About BIGTREETECH
BIGTREETECH (often abbreviated as BTT) is a Chinese brand specializing in electronics, control systems, and upgrade components for desktop 3D printers. The brand is best known for developing high-performance 32-bit controller boards, silent stepper driver solutions, touchscreen interfaces, and advanced expansion modules for hobbyists, makers, and professional users. BIGTREETECH products are widely used in both custom-built printers and upgrades for popular machines from manufacturers such as Creality, Anycubic, Artillery, Sovol, and Voron. [1]
The brand operates under Shenzhen BIQU Innovation Technology Co., Ltd., alongside its sister brand BIQU, which focuses more on complete 3D printers, hotends, extruders, and general printing accessories. BIGTREETECH primarily serves the electronics and control hardware segment. [1]
History
BIGTREETECH was established in 2015 in Shenzhen, Guangdong, China, one of the world’s largest electronics manufacturing centers.
According to the company, its founder—identified as Eric—started the business after discovering that affordable, feature-rich controller boards for DIY 3D printers were scarce. Using an initial investment reportedly funded by a university scholarship, he began designing replacement control boards aimed at hobbyists seeking more performance and flexibility than existing 8-bit solutions. [1]
The company’s earliest products focused on replacement printer mainboards compatible with open-source firmware such as Marlin.
Rise to Popularity
BIGTREETECH gained significant recognition between 2017 and 2019 for several innovations.
Trinamic Silent Drivers
One of the company’s first major successes was introducing affordable boards compatible with Trinamic (TMC) silent stepper motor drivers.
Features included:
- Near-silent motor operation
- Sensorless homing
- Higher microstepping
- Improved motion quality
These capabilities became increasingly common in consumer 3D printers after their introduction. [1]
SKR Series
BIGTREETECH became widely known with the release of the SKR motherboard family.
The SKR series offered:
- 32-bit ARM processors
- Faster computation
- Larger firmware capacity
- Easier firmware updates
- Modern expansion interfaces
At a time when many hobby printers still relied on 8-bit AVR boards, the SKR family became one of the first affordable high-performance replacements. [1]
Company Philosophy
BIGTREETECH describes its mission as:
“For Makers, By Makers.”
The company emphasizes:
- Open-source compatibility
