Stratasys wins $27.6 million lawsuit against Bambu Lab: landmark verdict on patents
A Texas jury has ordered Bambu Lab to pay Stratasys $27.6 million for infringing four 3D printing patents. The Chinese manufacturer has already announced an appeal against the ruling.
The decision represents a turning point in the legal battle that began in August 2024, when Stratasys sued the emerging manufacturer, accusing it of using patented technologies without authorization.
The four patents at the center of the case
The jury examined four U.S. patents owned by Stratasys, rejecting all invalidity arguments presented by the defense.
The patents involved in the first phase of the trial are identified by the numbers: 9,168,698; 10,556,381; 9,421,713 and 7,555,357. The jury found that Bambu Lab infringed all four patents.
The protected technologies concern fundamental aspects of 3D printing. Bambu Lab had attempted to challenge the validity of the patents, but the jury rejected this defense.
- Damages: $27.6 million in favor of Stratasys
- Infringed patents: all four of those contested (9,168,698; 10,556,381; 9,421,713; 7,555,357)
- Bambu Lab announces appeal
- Legal battle began in August 2024 with two separate lawsuits in Texas
Who are the protagonists of the dispute
Bambu Lab is a fast-growing manufacturer that markets 3D printers through Shenzhen Tuozhu Technology Co. and Bambulab Limited.
The Bambu Lab brand has gained popularity in recent years in the desktop 3D printer market. The company operates through two main entities that develop and sell products under the unified brand.
Stratasys, on the other hand, is a veteran of the industry, with decades of experience and a broad patent portfolio. The U.S. company has built its market position also through intellectual property protection.
A broader battle
The Texas case is only the first chapter of a much broader legal dispute between the two manufacturers.
In August 2024, Stratasys filed two separate lawsuits in Texas against Bambu Lab and related companies. The case just concluded involved only four of the contested patents.
The battle is also being fought before the U.S. Patent and Trademark Office. In June, Bambu Lab won a partial challenge against a Stratasys patent, while Stratasys successfully defended another one.
One of the patents that Stratasys successfully defended before the USPTO is the same one involved in the Texas lawsuit. This strengthens the American company's legal position.
Implications for the industry
The verdict could redefine the competitive balance in the desktop and industrial 3D printing market.
A damages award of $27.6 million represents a significant sum for any manufacturer. For Bambu Lab, which has grown rapidly in recent years, the financial impact could influence future strategies.
The case also raises broader questions about patent protection in the additive manufacturing sector. Emerging manufacturers must now assess intellectual property-related risks more carefully.
Next developments
Bambu Lab has announced that it will appeal the ruling, prolonging the legal battle.
The appeal process could take months or years before a final conclusion. Meanwhile, the other lawsuits filed by Stratasys against the Chinese manufacturer remain open.
The final outcome will determine not only the amount of damages, but could also impose restrictions on the sale of certain Bambu Lab printer models in the United States.
The 3D printing community is closely watching this dispute, which could set important precedents for future patent disputes in the additive manufacturing sector.

Q&A
What is the compensation amount ordered for Bambu Lab?
A Texas jury has ordered Bambu Lab to pay $27.6 million to Stratasys. This amount concerns the established infringement of four specific 3D printing patents.
How many and which patents were infringed according to the ruling?
The jury found that all four patents challenged by Stratasys were infringed, identified by numbers 9,168,698, 10,556,381, 9,421,713, and 7,555,357. The invalidity arguments presented by the defense were completely rejected.
What is Bambu Lab's next legal move after the verdict?
The Chinese manufacturer has already officially announced the filing of an appeal against the verdict issued by the Texas court. Therefore, the legal battle does not end with this initial verdict.
When and where did this legal dispute formally begin?
The legal battle began in August 2024, when Stratasys filed two separate lawsuits in Texas against Bambu Lab and its related companies. The recent trial concerned only the first phase relating to four patents.
Are there other venues besides the court where the lawsuit is being fought?
Yes, the dispute is also taking place before the U.S. Patent and Trademark Office (USPTO), where both companies achieved partial reciprocal victories in June. However, the Texas verdict strengthens Stratasys' position on the patents involved.
