Dutch Startup Tesseract Wants Linear Motors on Every 3D Printer

Most 3D printers still move their printheads with belts and pulleys. The setup is cheap, but belts stretch, vibrate and lose stiffness over time. Those flaws show up as surface ripples, softened edges and dimensional errors. Dutch startup Tesseract Technologies thinks it has a better answer: a linear motor built from scratch that the company says is two to five times more cost-effective than competing industrial systems.

How it works

Where a belt drive links a motor to a carriage through a stretchy band, a linear motor pushes the carriage directly. Magnets sit along the axis and coils sit in the carriage. Nothing elastic sits in between. The result is higher speed without losing detail, better repeatability and performance that does not degrade as parts wear. Closed-loop control continuously measures and corrects the carriage position, so a bumped printhead returns to the right spot instead of ruining the layer.

Cost and design

Tesseract says it reached that price point by designing every element in-house: motor hardware, control electronics, sensor technology and firmware. The team uses a database of more than 15 million viable motor models and applies an optimization process that relies on widely available materials and electronics. The system is already running on machines such as the FELIX Pro XXL from FELIXprinters.

What it enables

Multiple carriages can move independently on the same axis. That means several toolheads or gantries can work on one part at the same time, rather than simply moving a single printhead faster. It also removes belts, pulleys and transmission components from the design, opening up layouts that a conventional setup would make impractical. The commercial launch is planned for the first quarter of 2027.
