This tiny cannon was injection molded on my MakerBot 3D Printer...
Yes... You read that right.
And you can do it too... With no changes to your machine... In about an hour start to finish. No need to make a mold either. I'll supply that too to get you started. Here's a video showing how it's done:
This might be a game changer for owners of home 3D printers. Injection molding quality is the ultimate goal for layered deposition technology, but even today, with the most expensive printers, resolution is still no better than .001"... Easily seen by the human eye.
This is a continuation of my recent discovery oF how to use your 3D printer as an injection molder. http://www.thingiverse.com/thing:82666
The first part I made was a small ball. It didn't really show the capabilities of the process I dubbed "Injection Printing".
After publishing my thing, I went to the barn, got a handfull of old silicone dies, went through them and picked a couple I thought would make good tests of the process's limits. I also made a new, .175" diameter mold. I think the results might just be the discovery of the week:
I've published my findngs on "Instructables", the OTHER great innovation site. I've also entered this idea into the "Epilog Challenge V" contest there, so please visit it, read all about it, learn the details... And then try it...
Oh ya... And while you're there, please sign up and vote for this idea too :)
Oh... And in THE THING YOU NEED TO ADD BEFORE YOU CAN BE PUBLISHED DEPARTMENT; if you have a bench drill press where the depth limiter has gone knackered, you can download the replacement here.
Enjoy and Thank you very much.
