Porsche is Now 3D Printing Some Parts!

Porsche Classic has been hard at work trying to supply more parts to classic Porsche owners. It's too expensive to build tooling for limited production run vehicles like the 959, or small parts for a variety of classic Porsche's, so Porsche has turned to 3D printing the items instead. What do you guys think of Porsche 3D printing parts? Do you think we're going to see hobbyists starting to DIY 3D print parts themselves down the line?



Clockwise, from top left: Spare part for 356B and 356C, filler cap seal for 959, crank arm for 964, spare part for 911 Speedster.


Source here and here.

I have 3D printed parts from a member here for my heater ducts. Love them. Done right it can work well. Now you can 3D print carbon, aluminum, even Ti.....Koenigsegg 3D prints parts like turbo housings and impellers! So why not!

Amazing technology and a great way to reproduce small parts that are otherwise NLA.

Bugatti 3D printed the titanium brake caliper on the Chiron too. I'm excited to see what the future holds for 3D printers hobbyists. It'd be awesome if we can 3D print our own replacement parts!

Is there a lot of work required after the 3D printing? My friends 3D printing plastic right now have to do lots of sanding to get things perfect right now. I know they're still tinkering with settings, but currently is it possible to have 3D printed items come out perfect?

I'm already at it...



These are all still at the prototype stage with a couple more in the pipeline.
One of which I'm REALLY excited about

Shapeways is a great resource with good quality printing resolution (first two parts are untouched stainless from their process) and can print in many different metal, ceramic and plastics.

I read this and excited that Porsche is continuing their support of the older models.

Beautiful work too Munky King!

How does the metal 3d printing hold up? Too lazy to google.

Carnegie-Melon engineers figured out how to 3D SS and it's stronger than billet plus more ductile!

Have your cake and eat it too!

My understanding, is the method how 3D printers turn material to liquid form, dispense, then cool, would be just like cold working SS.

That's my understanding.

Thank you.
I've not risked any components with any specific strain or cycling to them yet - mostly just eye candy stuff.

That Hackrod car looks amazing!

Anyone else seen the bridge 3D building equipment? The robotic printer moves around the structure, taking away the limitations of the printer footplate size.

I've also heard of plumbers having their vans tooled up for plastic printers, so that they can print special parts, rather than trying to find them at a warehouse.

Slade is an old colleague, good buddy and great dude. He's brilliant!

Printing still seems a bit slow for plumbers to make parts on site, but i love the idea.

I started a drone business with my first airframe design completely printed. We still use printed parts for production aircraft, opposed to injection molding. Albeit, we target a niche market, but if I need to increase production numbers I can affordably get additional printers these days.

Curious what the costs are to develop the blueprints for the Porsche Classic produced parts. The headlight washer nozzles for the 76-77 early turbo and Carrera 3.0 would be a good candidate for this technology. $800-1000 used seems silly. Even the clips are a few hundred for what is probably a couple dollar part.

Once I get my parts working, I'm going to make them 'open source'.

Honestly, I don't have the time to sell them or clean them up, so if anyone wants them, they can print them in whatever material they want.

If you have something you are looking for, you can either scan it, or ask someone to draw it for you and then print it on Shapeways or similar.

There are limits and frankly, there are also some inherent risks - another reason why I wouldn't sell mine. If something fails with a newly designed printed product that harms someone or causes expensive damage, who is at fault? The printer? The CAD drafter? The person who pays to have it printed? Am I falling foul of any copyrights (though SEMA could be the savior here) or patents?

There's a whole world of litigation just waiting out there for a trial case. I'm guessing the Porsche parts have been through rigorous testing and are backed by the company insurance. Mine... not so much

Many things with today's printer technology just don't make sense part wise too. Either $220 for a dash pad cover from our hosts or ??How much?? To print one. So for the time being it's appeal for part replacement is going to be limited to small fiddley stuff where tolerances are reasonably open, or can be machined post printing for critical dimensions.

Thanks for the explain Munky. Lots of legal and personal liability I'd not considered. Regardless, there's still a bit of ear-to-ear grin left in it to produce parts for yourself. Nice work!

Not Porsche, but sister manufacturer (under VW) Bugatti. Not vintage part, but current production:
Designfax – Technology for OEM Design Engineers
Printed to near net shape, then machined to final configuration. It is possible that we may see something similar on a Porsche soon. A 3-D printed titanium brake caliper.
