Glass fiber reinforced filaments (Glass Fiber, GF) are one of the most interesting technical families for anyone producing functional components. Adding short glass fibers to the polymer matrix, typically nylon (PA-GF), polypropylene (PP-GF), PETG-GF or ASA-GF, increases stiffness, dimensional stability and temperature resistance, reducing shrinkage and warping compared with the base material.
Compared with carbon fiber, glass fiber retains a certain toughness and a lower cost, making it excellent for brackets, supports, jigs and fixtures, components under load and parts for hot or industrial environments. Printing requires high temperatures (roughly 250-300 C depending on the matrix) and in many cases an enclosed chamber. Glass fibers are highly abrasive: a hardened or stainless steel nozzle is essential. For filled nylons, drying the spool before and during printing is crucial.
In the product pages we state the matrix, the reinforcement percentage and the recommended temperatures. Ideal for workshops, prototyping and industrial maintenance. The Strato3D team can help you choose between glass fiber and carbon fiber based on loads, temperatures and budget.
