Extrusion is a continuous process where plastic flakes are inserted into the hopper and extruded into a line of plastic. These lines can be used to make new raw materials such as 3d printing filament, make granulated plastic, spinned around a mold, or used by you in new and creative ways.


Plastic flakes are heated and injected into a mold. It’s a relatively quick process which is well suited for creating small objects repeatedly. You can make the molds completely yourself by using CNC mills or lathes, or by simply welding them.

Build the injection molding machine


Plastic is heated inside the oven and slowly pressed into a mold with a carjack. Well suited for making large and more solid objects, the oven itself is also a great machine for prototyping and making plastic tests with.

Build the compressor


Plastic waste is shredded into flakes which will be used in the other machines to create new things. You can select the output size of these flakes by changing the sieve inside the machine to create different patterns and processes.
