Heat-Resistant 3D Printing Filament Compound (Modified PLA)

About This Product

This grade is a polylactic acid compound carrying a heat-resistant modification, supplied as a pellet compound for extrusion into 3D printing filament. PLA is an aliphatic polyester built from lactide, the cyclic dimer of lactic acid obtained by fermenting plant sugars, and it is a rigid thermoplastic that prints at low temperature without a heated chamber. Unmodified PLA crystallises slowly, so a printed part is largely amorphous: above the glass transition the chains gain mobility and the part softens under its own residual stress. That is why standard PLA prints deform at modest temperatures, why a PLA part left in a car or near a heat source loses its shape, and what rules PLA out of most functional applications. The heat-resistant modification raises the temperature at which the part yields under load, so printed parts hold their geometry at higher service temperatures, extending PLA from prototyping into functional use. Because heat deflection also depends on wall thickness, infill and layer bonding, confirm the service temperature on printed specimens. Supplied as a raw material for processing on the buyer's own line; we do not produce finished articles. It is used in engineering filament, functional 3D printed parts and filament manufacture. Bio Green Chem supplies the heat-modified PLA filament compound to specification on polymer base, pellet form, moisture content and heat deflection behaviour.
