What to 3d print?

I am self employed and use / own a seat of solidworks. I am very busy right now with work (why am I replying to a thread on the Samba, again?) but would be more than happy to help out the cause here when time permits.

For my work I use solidworks for metal stamping tool and die design. We do not get into any complex lofted surfaces or anything.

The storage compartment door lock seal looks somewhat like and serves the same function as the engine compartment door lock seal, or the door handle seals. So, it is outside, in the weather, and exposed to sun and all.

WCM makes the door handle seals and engine cmpt door seal (and license plate light seals and other stuff like that) and I have used them for years with little trouble. In time, they do get brittle, but then, so do the original VW ones. Especially here in New Mexico where the UV is rough on seals and interiors.

Here are two photos of an intact seal in the gallery. In both photos, it is the one on the right:

Ah....yes. Same issues as door handle seals. Over the years I have seen them made of the original rubber....then plastics like polypropylene and polyethylene blends which stay flat for ages but seal poorly because they lack elasticity....to relatively modern TPE/TPV (thermoplastic elastomer/Thermoplastic vulcanizate ) blends like Santoprene ...which is polypropylene resin packed with EPDM particles.
EPDM is what is used for windshield rubber and brake cylinder cups. There are over 120 variations of Santoprene....so you have to carefully select what you need for your application.

Santoprene or a variant of it is most probably what the better parts are made of.

Its much less difficult to process than typical rubber. It works like a fairly low pressure PP plastic with lower temps and less demolding issue. It an also be re-melted.

For a thin low relief part like that gasket its possible it could also be vacuum formed from sheet in something like santoprene. Ray

i posted this in the other 3d printer thread but, i own a full aluminum/bronze foundry, a solidworks 2015 license ,a 3d printer and a patternmaker(i dont technically own the patternmaker but he is always here Smile

). so if there is anything at all that needs to be cast in ,plastic, resin etc or metal. we can handle it, i have always wanted to make stuff for the cars but i really didnt know what woudl be the best piece to start with any suggestions? i like this thread.

it woudl be super easy to make inside sliding door handles in aluminum, i could also nickel plate them to boot! maybe ill start with that...

i have my patternmaker building me a pattern and core box set so i can sand cast them in aluminum and then i can plate them. i will post pictures in another thread and keep you guys posted, im stoked! no more broken handle! i am going to just cast the square adapter into the actual casting....

As far as the rubber seals go I know it is possible for a 3d printer to print rubber but I have no idea how well it would hold up. What I'm really hoping our school gets is a scanner so we can stick a piece in and it will scan it then replicate it out of whatever material the 3d printer will print. That would come in really handy. I am also taking a class next year which will get me more experience in solid works and programs like that.

yes there are a number of different filament materials like rubber,and also wood! its crazy some of the stuff the filament guys are coming out with, but the fact remains that the tech is still limited in its practical applications. i look forward to the day i can print a metal piece that isnt a million dollars to buy the machine, and the printable area is larger than a bus! on a side note the sls tech has produced the hardest alloys we have seen yet which is a side affect of sintering in general,that is cool!

Wonder if you could find material that would work for printing out the red warning light at the bottom of the cluster, between the speedo and the clock.

Thanks Tcash for a good find.
I've asked them if they can supply it in clear plastic as my 1973 Westy has it that way.

I've been printing Westfalia sink faucet bases (for the faucet with the city water lever and rotary electric switch on the '76 - '79 campers) and tonight I've been printing 11-tooth gears for the speedo's odometer drive shaft. So far so good!
