Getting to Know PADT: 3D Printing Services

 This post is the thirteenth 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.

If there is one service that most people connect PADT with it is our 3D Printing Services.  We have been making prototypes for companies using this ever-advancing technology since we started the company in 1994. As 3D Printing has become more popular and entered the mainstream even beyond engineering, what 3D Printing means to people has changed as well. Along with that, people’s understanding of exactly what it is we do in this area has drifted a little from what goes on. In this month’s installment of our “Getting to Know PADT” series, we will work to provide insight into what 3D Printing Services are and how they can benefit your company.

What is “3D Printing” and “3D Printing Services?”

To start, it should be called “Additive and Advanced Manufacturing and Prototyping Services, ” but people search for “3D Printing” so that is what we call it.  3D Printing is the common name for what is technically referred to as Additive Manufacturing, or AM.  Most physical parts are made (manufactured) by casting or shaping material into a shape you want, removing material from stock to get the shapes you want, and/or combining physical parts you get by the other two methods. Instead of these well-proven methods, AM creates a part by building up material one layer at a time.  That is why it is called additive – it adds layers of material to get a shape. Here is an older blog article showing the most common technologies used in AM.

The advantage of this approach is that you just need one machine to make a part, you can go straight from a computer model to that part, and you are not held back by the physical constraints of traditional processes. These features allow anyone to make a part and to make shapes we just could not create before.  At first, we only used it for prototypes before parts were made. Then we started to make tools to make final products, and now 3D Printing is employed to manufacturing end-use parts.

In the world of mechanical engineering, where 3D Printing is heavily used, we call companies that use additive manufacturing to make parts for other 3D Printing Service Bureaus or 3D Printing Service Providers. Therefore, the full process of doing manufacturing using the technology is called: 3D Printing Services.

The critical word in that last sentence is “full.”  Sending a computer model to a 3D Printer is just one of many steps involved in Additive Manufacturing.  When the service is employed correctly, it includes identifying the right type of additive manufacturing to use, preparing the geometry, setting parameters on the machine, printing the parts, removing supports, cleaning the parts, sanding, applying a surface finish treatment, and then inspection and shipping.  Anyone can send a part to a printer; the other steps are what make the difference between simply printing a part, and producing a great part.

What Services does PADT Offer?

Additive Manufacturing covers a wide range of technologies that create parts one layer at a time, using a variety of approaches. Some extrude, some harden, some use an inkjet print head, and still others melt material.  What they have in common is creating solid geometry one layer at a time. Each technology has its own unique set of advantages, and that is why PADT offers so many different 3D Printing technologies for our customers.  Each of these approaches has unique part preparations, machine parameters, and post-printing processes. Each with a unique set of advantages.  The key to success is knowing which technology is best for each part and then executing it correctly.

Currently, PADT’s 3D Printing Services Group makes parts for customers using the following technologies.  Each one listed has a brief description of its advantages.  See our website for more details.

As a proud reseller for Stratasys systems, we feel strongly that the two primary technologies from Stratasys, FDM, and Polyjet, are the best for customers who want to do Additive Manufacturing in-house or as a service provider. When customers need something different, they can come to PADT to take advantage of the unique capabilities found in each technology.

How is 3D Printing with PADT Better?

The difference is in what we know and how to execute the complete process.  As a provider of 3D Printing services for over 23 years, very few people in the industry even come close to the amount of experience that we bring to the table.  We also know product development and traditional manufacturing, so when a customer comes to us with a need, we understand what they are asking to do and why. That helps us make the right recommendation on process, material, and post-processing.

A few differentiators are:

  • We know our machines
  • We know our materials
  • We offer a wide range of plastic and metal materials
  • We understand post-processing
  • We understand support removal (we manufacture the leading support removal system)
  • We understand design and manufacturing
  • In-house machining, painting, and part finishing
  • In-house inspection and quality
  • Employees who are enthusiastic and dedicated to providing the right solution.

We are also always looking at the latest technologies and adding what our customers need. 

Next Steps and Where to Learn More

The very best way to learn more about PADT’s 3D Printing services is to have us print a part. The full experience and the final product will explain why, with so many choices, so many companies large and small count on us for their Additive Manufacturing.
