Quorten Blog 1

First blog for all Quorten's blog-like writings

Here are some interesting and useful 3D printing tips on PotatoFi’s blog. Flat steel sheets versus textured ones? Textured ones work well with printing PETG plastic, flat ones for PLA.

Here is an example of a nice printout using PETG plastic. Also, PrusaPrints.org is now competing to be a replacement for Thingiverse? Yeah, a lot of politics, and unfortunate if we see the earlier one get taken down, but at least that’s a good thing to be aware of.

The textured plate surface results in very professional looking 3D printed plastics, with that nice ground surface texturing that you see in many commercial electronics plastic surfaces.

So, what is PETG plastic? Is it similar to PET plastic? Yes it is. Awesome! You can print with polyester terephthalate! The “G” is for “glycol modified,” this chemistry modification mainly aims to lower the melting point to make 3D printing easier.
