PETG is becoming more and more popular for home 3D printing.
But what are the best tweaks to choose when you are 3D printing with PETG?
Its almost impossible to get exactly the right slicer configs the first time.
What is PETG Plastic?
PETG, or polyethylene terephthalate glycol, is a common thermoplastic with unique properties.
Its always worthlearning about 3D printing filament typesto ensure you use the right ones for each of your prints.
PETG has a higher melting point than PLA.
Always read the recommendations from the filament manufacturer when you first start with a new material.
Movement/Print Speed
PETG is more sensitive to print speed than other 3D printer filament materials.
Moving too fast will cause under-extrusion and poor layer adhesion while moving too slowly causes over-extrusion and blobs.
You may have to experiment with your print speeds to get the best results.
A retraction speed between40mm/s and 80mm/sis a good place to start.
Most slicers provide control over the overhang angle and support throw in.
An overhang angle of 0 degrees will support all overhangs, while 90 degrees will support nothing.
This makes50 to 55 degreesa good place to start.
This means that additions are usually not needed when working with PETG.
Wipe towers and other nozzle-clearing additions can be worthwhile to prevent stringing and blobs.
This ensures that the layers adhere well and prevents what little warping would occur with strong cooling.
Most modern build surfaces work well with PETG, thanks to its strong layer adhesion.
3D Print With PETG
PETG is a great 3D printer filament option.
Its always worth taking the time to learn about 3D printer filaments before you use them at home.
