Can you anneal HT-PLA?
Yes you can anneal HT-PLA but the effects are minimal compared to HT-PLA-GF.
What is in HT-PLA?
HT-PLA is a PLA-based multiphase composites, it's main structure is PLA materials.
What is High Temperature Stability?
The ability to withstand temperatures without deformation while not under a load.
Can it print with PLA settings?
Yes! This material prints great with generic PLA settings.
Is it hygroscopic?
It has similar hygroscopic properties to PLA.
Is it UV / Weather resistance?
Similar to generic PLA, no material-modification for UV/weather resistance, we need further testing.
What is the shrinkage rate?
Very minimal, similar to generic PLA.
Is it dishwasher safe? (Food safety, water steam)
This depends on the 3D print and how sturdy it is. If you have thin walls they may be subject to warping due to the harsher environment.
Is it abrasive?
Polymaker™ HT-PLA is non abrasive so no hardened nozzle required.
Can you print with a smaller nozzle?
Yes, you can print with 0.2mm nozzle or smaller.
What is the highest speed you can print at?
HT-PLA can print up to 300mm/s.
Does all the color has the same heat resistance?
Yes, all of the colors and variations have the same heat properties
Is it biodegradable?
The resin matrix of HT-PLA contains only a small amount of non-biodegradable components. Therefore, we consider it to be a material with good biodegradability similar to polylactic acid.
Is it strong?
The layer adhesion is fairly low, not recommended for single wall prints.
Does it has fumes when printing?
It will be similar to standard PLA
Can I anneal HT-PLA in boiling water?
Yes you can, however if you have hard water with high mineral content, boiling your part can cause the minerals to form a white dust coasting on the surface.
