The image below outlines the unique features that the other materials bring for more demanding applications. The choice you make is down to you. PETG doesn't like to be squished onto the bed so much as PLA, so lift the nozzle slightly; I use 0. It also helps to know when to use PETG, and when PLA is fine. PETG is known for sticking sometimes too hard to certain surfaces (It has been known to remove glass shards from glass beds). for use as a container or tool, but not an ingredient), but PETG (Polyethylene terephthalate glycol) is a different thing and is not on the list. Prusament PETG on the other side should be behave more like one would expect from PETG. ABS 60°C to 21°C 0. For a 200mm parts this is approxmatly 1. . Essential for 3D printing enthusiasts who desire optimal results. The reason PETG is annoying me is i’m building an adapter for a dehydrator, and given the temps it’s subject to I HAVE to use PETG on a very thin detailed part. That's due to the carbon fibers making it extremely ridged while PLA is a fairly weak material. CR-PETG, Cost-effective with multiple advantages . Their material properties are similar to those of PLA and PLA+. I’m debating between PETG and PLA+. PLA, PETG, and ABS are among the most widely used 3D printing materials, each offering distinct advantages in terms of chemical composition, mechanical performance, ease of printing, and applications.
