We get this one a lot so it was finally time to address it! One of the most common things that people say is that our process is just marketing and that anyone could print our product at home on their own off-the-shelf 3D printer. So let’s talk!

This is part one of three of why Pellet Extrusion Matters. — Material Selection.

The first point that I wanted to drive home with this video was basic material selection. The number of material grades that are available for purchase as pellets is dramatically higher than the filament supply chain.

And that’s for a reason! Each of those different grades of polymer is tailored for certain use cases - whether it be chemical resistance, strength, or even thermals. With such a limited selection under the umbrella of the Filament Supply Chain, it makes sense that you can’t get everything you need, especially for a uniquely high stress application like ours.

In the next video we will talk more about the chemistry of the polymer and why we chose it, and then the final video will close with how we process it, from compounding to final melt.

Found a great opportunity on the trail to illustrate how our modular MK3 design actually works.

The whole intent is that these can grow with your build.

If you upgrade to shocks with a longer compressed length, you can add our screw in spacers to adjust the hard stop height. Or if you’re tweaking tire fitment, you can adjust travel to get it perfect.

If you increase your vehicle weight, we have optional stiffness inserts that sit inside the compression stack to increase the total stiffness, allowing you to make them as stiff, or soft as you want.

On top of all of that, these carry the most air damping of any product we’ve built - ever. And our best warranty yet. 8 years, no questions asked.

The brand new PerryParts MK3 bump stops!

So grateful for the opportunity to speak at Dartmouth’s Thayer school of engineering about 3D printing.
This is a few excerpts of our talk called “Material Matters” — an in depth case study of combining material selection with process, design, and automation, to build a cohesive manufacturing system.
In this reel I’m specifically highlighting some of the deficiencies of filament, we went more in depth into how we overcame those hurdles later in the talk.
This was such a cool experience speaking to a bunch of young engineers - they asked a lot of great questions. It was a ton of fun.

Meet MK3.
Hundreds of iterations.
Millions of cycles.
Everything our customers have asked us for, and more.
MK3 the culmination of four years of learning, testing, and improvements.
Launching tonight.

Little throwback to when we first got the Haas into the shop. We spent about a week going through it, leveling it, cleaning it out, and making sure everything was in good shape before we actually started cutting parts on it. After we got it baselined, it was time to add the 20 tool tool changer – and put it to work!

At Perry Parts, we don’t just build the product. We also build the machines – that build the product. This new CNC machine helps us set a new standard and how we make our parts.
We used to be running an old Langmuir MR1 which did what we needed… But it was pretty slow, and took a long time to set up between different parts.
When Quinn at offered me his old CNC machine at king of the hammers for a price I couldn’t refuse – I said yes. And after the machine made its way from San Diego, to New Hampshire - it found a home in our shop. It took a little bit of time to get it in a spot that I wanted, in particular replacing the 10 tool ATC with a 20 tool unit, from a Haas VF1. But I’m pleased to say this thing is running, and cutting good parts for us!
What will we make next?

At Perry Parts, we do not 3D print from filament. The benefit of that is being able to print from materials that are typically not possible to 3D print. This is a great application of that. By 3D printing directly from industrial grade ultra high-performance urethane, we can literally hold up a roller coaster. And now, we do.
I wanted to share this one and got permission from the customer. We just recently passed their cycle fatigue testing, and longevity testing - blog post on the Perry Parts site coming soon!
