Hi Everyone,

I noticed that the new mini has a lot of structural parts that are injection molded. Does anyone know what there composition is? Especially for the Y-axis motor mount. I want to print with polycarbonate in an heated enclosure, so I want to know a bit more about the possible heat deformation issue that I might run into. My Prusa MK3S has been upgraded to polycarbonate structural parts for this reason. I appreciate any insight you might all have. 

Thanks,

They are made of the same PETG as the printed parts. There is an article somewhere on the blog (that I dont have the energy to look fo right now 😅) explaining how some of the printed parts rarely change and take up a very large part of the time needed to manufacture the mini. They have also chosen npt to recycle failed prints/leftover filament into new filament due to quality concerns.

So the reason given for the injection molded parts is to save time and to waste less material.

 

The community has been worried about this beong a step away from the core principle of being able to make your own parts. But they promise it's not. With the design files still being open and printable I believe them.
