Tips&Tricks

It prints like PLA on non-heated beds with tape. This Matte Fiber is not overly brittle, but is stiff and will break under excessive load. The material can be heat treated to retain more stiffness to higher temperatures. Dimensional stability is improved compared to HTPLA without fibers. The plant-based fibers improve adhesion of glues and coatings.

This material does absorb moisture and dry filament is recommend for best results. When saturated with moisture, this material oozes more readily. Lowering flow and/or temperatures can minimize oozing and improve detail, though higher temperatures are recommended for best mechanical properties. With higher temperatures, ooze artifacts can be removed post build.

Application
Architecture, sculpture, industrial and product design, engineering 3D prints.

How to do “Heat Treatment”
Bake your parts into a oven until you see a change from translucent to opaque. There is an obvious visual change indicating the improved performance! Good results were achieved in a lab oven at 110 °C for an hour or less. We recommend leaving the supports on your parts, placing them on a non-radiating surface (like glass, ceramic, or composite), and letting them cool in the oven to minimize distortion. Parts can be baked at a lower temperature (though must be above 60 °C for any change to occur) for a longer time with less risk of unwanted deformation.

TIP!
When you anneal a material like PLA materials it means that the plastic will continue to harden when exposed to low but consistent heat. Annealing will cause any 3d printed objects to temper, making it significantly less brittle and extremely tough. If done correctly, annealed parts will be resistant to warping, and maintain its original shape and structure.
However it may slightly shrink, so any critically-sized prints may be scaled up slightly by about 2 to 2.5% to make sure it will still fit any adjoining parts.

Due to all the different types of hot-end it’s extremely difficult to give a temperature advice. Please consider these tips, provided by the manufacturer, as a starting point to find the temperatures that work well in your setup. You may have to adjust the temperature settings slightly based on your type of printer.
