LulzBot HS Tool Head Hardened Steel 0.8mm


 The LulzBot HS Tool Head is purpose-built for high-strength 3D printing applications utilizing durable industrial composites and is ideal for engineers needing strong parts and faster printing times.

Featuring a hardened steel nozzle and extruder hobb, this 3D printer extruder head is capable of printing high-strength composite polymers on par with PEEK's tensile strength (15,200 psi - ASTM638). These polymers are used in a wide range of high-demand applications, from structural components to the automotive industry.

Parts printed with these composites have higher impact resistance, resist deformation, while retaining strength in harsh and demanding environments. Industrial materials like PA-CF Low Warp combine strength and dimensional stability (less than 2% elongation at break - ASTM638) with the ability to perform in higher operating temperatures up to approximately 120° C (248° F).


A large heater block, a massive melting zone, and a 0.8 mm nozzle balances speed, detail, and strength.
