What is Glass Fiber PLA and when should I choose it over carbon fibre?
It is a PLA composite with glass fibre carried in the matrix. Glass fibre is the usual choice when the job is rigidity and dimensional stability rather than maximum stiffness - fixtures, jigs, alignment blocks and parts that must hold their measurements in workshop conditions. Carbon-filled grades suit jobs where stiffness and creep resistance lead. Both are abrasive composites and both print in the 195-225 °C PLA window with a hardened or steel nozzle.
