Marshall, Tuesday, 22 September 2026.
A Texas federal jury ordered Bambu Lab to pay Stratasys $27.6 million after finding willful infringement of four 3D printing patents, though no sales ban was issued.

Judicial Decision and Damages

On September 18, 2026, a federal jury in the U.S. District Court for the Eastern District of Texas, Marshall Division, awarded Stratasys approximately $27.6 million in past damages [1][2]. The jury found that four Bambu Lab-affiliated entities willfully infringed four of Stratasys’ 3D printing patents [1][3]. U.S. District Judge Rodney Gilstrap presided over the week-long trial which concluded recently [1][3]. This decision marks the conclusion of the first of two planned trials between the industrial additive manufacturing pioneer and the consumer-market competitor [1][5].

Patent Portfolio and Technical Details

The infringed patents cover specific technologies including force detection during fabrication and purge towers in additive manufacturing [1][4]. Specifically, patents US 9,168,698 and US 10,556,381 cover force detection, while US 9,421,713 covers purge towers [1][3]. Another patent, US 7,555,357, covers extrusion-based layered deposition systems [1]. This verdict resolves a portion of the intellectual property dispute, as Stratasys’ two 2024 suits allege infringement of ten patents combined [1][4]. The current trial resolved 40 percent of the total patents asserted across both cases [1][4].

Despite the finding of willful infringement, no injunction has been issued and Bambu Lab’s printers remain on sale as of September 22, 2026 [1][4]. Bambu Lab has publicly disputed the findings and signaled plans to appeal the legal battle over core 3D printing intellectual property [1][5]. A second lawsuit involving remaining patents related to connectivity and material-tracking remains pending with no trial date set [3][4]. The jury’s award covers past damages only, leaving future market dynamics for mid-tier additive technology uncertain [1][5].
