Aleph Obects makes available the LulzBot HS-Series Tool Heads. The new HS (hardened steel) tool heads enable 3D printing of industrial-grade composites, such as carbon fiber or glass fiber-filled polyamide (nylon) for high-strength 3D prints.
The LulzBot HS-Series Tool Heads are capable of printing industrial composites with a tensile strength yield comparable to PEEK (tensile strength of 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). The ability to create high-strength functional jigs, fixtures, and prototypes on-site in a matter of hours.
Featuring hardened steel components for maximum durability, these tool heads are purpose-built for high-strength 3D printing applications with abrasive and industrial composites. The hardened steel extruder hobb is optimally designed to minimize wear from abrasive composite filaments, and the larger heating block enables high-volume throughput of larger-diameter nozzles. Objects printed with the HS-Series tool heads will be stronger due to better layer adhesion and thicker walls.
The LulzBot HS Tool Head features a 0.8 mm nozzle for more precise high-strength 3D printing, and the LulzBot HS+ Tool Head comes with a 1.2 mm nozzle for high-speed, high-strength 3D printing. From the 0.25 mm SL (small layer) tool head to the new HS-Series tool heads, the LulzBot ecosystem offers a broader range of layer heights and filament capabilities. These new tool heads further expand the vast supported material palette and capabilities of LulzBot 3D Printers.
