3D printing a small part please?

[TRE Cup]

I have a small nylon sleeve that Porsche does not sell separately. It is approximately 15 x 8 mm x 2 mm wall thickness

I would probably buy 10-20 of them if the cost is right
Appreciate suggestions on someone that can do these , hopefully in the L.A. area

thank you

What is the sleeve for? What direction are the loads on it? I'd probably draw it up in CAD and test print it on an FDM printer. Once it fits appropriately have it printed with some more industrial printing process like SLS or MJF.

Rotational load using the small cast in tabs on the outside of the sleeve. It actuates a micro switch that clips into place over the sleeve, on the door handle

so the load is quite light
The sleeve slips onto the door lock cylinder (1986-89 handles) and gets inserted into the door handle. When you turn the key left or right, the notch on the sleeve is inset to the lock cylinder and rotates 90 degrees either left or right triggering the microswitch

Ok, yeah I have a feeling with FDM printing it will probably wear pretty quickly and not have a very smooth action because of all the layer lines. I think your best bet is to have the final parts printed in a powder based process like SLS or MJF because the parts are homogenous and have a consistent surface finish. Plus you can usually order parts to be post processed to have a smoother, more injection molded-like finish.

Above my "pay grade" on the tech aspects that you describe above. THANK you for the advice and will use this in my search when we talk to suppliers

I used Sculpteo to so some small parts in PA12 using multijet fusion. Great detail and the cost was reasonable. Not local but turnaround was fairly quick.

If you have a CAD model, you can upload it to Xometry or ProtoLab and get a quote in different materials/technologies. Based on my experience, machined plastic parts still have superior mechanical qualities to even the highest end of 3D printed parts and the cost isn’t that different for simple geometry.

[SBell]

I haven't used scuplteo but I've used shapeways , which is similar, with good results for small amounts of parts. If you have enough to meet their minimum, 3Dhubs offers decent quantity discounts but I think they have a $100 minimum so you'd probably need to order more than 10-12 pieces. All three have pretty good online price calculators.

So the next question is who can scan this part for me? That way we can check with the different type of manufacturing processes

cool stuff guys!

[SBell]

It seems the choke point here is having a CAD model of it. If you can't find anyone to make a CAD model for you, I can do it but I'm in the bay area at the moment. I don't have a scanner so I'd have to have one of the parts to take measurements off of.

Dave,

I’ve got a 3D printer, so that’s not a problem.

My sister has a brand new scanner still in the box I can get a hold of.

Thingiverse is a website that does have some Porsche parts already digitized and ready to print.

Can you post a photo of the sleeve? Maybe we can locate a STL file somewhere on the web.

Here is a photo of the door lock knob available on that website. You never know, maybe your sleeve has already been digitized.

[RNajarian]

Not your sleeve but a pretty obscure part.

Just wondering Dave..? have somebody done the 3D printing for you?

I'll TXT you tomorrow with the contact info for a friend that runs a prototyping company in Santa Ana. (Among other things he has built fully operational prototype cars for a lot of manufacturers.) This is a lot smaller then what they generally do but he would definitely know where you could get them fabbed for the lowest cost
