Micronics: Desktop SLS 3D printer for home use

The manufacturer Micronics wants to make selective laser sintering (SLS) printing affordable for home users. SLS uses a laser to fuse plastic powder into solid objects layer by layer. A technique that has mainly been used in industrial printers to date.

In contrast to conventional 3D printers, SLS does not require support structures for overhangs or undercuts. The powder bed fully supports the components during printing. This means that even highly complex, interlocking geometries can be produced without restrictions.

With its new printer, Micronics aims to offer full encapsulation with closed material transfer and simple powder recovery. A special screen box for separating printed parts and unused powder and a removable vacuum cleaner for surface treatment ensure an orderly, clean workflow.

The core component is the galvo scanner system. Computer-controlled mirrors guide the 5-watt laser precisely over the powder bed. According to Micronics, numerous details such as laser control, heating and slicer software have been redesigned for home use.

According to the manufacturer, the component accuracy is around ±0.2 percent and a minimum of ±0.1 millimetres. Layer thicknesses of 100-150 micrometres can be achieved at a maximum speed of 67 mm/h. The build volume is 160 x 160 x 200 mm.

Nylon 12 will be the standard material for the market launch; other materials such as TPU, reinforced nylon and polypropylene are planned. The compact dimensions of 310 x 330 x 700 mm and a weight of 19 kg should make the printer suitable for home use.
