FDM printed part with surface texture added in SolidWorks 2020.

Printing 3D Texture on FDM 3D Printed Parts – it can be done!

While many examples exist of impressive texturing done on 3D printed Stratasys PolyJet printed parts (some wild examples are here), I have to admit it took me a while to learn that true texturing can also be added to Stratasys Fused Deposition Modeling (FDM) parts. This blog post will walk you through adding texture to all faces or some faces of a solid model, ready for FDM printing. You, too, may be surprised by the results.

I know that complex texturing is possible in a graphics sense with such software packages as Rhino, PhotoShop, Blender and more, but I’m going to show you what you can achieve simply by working with SolidWorks, from Rev. 2019 onwards, as an easy starting point. From there, you can follow the same basic steps but import your own texture files.

SolidWorks Texture Options

First off, let’s clarify some terms. Texture mapping has existed for years and strictly speaking creates a 2D “texture” or pattern. If I were to wrap that imagery around a 3D CAD model and print it on, say, a PolyJet multi-color 3D printer, I’d get a 3D part with a flat or perhaps curved surface decorated with a multi-color “picture” such as a map or a photo of leather. It could conform, but it’s still basically a decal.

A 3D texture instead is more properly referred to as Bump Mapping (not to be confused with …..too late….bit mapping). Bump mapping interprets the color/contrast information of a 2D image such that it renders light and shadow to give the illusion of a 3D part, while remaining in 2D. Taking this concept one step further, 3D CAD software such as SolidWorks can apply rules that convert white, black and grey shades into physical displacements, producing a kind of tessellated topology mapping. This new information can be saved as an STL file and generate a 3D printed part that has physical, tactile variations in material height across its surface. (For a detailed explanation and examples of texture versus bump-mapping, see the GrabCAD Tutorial “Adding Texture to 3D Models.”)

For FDM parts, you’ll get physical changes on the outer surface of the part that appear as your choice of say, a checkerboard, an arrangement of stars, a pebbly look or a series of waves. In the CAD software, you have a number of options for editing that bump map to produce bigger or smaller, higher or lower, finer or coarser variations of the original pattern, prior to saving the model file as an STL file.

Stepping through SolidWorks 3D Texturing

The key to making this option work in SolidWorks 3D CAD software (I’m using SolidWorks 2020), is in the Appearances tab. Here are the steps I’ve taken, highlighting the variety of choices you can make. My example is the Post-It Note holder I described in my PADT blog post about advanced infill options in GrabCAD Print.

  1. Open Post-It note CAD file, select Solid Bodies (left menu) and select Appearances (in the right toolbar).

  1. Expand Appearances and go all the way down to Miscellaneous, then click to open the 3D Textures folder.

Description automatically generated
  1. Scroll down to choose one of the more than 50 (currently) available patterns. Here, I’ve chosen a 5-pointed star pattern.
A screenshot of a computer

Description automatically generated
  1. I dragged and dropped that pattern onto the part body. A window opens up with several choices: the default is to apply the pattern to all faces:
A screenshot of a computer

Description automatically generated

However, you can mouse over within that pop-window to select only a single face, like this:

A screenshot of a computer

Description automatically generated
  1. When you’ve applied the pattern to either all faces or just one or two, you’ll see a new entry in the left window, Appearances, with the subheading: 5-pointed Star. Right-click on those words, and choose Edit Appearance:
A screenshot of a computer

Description automatically generated

Then the Appearances window expands as follows, opening by default to the Color/Image tab:

A screenshot of a computer

Description automatically generated

In this pane, if desired, you could even Browse to switch to a different pattern you have imported in a separate file.

  1. Click on Mapping, and you’ll see a number of “thumb wheel” sliders for resizing the pattern either via the wheel, clicking the up/down arrows, or just entering a value.

Mapping: this moves the pattern – you can see it march left or right, up or down. I used it to center the stars so there aren’t any half-stars cut off at the edge.

A screenshot of a computer

Description automatically generated

Size/Orientation: You can also try “Fit width to selection” or “Fit height to selection,” or experiment with height and width yourself, and even tilt the pattern at an angle. (If you don’t like the results, click on Reset Scale.) Here, I’ve worked with it to have two rows of five stars.

  1. Remember I said that you can also make the pattern higher or lower, like a change in elevation, so that it stands out a little or a lot. To make those choices, go to the Solid Bodies line in the Feature Manager tree, expand it, and click on the part name (mine is Champfer2).

In the fly-out window that appears, click on the third icon in the top row, “3D Texture.” This opens up an expanded window where you can refine the number of triangular facets that make up the shape of the selected texture pattern. In case you are working with more than one face and/or different patterns on each face, you would check the box under Texture Settings for each face when you want to edit it.

A screenshot of a computer

Description automatically generated

Here is where you can flip the pattern to extend outwards, or be recessed inwards, or, if you brought in a black/white 2D pattern in the first place, you can use this to convert it to a true 3D texture.

I’ll show you some variations of offset distance, refinement and element size, with exaggerated results, so you can see some of the possible effects:

A screenshot of a social media post

Description automatically generated

In this first example, the only change I made from the default was to increase the Texture Offset Distance from 0.010 to 0.200. The stars are extending out quite visibly.

Next, I changed Texture Refinement from 0% to 66.7%, and now you can see the stars more distinctly, with better defined edges:

A screenshot of a computer

Description automatically generated

Finally, I am going to change the Element size from 0.128 to 0.180in. It made the star edges only slightly sharper, though at the expense of increasing the number of facets from about 24,000 to 26,000; for large parts and highly detailed texturing, the increased file size could slow down slicing time.

  1. To make sure these textured areas print, you have to do one more special step: Convert to Mesh Body. Do this in the Feature Manager by right-clicking on the body, and selecting the second icon in the top row, “Convert to Mesh Body.” You can adjust some of these parameters, too, but I accepted the defaults.
A screenshot of a computer

Description automatically generated
  1. Lastly, Save the file in STL format, as usual.

At my company, PADT, my favorite FDM printer is our F370, so I’m going to set this up in GrabCAD Print software, to print there in ABS, at 0.005in layers:

A screenshot of a computer

Description automatically generated

You can definitely see the stars popping out on the front face; too bad you can also see two weird spikes part-way up, that are small bits of a partial row of stars. That means I should have split the face before I applied the texture, so that the upper portion was left plain. Well, next time.

Here’s the finished part, with its little spikes:

Description automatically generated

And here’s another example I did when I was first trying out a checkerboard pattern; I applied the texture to all faces, so it came out a bit interesting with the checkerboard on the top and bottom, too. Again, next time, I would be more selective to split up the model.

A picture containing table, sitting, wooden, luggage

Description automatically generated

NOTE: It’s clear that texturing works much better on vertical faces than horizontal, due to the nature of the FDM layering process – just be sure to orient your parts to allow for this.

For More Information on Texturing

SolidWorks offers a number of tutorials on the texturing set-up process, such as http://help.solidworks.com/2019/english/solidworks/sldworks/c_3d_textures.htm, and Shuvom Ghose at GrabCAD gives even more details about what to expect with this process in his post https://grabcad.com/tutorials/how-to-3d-texture-your-parts-for-fdm-printing-using-solidworks-2019

There will also be a general Stratasys webinar on The Benefits of 3D Printing Physical Textures on July 29 at 9am PT.

Commercial aircraft companies are already adding a pebble texture to flight-approved cosmetic FDM parts, such as covers for brackets and switches that keep them from being bumped. If you try this out, let us know what texture you chose and send us a photo of your part.

What a cool time to be involved in space-based projects, from the recent, stunningly successful manned Space X launch that linked up with the International Space Station (ISS), to the phase 1, unmanned Northrop Grumman/Lockheed Martin Artemis OmegA launch planned for a Spring 2021 debut. In between these big-splash projects are the launches of hundreds of small satellites, whether a 227 kg Starlink or a 1 kg CubeSat. (According to the Space Surveillance Network of the United States Space Force, there are more than 3,000 active satellites currently in orbit.)

One common thread that runs through many of these technology achievements is the use of 3D printed polymer parts, not just as manufacturing tools and fixtures but as flight-certified, end-use components. Applications already in use include:

– Enclosures, casings and covers for bus structures, avionics and electrical systems

– Mounting/routing brackets and clips for wire harnesses

– Barrier structures that separate different on-board experiments

The number and variety of these applications may surprise you, particularly as demonstrated with Stratasys fused deposition modeling (FDM) printed parts made from one of two currently selected materials: Ultem 9085 and Antero ESD (Antero 840CN03). (Tune in for the Stratasys webinar on this topic, Thursday, July 23, at 10am CDT, Additive Manufacturing Applications and Materials for Space.)

Tough, lightweight, space-ready materials

If ever an industry needed light-weight parts, it’s the space industry. Every kilogram loaded onto a rocket demands a physics-determined, expensive amount of fuel to create the thrust that will push it against Earth’s gravity. In addition, most components are one-of-a-kind or low volume. No wonder engineers have worked for decades to replace dense metals with effective, lighter weight polymers.

Those polymers must meet stringent requirement for mechanical behavior:

  • High strength-to-weight ratio
  • Heat resistant up to 320F/167C
  • Chemically resistant to various alcohols, solvents and oils
  • Flame-retardant
  • Non-outgassing

Add to this the need to work in a form that is compatible with additive manufacturing, and the number of material options goes down. However, there are two filaments that have made the grade.

Ultem 9085 is a polyetherimide (PEI) thermoplastic developed and marketed in raw form by SABIC. Stratasys uses strict quality control to convert it into filament that runs on its largest industrial printers and also offers a certified grade that includes detailed production test-data and traceable lot numbers.

Stratasys Ultem 9085 parts have been certified and flown on aircraft since 2011 and have been key components in spacecraft beginning in 2013, such as onboard the Northrop Grumman Antares vehicles typically used for resupplying the ISS.  An unusual project that has used Ultem 9085 parts is MIT/NASA Ames Research Center’s Synchronized Position Hold, Engage, Reorient, Experimental Satellites (SPHERES). Various iterations of these colorful nano-satellites (looking like volley-ball-sized dice) have floated inside the ISS since 2006, with an initial goal of testing the algorithms and sensors required to remotely control the rendezvous and docking in weightlessness of two or more satellite-type structures.

Since then many different versions have been built and delivered to the astronauts of the ISS; both high school and college students have been heavily involved in designing experiments that test physical and mechanical properties of materials in microgravity, such as wireless power transfer. In 2014, the “Slosh” project used Ultem 9085 parts to help connect the units to investigate the behavior of fluids such as fuel sloshing between containers.

More recently, in May 2020, Italian researchers at the National Institute for Nuclear Physics (INFN) relied on Ultem 9085 to build several final parts in its ultraviolet telescope that is now operating onboard the ISS. Called the Mini-EUSO (Extreme Universe Space Observatory), this piece of equipment is one element of a multi-component/multi-year study of terrestrial and cosmic UV emissions, and is now mounted in an earth-facing window of the ISS Russian Zvezda module.

Scientists involved in the Mini-EUSO noted that 3D printing saved them a lot of time in the development and manufacturing process of custom brackets that attach photo-multiplier detectors to the top and bottom of the focal surface, permitting modifications even “late” in the design process. Their use also saved several kilograms of upload mass.

Electrostatic Dissipative PEKK: Antero ESD

Although Ultem 9085 has proven extremely useful for many space-based applications, for certain applications even more capability is needed. The search was on for an electrostatic dissipative filament that also displayed great chemical, mechanical and flame/smoke/toxicity properties. NASA Goddard Spaceflight Center became the driving force behind Stratasys’ subsequent development of Antero ESD (Antero 840CN03), a filament based on the already successful Antero 800NA.

Both Antero products are based on polyetherketoneketone (PEKK), a high-strength, chemically resistant material; in addition, the ESD version is loaded with carbon-nanotube chopped fibers providing a moderately conductive “exit path” that naturally dissipates any charge build-up during normal operations. It also prevents powders, dust or fine particles from sticking to the surface.

NASA first flew Antero ESD parts in 2018 in the form of brackets holding fiber optic cables smoothly in place. This was inside the climate-change monitoring satellite called Ice, Cloud and land Elevation Satellite-2 (ICESat-2). The satellite was built and tested by then Northrop Grumman Innovation Systems, now part of Northrop Grumman Space Systems; the instrument itself is called the Advanced Topographic Laser Altimeter System (ATLAS), a space-based LIDAR unit. Built and managed by NASA Goddard Space Flight Center, this satellite monitors such data as changes in polar ice-sheet thickness.

Counting Down for Launch

An even bigger Antero ESD application – bigger in multiple ways – is waiting in the wings for its debut, comprising sections of the Orion module designed and built by Lockheed Martin Space Systems. This spacecraft will eventually carry astronauts to the Moon and beyond as part of NASA’s Artemis program, with the first un-crewed, lunar-orbit launch scheduled for Spring 2021.

The Orion craft’s docking hatch cover is made entirely from sections printed in Antero ESD. Six pie-shaped sub-sections with intricate curves and cut-outs fit together forming a one-meter diameter ring with a central hole. (If Ultem 9085 had been used, the parts would have needed a secondary coating or nickel-plating to deflect static charge, making the Antero ESD option very attractive.)

Ready, set, print, launch!

Sharing Nature While we Work From Home

The Winners From PADT’s 2020 Nature Photography Day Contest

Every month we try to do something fun at PADT, and before the evil spikey ball of death ruined everything we would usually do something food-related. Pi day = Pie. Chocolate Day = Chocolate. Anything = pizza. However, since most of us are working from home we could not all show up in the lunchroom at noon for team-building (chowing down).

So we have been looking at a few websites that list fun, often fake holidays, and found out that June 15th was “Nature Photography Day” After setting up some channels in Microsoft Teams we let everyone submit pictures. Then after a week of submitting, employees voted.

Some were downright stunning. All were beautiful.

We present the winners here for your viewing pleasure.

For those who are interested, here is how we did the contest:

  1. We created MS Teams channels for each of the categories we chose:
    Amature, Pro’ish, and Kids
  2. Within each category, there were five topics: Desert, Not Desert, Water, Plants & Flowers, Animals in Nature, Human Structures in Nature.
  3. Employees uploaded their images to the proper channel and shared a bit about each one.
  4. We used the emoticon capability in Teams to “vote” on each one. A heart was worth 3 points, a laughing face 2, and thumbs up 1.
  5. After the voting was done we added up the points for each category and that determined the winners.

Top Ten Additive Manufacturing Terms to Know

The world of additive manufacturing, or 3D printing, is constantly evolving. The technology was invented less than 35 years ago yet has come a long way. What began as a unique, though limited, way to develop low-end prototypes, has exploded into a critical component of the product development and manufacturing process with the ability to produce end-use parts for critical applications in markets such as industrial and aerospace and defense.

To help our customers and the larger technology community stay abreast of the changing world of additive manufacturing, we launched a glossary of the most important terms in the industry that you can bookmark here for easy access. To make it easier to digest, we’re also starting a blog series outlining ten terms to know in different sub-categories.

For our first post in the series, here are the top ten terms for Additive Manufacturing Processes that our experts think everyone should know:

Binder Jetting

Any additive manufacturing process that uses a binder to chemically bond powder where the binder is placed on the top layer of powder through small jets, usually using inkjet technology. One of the seven standard categories defined by ASTM International (www.ASTM.org) for additive manufacturing processes.

Digital Light Synthesis (DLS)

A type of vat photopolymerization additive manufacturing process where a projector under a transparent build plate shines ultraviolet light onto the build layer, which is against the transparent build plate. The part is then pulled upward so that a new layer of liquid fills between the build plate and the part, and the process is repeated. Digital light synthesis is a continuous build process that does not create distinct layers.

Direct Laser Melting (DLM) or Direct Metal Laser Sintering (DMLS)

A type of powder bed fusion additive manufacturing process where a laser beam is used to melt powder material. The beam is directed across the top layer of powder. The liquid material solidifies to create the desired part. A new layer of powder is placed on top, and the process is repeated. Also called laser powder bed fusion, metal powder bed fusion, or direct metal laser sintering.

Directed Energy Deposition (DED)

An additive manufacturing process where metal powder is jetted, or wire is extruded from a CNC controlled three or five-axis nozzle. The solid material is then melted by an energy source, usually a laser or electron beam, such that the liquid metal deposits onto the previous layers (or build plate) and then cools to a solid. One of the ASTM defined standard categories for additive manufacturing processes.

Fused Deposition Modeling (FDM)

A type of material extrusion additive manufacturing process where a continuous filament of thermoplastic material is fed into a heated extruder and deposited on the current build layer. It is the trademarked name used for systems manufactured by the process inventor, Stratasys. Fused filament fabrication is the generic term.

Laser Powder Bed Fusion (L-PBF)

A type of powder bed fusion additive manufacturing process where a laser is used to melt material on the top layer of a powder bed. Also called metal powder bed fusion or direct laser melting. Most often used to melt metal powder but is used with plastics as with selective laser sintering.

Laser Engineered Net Shaping (LENS)

A type of direct energy deposition additive manufacturing process where a powder is directed into a high-energy laser beam and melted before it is deposited on the build layer. Also called laser powder forming.

Material Jetting

Any additive manufacturing process where build or support material is jetted through multiple small nozzles whose position is computer controlled to lay down material to create a layer. One of the ASTM defined standard categories for additive manufacturing processes.

Stereolithography Apparatus (SLA)

A type of vat photopolymerization additive manufacturing where a laser is used to draw a path on the current layer, converting the liquid polymer into a solid. Stereolithography was the first commercially available additive manufacturing process.

Vat Polymerization

A class of additive manufacturing processes that utilizes the hardening of a photopolymer with ultraviolet light. A vat of liquid is filled with liquid photopolymer resin, and ultraviolet light is either traced on the build surface or projected on it. Stereolithography is the most common form of vat photopolymerization. The build layer can be on the top of the vat of liquid or the bottom. One of the ASTM defined standard categories for additive manufacturing processes.

We hope this new blog series will help to firm up your knowledge of the ever-evolving world of additive manufacturing.
