The TOPEM20 3D printer uses Slurry Extrusion Lamination (SEL) technology, which extrudes battery slurry from the printing nozzle instead of the traditional coating method. This makes the battery manufacturing process faster, simpler, and less expensive. It is a great design for batteries with unique structures or the manufacture of micro-batteries, solid-state electrolyte battery, fuel cells, and electrolyzer. This machine can be compatible with the glove box, please contact MTI for more information.

Compressed Gas Requirement pic1 pic2
0.5-0.8 MPa pressure required
The compressed air pump is required for the operation, which is not included in the standard order, please click the link below to order one.
Attention: If a gas cylinder is used instead of an air compressor(pic2), a two-stage pressure regulator(pic1) must be installed on the gas cylinder to limit the pressure within the required working range for safe operation. Click here to learn about the installation of a gas regulator.
