This Instructable will guide you through the steps to create objects with 3D filament scraps.

These "scraps" are actually made with real wood sawdust (30% or so) and renewable resources such as corn starch or sugar cane. I am using PLA filament or Polylactic Acid.I recommend only using PLA as other 3D filaments may need venting of the fumes they create. I decided to do this project outdoors, anyways.

We will melt these cast-offs into silicone molds and create jewelry, key chains and other like objects.

I saved the support material from my prints for 3 years to complete this very project, so, start saving now.

Supplies

Wood Filament Support Scraps
Blender
Toaster Oven
Silicone Mold Of Your Choice

Step 1: Blend the Contents

The first order of business is to ground up your filament scraps as fine as possible.

I did this with a blender I purchased at a second hand store. It was missing a few feet, so I printed new ones.

I use every button on the blender, because I can and it seems to work well grinding the filament down.

Once you feel that the scraps are fine enough, it's time for step two.

Step 2: Fill the Mold

Step 2 is about filling your silicone mold. I solely use silicone because of its ability to absorb high temperatures. You don't want your mold to melt. There are so many varieties of molds out there, pick a fun one and be sure they can handle temps to 400 degrees or better..

I fill the mold to the top as the filament will melt down as it heats. You can add additional filament powder after it has melted somewhat. So prepare for that.

Step 3: Melt the Wood

You will need a toaster oven for this step. I suggest that you go back to the thrift shop and buy a dedicated toaster. I wouldn't use the one in your kitchen, just in case. I was lucky enough to find mine in a dumpster (don't ask). I cleaned it up and printed new shoes for it, as well. Check the video, it's awesome if idontsaysomyself.

Anyways, preheat your oven between 300 & 350 degrees - temps may vary.

I bake for about 15 minutes and then check the progress. If it has melted down a bit, I may add more filament powder. That is up to you.

Once the top surface is flat and smooth, you are done.

Step 4:

Remove your hot mold from the toaster oven using oven mitts or something similar. Place onto a trivet or something that can handle the heat. Let it sit for at least 5 minutes or until cool to the touch. Admire your creation and contemplate your future uses. I, for one, am going to screw in an eye-hook and string it around my neck. There are a ton of uses, so be your creative self. If you have other ideas, please feel free to write them in the comments below.
