@ 3Dex: I am looking for temperatures from 90 till 120 °C. It´s just about fabricating my own filament (I´ve built my own

@ AZERATE: That´s great to hear, thanks for the advice.

I saw an article saying talc powder can act as a nucleating agent when mixed in small proportions with PLA https://www.researchgate.net/publicatio … Composites

Anneal it afterwards and your prints should in theory have higher HDT.

Edit: Also, look at this technical data sheet for 4032D:
http://www.natureworksllc.com/~/media/T … .pdf?la=en

"When formulated with nucleating agents, product may be crystallized to achieve
parts with higher HDT than its amorphous counterpart. This is a high molecular weight biopolymer grade that processes easily on conventional extrusion equipment. Common nucleating agents are talc, ethylene bis-steramide and propriety offerings from third party suppliers"



OR ignore all that and maybe just go with Natureworks 3D850, they say its specifically made for 3D printing and has a HDT of 144C.  http://www.natureworksllc.com/~/media/T … .pdf?la=en

Whether you are looking to simply extrude and experiment with printing or analyze the makeup of the material, I'm sure they would play ball for educational purposes. In the few times I've spoken to them, they were good people.

Not sure of any sellers of that combination but I might be able to help. What properties are you looking for in your filament? (e.g what temperatures do you need it to withstand?)

Cheers

do you know any manufacturers who fabricate/sell such a compound? Within the scope of my master thesis, I need to fabricate my own high temperature resistant PLA and compounding my own stuff would be too time-consuming.

Thanks in advance!
