Wematter Gravity 2020 SLS 3D printer


Wematter Gravity 2020 SLS 3D printer

Wematter, a Swedish manufacturer of SLS 3D printers, has launched a SLS 3D printer and an ecosystem supporting design engineers producing durable 3D-printed components in an office environment or workshop.

Launching the newest iteration, Gravity 2020, design engineers can print durable SLS 3D-prints directly at their office. Gravity 2020 has a build volume of 30x30x30 centimeters and an integrated powder handling system for ease of use. The printer itself measures 75x63x168 cm and the only installation requirements are one 230v 10A power socket, customizable by the customer, and one ethernet connection.

“We have worked hard to only use a standard 230v 10A socket and to comply with CE-regulations for IT-equipment so minimize the installation effort from our customers” – Robert Kniola, founder and CEO at Wematter.

The uniqueness is in the powder handling and mechanical properties. The Gravity uses pneumatic systems to transport, dose and also evacuate powder in a closed system. Special algorithms stacking 3D-models and calculating laser paths together with material scientists Wematter has shown exceptional mechanical properties in their printed parts. 

“Mechanical properties and ease of use has always been our main targets and we think it is the best path for changing behaviour towards additive manufacturing.” – Robert Kniola, founder and CEO at Wematter.

Founded in 2014, Wematter has been developing its SLS platform with the target to lower the barriers for the SLS technology. The founders Robert Kniola and Henrik Lundgren worked with SLS printers, injection moulding and milling and saw what needed to be done to get more engineers to work with SLS 3D-printing.

Cloud accelerated job preparation

Every Gravity SLS printer is connected to the cloud where every sensor, camera and electronics are exposed for monitoring and process control. The print jobs gets prepared in Wematter Deep Space and the machine code is sent to the printer from a computer, cell-phone or tablet. 

The user uploads .step or .stl files directly into the web application and prepares the 3D printer jobs from any computer.

You can plan your job with 3D prints and Wematters proprietary algorithms packs and stacks your job and places it in the queue and meanwhile, Gravity 3D printer warms up to start your command.

“We have put productivity and user-friendliness in focus so that more people can discover the benefits of Additive manufacturing.”  – Petter Johansson, VP of Engineering at Wematter.

Material science in focus

Gravity 2020 is prepared for a lot of different materials and in the beginning is shipped with Wematter Aurora, a PA11 based material. Wematter has co-developed it’s on nano-cellulosa based powder for three years with the goal of using bio-based reinforcement in additive manufacturing. A new research project has begun to introduce graphene based conductive materials for SLS 3D-printing. 

“The team is expanding rapidly and we will introduce new materials to the market the coming years to come. Our target focus right now is repeatability, durability and high precision in the process and the components.” – Henrik Lundgren, Co-founder and process manager.

Production ramp-up and shipping

Right now Wematter are shipping out Gravity 2020 to customers that has been collaborating in its development and are now starting to take pre-orders for Gravity and its ecosystem.

We are expanding our production capacity with the move to bigger facilities and also with the collaboration of new machine-building suppliers.

Right now we have the final assembly in our new facilities and with the high demand that we are getting from our customers we are ramping up production at an external facility in parallel.” – Robert Kniola, founder and CEO at Wematter.
