Bambu Lab faces $27.6 million damages after losing 3D printing patent case
A Texas jury ruled that Bambu Lab's X1, P1, and A1 series 3D printers infringe on Stratasys patents covering prime towers and bed leveling. The court awarded Stratasys $27.6 million in damages. No injunction was issued, and Bambu Lab is reportedly developing alternative technology.
Stratasys holds more than 2,600 patents in 3D printing, many dating to the 1980s, and its foundational FDM patent expired in 2009, which helped open the consumer market. The disputed patents cover single-nozzle filament purging and strain-gauge bed leveling. Bambu Lab's newer H2 and X2 models use dual-nozzle designs and optical sensors that reportedly avoid the contested claims. Prusa Research's INDX toolchanger also sidesteps prime towers by wiping pellets into an internal waste cup. Bambu Lab stated it will pursue post-trial review and appeal, and no injunction currently blocks sales of the affected machines.
This verdict could reshape the consumer 3D printing market by discouraging smaller manufacturers from relying on similar purging and leveling techniques, potentially raising costs or limiting design choices for hobbyists and educators. Bambu Lab's appeal may delay any immediate financial impact, but the case signals that legacy patent holders can still assert broad claims against newer entrants. Consumers may see price adjustments or feature changes in future printer generations as companies seek to avoid litigation.
