Need a plastic part? Just print it.

Hi Guys
Ever needed a specialised bracket, lever or part...
Just model it in Alebra (or your favourite modeling package) and·send it off to a service Bureau for printing. (Yes, 3D colour printing). I've just had some holders and brackets·made up in nylon and they're amazing. One day they're images on your PC, the next day they arrive in the post. I use a South African company but here is the web site of one of the many US service providers.

Not too expensive for small parts and usefull for the robot fanatics among you people.
This is a small gear arm I did. It's·about 100mm long (4 Inches)
Kind regards from Kwa Dukuza - South Africa

Since there is no online quote, could you give an example of price you paid for parts and is it a good idea to do multipul up to fit machine size for better price for more than one part.

Perfection in design is not achieved when there is nothing left to add.
It is achieved when there is nothing left to take away.
I was wandering around a local craft store (Michael's) one day, and spotted some books on polymer clay, which is essentially a moldable plastic clay. It's basically PVC powder that is mixed with a plasticizer. It can be shaped, molded, etc. like real clay. It can also be baked like clay, which hardens it into a solid plastic structure.
Except for not wanting to bake PVC in the same oven that I would cook with, it looks like a cool method for building robot parts.
The printer cost alot, but budgets are weired and allowed the purchase of such an amazing device.· Students make models with Autodesk Inventor and import it to the zprinter software and click print.
They included a small bit of playdoh for casting things.
I had picked it up to fix some plastic pieces on my neices camera that had broken. Worked alright, but man does it stink!!
it can be sanded smooth too!

Don't visit my new website...
Most of the info that I've found on the web has been geared towards arts & crafts, jewelry, etc., so if anybody uses this stuff for robotics, you'll probably be a pioneer in the field!

Can't remember what I paid for it, but I had customs charges too!
