BIGTREETECH TD1s by AJAX and BIQU

BIGTREETECH TD1s by AJAX and BIQU – Instant Filament Transmission Distance & Color Analyzer

The BIGTREETECH TD1s is a compact, professional-grade instrument engineered for 3D printing enthusiasts, designers, and filament manufacturers who demand precise, repeatable material data. Jointly developed by AJAX and BIQU, the TD1s dramatically streamlines your workflow by instantly profiling filament optical properties—combining transmission distance (TD) measurement and accurate HEX color capture in a handheld, USB-C powered device.

Key Technical Features

Precision TD Measurement: Accurately quantify the Transmission Distance (TD) of 1.75mm filament with ±7.5% accuracy, unlocking true-to-life color and opacity calibration for advanced 3D “filament painting” applications.

Instant HEX Color Coding: Built-in high-resolution optical sensors and digital calibration algorithms generate exact HEX color codes, enabling seamless digital asset creation, render matching, and color-critical work.

Dual Operating Modes

Quick Capture Mode—captures a material’s TD and HEX code in a single shot, perfect for quickly growing your HueForge material library.

Continuous Capture Mode—monitors live TD data as filament is used or spooled, making it ideal for both print-room and production environments.

HueForge Software Integration: Natively syncs with HueForge, effortlessly adding and updating filament parameters for realistic simulation and slicing in color relief, lithophane, and artistic workflows.

Standalone OLED Display: Bright, built-in OLED screen displays measurement data in real time, allowing field use without a computer; ideal for routine QC and quick manual entry.

Universal Connectivity: Simple plug-and-play USB-C interface ensures compatibility with Windows, Mac, and Linux systems, as well as modern power banks or wall adapters.

Form Factor & Build: The TD1s comes as a ready-to-use, injection-molded device—smaller and quicker than previous iterations, robust enough for field and factory floor.

Application & Workflow Enhancements

Eliminate the need for painstaking lightbox setups or printed test swatches.

Directly insert a filament strand to obtain TD & HEX color data in seconds—significantly reducing filament waste and setup time.

Reliable accuracy means you can trust your digital renders and color prints to closely match the real-world filament’s characteristics.
