French maker Lynxter has introduced OVERTIME, a patented add-on for its S300X LIQ21 and LIQ11 silicone printers that extends unattended run time by up to 36 times. The company says the full build volume can then be filled in a single job, which suits series production of silicone parts. It will be shown at Formnext 2026 in Frankfurt, with no price or availability date given.
What does OVERTIME change in practice?
With the longer run time, a job can use the whole build volume in one autonomous run, so more parts fit on a single plate. Production no longer has to be split into several jobs, which makes planning simpler. Larger parts, thin-walled complex geometries at higher resolution and long prints also become feasible, according to Lynxter.
Which printers and materials are supported?
OVERTIME is a compact module designed to fit most S300X LIQ21 and LIQ11 machines already installed worldwide. It works with the silicones SIL-001, SIL-002 and SIL-004 and the COPSIL-0550, COPSIL-1050, COPSIL-2550 and COPSIL-4050 ranges, with nozzles from 0.40 to 1.00 mm. Some older S300X versions need an adapted print head, which Lynxter offers.
Where does it sit in the silicone market?
Lynxter names silicone seals, protective and masking tooling and medical devices as target uses and frames the launch as a step from technology pioneer to production supplier. It follows the company's NEST modules and the food-contact SIL-004 silicone. Other routes to longer runs include light-cured single-component resins from Stratasys with Shin-Etsu and Axtra3D, and heat-cured deposition systems from innovatiQ and Prayasta. The preview takes place at Formnext, 17 to 20 November, Hall 12.1, booth B71.
What it means
For manufacturers considering silicone AM, run time has been a hidden constraint on batch size and planning. If the claimed gain holds, full-plate unattended builds could lower labour per part and make short series of seals or masking tools more predictable. Price, availability and independent proof of unchanged material performance are still missing, so a business case should wait for those figures. Existing S300X owners may find the retrofit route attractive, but should confirm compatibility of their machine version.
Frequently asked questions
What is OVERTIME?
A patented add-on from Lynxter that extends the printing autonomy of S300X LIQ21 and LIQ11 silicone printers by up to 36 times.
Does it fit existing printers?
It is made for most installed S300X LIQ21 and LIQ11 machines. Some earlier S300X versions need a modified print head, which Lynxter offers.
When can it be bought and at what price?
Lynxter has not disclosed pricing or a general availability date. A preview is planned at Formnext 2026, booth B71 in Hall 12.1.
