

First, we used our in-house ZEISS Comet L3D scanner to get a digital version of the standard left fairing mount bracket. The original bracket is coated with Talcum powder to aid in the scanning process.

The output from the scanning software is a faceted model in *.STL format. I imported this faceted CAD into ANSYS SpaceClaim in order to use it as a template to create editable CAD geometry to use as a basis to create my revised design. The standard mounting bracket is an injection molded part and is hollow with the exception of a couple of ribs. I made sure to capture all this geometry to carry forward into my redesigned parts, which would make the move to scaled manufacturing of this design easy.

Continuing in ANSYS SpaceClaim, as it is a direct modeling software instead of traditional feature-based modeling, I was able to split the bracket’s two function ends, the crossbar end and fairing end, and offset them by 4.5 inches, in order to allow the bike rack to mount right at the crossbar tower. I used the geometry from the center section CAD to create my offset structure. A mirrored version allows both the driver and passenger side fairing mount to be moved inboard to enable mounting of two bike racks in optimal positions. The next step is to turn my CAD geometry back into faceted *.STL format for printing, which can be done directly within ANSYS SpaceClaim.

 

After the design has been completed, I spoke with our 3D printing group to discuss what technology and material would be good for these brackets, as the parts will be installed on the car during the Colorado summer and winter. For this application, we decided on our in-house Selective Laser Sintering (SLS) SINTERSTATION 2500 PLUS and glass filled nylon material. As this process uses a powder bed when building the parts, no support is needed for overhanging geometry, so the part can be built fully featured. Find out more about the 3D printing technologies available at PADT here.

Finally, it was time to see the results. The new fairing mount offset brackets installed just like the factory pieces, but allowed the installation of the bike rack right at the tower, reducing the movement that was present when mounted inboard, as well as making it easier to load and unload bikes!!

I am very happy with the end result. The new parts assembled perfectly, just as the factory pieces did, and I have increased the functionality of my vehicle yet again. Stay tuned for some additional work featuring these brackets, and I’m sure the next thing I find that can be engineered better! You can find the files on GrabCAD here.

 

How to Simplify Aircraft Certification – Stratasys Webinar

The aerospace industry’s adoption of additive manufacturing is growing and predicted to revolutionize the manufacturing process. However, to meet stringent FAA and EASA requirements, AM-developed aerospace products must be certified that they can achieve the robust performance levels provided by traditional manufacturing methods. Current certification processes are complex and variable, and thus obstruct AM adoption in aerospace.

Thanks to a newly released aerospace package released by Stratasys for their Fortus 900mc printer and ULTEM 9085 resin, Aerospace Organizations are now able to simplify the aviation certification process for their manufactured parts.

Join PADT’s 3D Printing General Manager, Norman Stucker for a live webinar that will introduce you to the new Stratasys aerospace package that removes the complexity from FAA and EASA certification.

By attending this webinar, you will learn:

  • How Stratasys can help get more parts certified for flight quicker and easier.

Quick Tips for Stratasys’ new Nylon 12CF Material

One of the newest materials available for the Stratasys Fortus 450 users (other machines could have this capability at a later date) is the Nylon 12CF. Nylon 12CF is a Carbon Fiber filled Nylon 12 filament thermoplastic. The carbon fiber is chopped fibers that are 150 microns long. This is Stratasys’ highest strength and stiffness to weight ratio for any of their materials to date as shown below. 
Often times, when Stratasys is getting close to releasing a new material, they will allow certain users to be a beta test site. One beta user was Ashley Guy who is the owner of Utah Trikes, which is located in Payson, Utah. He is having so much success with this material that he is making production parts with it. Watch this video to hear more from Ashley and to see some of his 3D printed parts.

Talking with Ashley, he has helped us with understanding some of the tips and tricks to get better results from printing with this material. One change that he highly recommends is to adjust the air gap between raster’s to -.004”. This will force more material between the raster’s so there won’t be as many noticeable air gaps. Here is a visual representation of the air gap difference using Stratasys software Insight:

The end goal at Utah Trikes is to produce production parts with this material, so by adjusting the air gap, the appearance of the parts look close to injection mold quality after the parts have been run through a tumbler. Some key things that I really like about this material is that the support material is soluble and easily removed using PADT’s own support cleaning apparatus (SCA Tank) that aid with the support removal. After the support has been removed, they are placed in a tumbling machine to smooth the surfaces of the part with different media within the tumbling machine. Any post process drilling or installing of helicoil inserts or adding bushings to the part is done manually.

Jerry Feldmiller of Orbital ATK, who also did a beta test of this material at his site in Chandler, Arizona, mentions these 3 tips:

  1. Nylon12 CF defaults to “Use model material for Support”. 90% of the time I uncheck this option.
  2. I use stabilizing walls and large thin parts to anchor the part to the build sheet and prevent peal up.
  3. Use seam control set to Align to Nearest.

Jerry also supplied his Nylon 12CF Tensile Test that he performed for this new material as shown below. He mentions that the Tensile Strength is 8-15 ksi depending on X-Y orientation.
~5 ksi in Z-axis, slightly lower than expected.

This part is used to clamp a rubber tube which replace the old ball valve design at ATK. Ball valves are easily contaminated and have to be replaced. After two design iterations, the tool is functioning.

Jerry also follows a guide that Stratasys offers for running this material. If you would like a copy of this guide, please email me your info and I will send it to you. My email is James.barker@padtinc.com

Now onto Stratasys and the pointers that they have for this material. First, make sure the orientation of the part is built in its strongest orientation. Nylon materials have the best layer-to-layer bond when comparing them against the other thermoplastics that Stratasys offers.

Whenever you print with the Nylon materials (Nylon 6, 12, and 12CF), it is advised to print the sacrificial tower so that any loose strands of material are collected in the sacrificial tower instead of being seen on the 3D printed part. You also want to make sure that these materials are all stored in a cool and dry area. Moisture is the filaments worst enemy, so by storing the material properly, this will help tremendously with quality builds.

It is also recommended for parts larger than 3 inches in height to swap the support material for model material when possible. Since the support material has a different shrink factor than the model material, it is advised to print with model material where permitted. This will also speed your build time up as the machine will not have to switch back and forth between model and support material. We have seen some customers shave 5+ hours off 20 hour builds by doing this.

This best practice paper is the quick tips and tricks for this Nylon 12CF material from our users of this material. The Stratasys guide goes into a little more detail on other recommendations when printing with this material that I would like to email to you. Please email me with your info.

Let us know if this material is of interest to you and if you would like us to print a sample part for testing purposes.

Getting to Know PADT: Support Cleaning Apparatus (SCA) Manufacturing and Support

This is the third installment in our review of all the different products and services PADT offers our customers. As we add more, they will be available here.  As always, if you have any questions don’t hesitate to reach out to info@padtinc.com or give us a call at 1-800-293-PADT.

PADT is in the business of helping people who make products.  So most people think of us as a provider of tools and services.  What they do not know is that PADT actually has a few of its own products.  The most successful of these is our line of Support Cleaning Apparatus systems, abbreviated as SCA.  These devices are used to remove soluble support material from parts 3D printed in Stratasys Fused Deposition Modeling Systems. They are robust machines manufactured and serviced by PADT, but sold through the Stratasys worldwide sales channel. As of July of 2017, over 10,800 units have been delivered to Stratasys.

Optimized Performance for Hands-Off Part Cleaning

The Stratasys 3D Printing systems that use Fused Deposition Modeling extrude plastic through a heated nozzle to build parts one layer at a time.  There are actually two nozzles. One puts down the building material and the other a support material that is dissolved in warm water that is slightly base.  The best way to remove that support material is to put it into a warm bath where the part is gently tumbled so that the water can works its way evenly into the part.  Stratasys tried several solutions for a companion washing system and eventually came to PADT and asked if we would try our hand at building a robust and efficient system.

The result was the SCA-1200.  Launched at the end of 2008 it met the design requirements for reliability, part cleaning time, and noise.  Over 7,000 of these systems were shipped and saw heavy usage. In fact, if you have a Stratasys FDM system there is a good chance you have an SCA-1200.  It contained a unique shower head design that was optimized with simulation, and a modular assembly that could be repaired easily in the field.

Based upon the success and lessons learned from the SCA-1200, we released the SCA-1200HT in 2014.  With the same basic form factor, this design replaced the off-the-shelf magnetically coupled pump with a simpler and more reliable custom design from PADT. The new unit also had a more pleasing visual design, several usability enhancements, and a greater temperature range. It has sold over 3,000 units and continues to be a popular system.  The latest release includes a no-temperature setting that allows it to be used to clean Stratasys Polyjet parts.

The success of both system lead to a request to look at building a larger machine that could clean more parts at one time as well as larger parts.  The SCA 3600 has three times the volume but shares many internal parts with the SCA-1200HT.  Both of the new systems are doing well in the field with even better reliability and faster part cleaning times. They are also simpler to debug and repair.

The SCA systems are sold as stand alone devices or are bundled with key Stratasys FDM machines.  You can learn more about them on our SCA page:  www.padtinc.com/sca or you can contact whoever you buy your Stratasys equipment from.

Here is a video for the SCA-1200HT that talks all about what it does:

Practicing what We Preach

One of the most rewarding aspects of designing and manufacturing the SCA family of products was that it forced us to practice what we preach. We talk to companies every day about using simulation, 3D Printing, design for manufacturing, proper product development processes, and many more things needed to get a product right.  With the SCA we were the customer. We had to Walk the Walk or stop talking the talk.

 

It has been a phenomenal experience that has made us even better at helping our customers produce their new products. We used CFD to optimize the gentle agitation design and shower head and worked closely with our vendors to minimize the cost of manufacturing.  The worst part was that when the schedule slipped, we couldn’t blame the customer (only slightly joking).  One of the best set of lessons came from doing the repair and refurbishment of systems that failed. Even though the failure rate was low, we learned a lot and were able to make improvements to future designs. Now when we sit across from a customer and talk about the design, test, and manufacture of their product, we can really say that we understand where they are coming from.
