Well that didn’t work as expected

Last Saturday, we met up and testing our platform. We let it heat up to 480 F and made sure the system could maintain temperature. We added plastic and nothing happened. Smoke started coming out of the bottom of the nozzle and it made perfect rings. As seen in the video.

We got to a point where we thought nothing was going to change and we pulled out the piston to find this.

This is a combination of burnt plastic and melted plastic at the piston. My guess is the temp was too high and once the lower stuff burned it was over. This is why we have the Plan B. We already had the parts and the design was finalized.


The Doors Open

Back in May, there was a challenge by Inventables.com to see who could be the first group to create a extruder that could make plastic filament for 3D printing. Doing some research into the raw plastic and I found that it is quite difficult to find any plastic that’s not in huge quantities.  There are a few on eBay but they lack any nice colors or options. We are opening our doors with 15 different types of plastics and colors.

  • ABS – Black, Green, and Gray
  • HDPE – Black, Almond, Dark Red, Green, Blue, Orange, and Mahogany
  • PP- Pink, White, Green
  • Poly carbonate- Gray
  • PLA- Natural

We know that a big source to home made filament will be recycled materials. Buy some of our plastic and use it to add colors and volume to your home made filament.  As time goes on we will add more types of plastic and more colors. We are located in Leominster, MA and it is a great location to purchase plastic. After all, it is the plastic capital of the world!  We look forward to doing business with you.
