Proto Pasta Aromatic Coffee 1.75mm PLA 3D Printer Filament .5kg Spool
Proto-pasta's Aromatic Coffee PLA is the first specialty blend based on their new High Temp PLA formulation. This seemingly odorless plastic releases an invigorating roast coffee scent when heated. Beyond this novel feature, it is the most beautiful pearlescent, translucent bronze color when printed and becomes very wood-like when heat treated. Coffee PLA prints like standard PLA but has a potential Heat Deflection Temperature (HDT) of as much as 140C (285F) depending on post-processing. This means parts retain more stiffness and form at higher temperatures (no warping on your sunny car dashboard).
For maximum performance, your prints should be heat treated (i.e. crystallized) in an oven until you see a change from translucent to opaque. Yes, there is an obvious visual change indicating the improved performance! They had good luck in a lab oven at 110C (230F) for an hour or less. They 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 60C for any reaction) for a longer time with less risk of unwanted deformation.
No abrasive fillers so expect normal wear with standard nozzles.
Compatible with most PLA capable printers!
Some shrinkage may occur in the annealing process, so dimension critical parts may need to be scaled as much as 2.5% to compensate according to Proto-Plant.
