How often do you come across an opportunity to increase – perhaps even double – the speed of your 3D printer? If that sounds too good to be true, the following may change your mind. The F770 large-format FDM printer is now capable of printing faster – from 1.5 to 2 times the standard print speed, depending on part geometry. It’s all thanks to a new high speed 3D printing head, designed to increase the material extrusion rate and ultimately get parts in-hand faster.
Since its introduction, the F770 printer has proven to be a dependable solution for delivering large-scale 3D printed prototypes and tooling. It fills a unique role by providing manufacturers with a large industrial FDM system at an accessible price point. With the longest heated FDM build chamber on the market, it’s intended for applications that require a generous print envelope but not the high-performance materials or capabilities of premium machines. It prints with ABS and seven colors of ASA thermoplastic, with three available layer thicknesses.
Despite these capabilities, the reality of printing large parts with extrusion-based additive technology is that time-to-print can be lengthy. That may require production schedules to be adjusted around the rate at which parts can be printed.
That changes with the new T25 High Speed print head, an easy plug-in replacement for the F770’s standard T14 head. The T25 head design incorporates several upgrades including increased drive motor torque and four drive gears to accelerate material feed. A redesigned hot end further improves performance, contributing to faster material deposition. Although it features a larger tip orifice (0.635 vs. 0.356 mm), the T25 head prints at the same 0.330 mm layer thickness as the T14 head, delivering comparable surface quality for most geometries. And it’s compatible with all seven colors of ASA material.
Speed tests with the new head have demonstrated very positive results and customer operations have also verified the improvement. In-house Stratasys testing showed speed multipliers in the range of 1.96 to 2.27 times typical speeds with the standard T14 head. One automotive customer saw a 2X difference when printing a large door-molding installation tool. In fact, the customer noted that this improvement has been transformative, enabling a shift to just-in-time tooling and allowing them to respond more quickly to the departments they support.
Whether you’re an existing F770 customer or researching your options, the new speed increase enabled by the T25 print head represents a significant step forward in F770 throughput optimization and large-scale printing productivity. It reflects our continued focus on refining FDM technology to benefit our customers through repeatable results, consistent performance, and efficient solutions.
