LulzBot releases HS-Series Tool Heads for High-Strength 3D Printing

Lulzbot, the open-source brand of the FDM 3D printers from Colorado-based manufacturer Aleph Objects, has released the LulzBot HS-Series Tool Heads for filaments with exceptional mechanical and thermal properties.

The HS (hardened steel) tool heads are capable of extruding industrial-grade composites, such as polyamide (nylon) infused with carbon fiber and glass.

High-strength FFF 3D printing

Earlier this year, LulzBot released the LulzBot Mini 2 and the Aerostruder v2 Micro tool head for high-precision FFF 3D printing rivaling that of parts manufactured using the stereolithography (SLA) process. Now, the company is further advancing FFF technology with its HS-Series Tool Heads – which feature hardened steel components for maximum durability.

The tool heads’ extruder hobb minimizes wear from abrasive composite filaments and maintains a large heating block for a high-volume throughput of larger-diameter filaments. With 0.8 mm and 0.25mm nozzles, and a 1.25mm nozzle for the HS+ Tool Head, LulzBot is said to “offer a broader range of layer heights and filament capabilities than ever before.”

3D printed parts created using the HS-Series tool heads have been tested and demonstrate a stronger layer adhesion and thicker walls. As a result of its capabilities of processing industrial composite materials, the tool heads can process filaments with tensile strength yields comparable to PEEK. Such materials are used for high-demand applications, particularly in structural automotive components.

Furthermore, industrial materials such as colorFabb’s PA-CF Low Warp filament, which has the mechanical properties of PA6, as well as enhanced printability and moisture control, can be used with the tool heads for high-strength functional jigs, fixtures, and prototypes. Additional properties using similar materials include a higher impact resistance and resist deformation.
