Three world records in 3D-printing of rare materials

Wematter can proudly present three major accomplishments that are on the world record level. Since its founding, Wematter has focused on a user-friendly SLS 3D-printer that is so easy to use that it can be placed in offices, hospitals and laboratories.

This is a part of the team developing new materials at Wematter.

Another major focus has been on being a world leader in materials and being able to offer really good mechanical properties and unique materials. To date, Aurora PA11 is the material most commonly used in Wematter’s Gravity machines.

One rare material, in 3D-printing, that has a strong demand is PP (Polypropen) and there are very few suppliers who can offer that material. Now, Wematter is one of those companies that can print PP (Polypropen) in an SLS-3D printer; which is the first record.

Wematter is currently getting ready to go to market with our Aurora Polypropen powder. Please find preliminary data for this product in the sheet below.

Another thing that is rare is the preparation of polymers in powder form for use in powder bed machines, such as SLS or MJF. For four years, Wematter has researched and analyzed to find a process for making its own powder, based on the raw material PP (Polypropen) in pellet form.

From self-made plastic pellets with nanocellulose to polymer powder for SLS-printers.

Now, Wematter is a 3D-printer manufacturer that have managed to make its own powder and printed it in its own SLS 3D-printer. That is the second record.

Perhaps the biggest news is that the material contains Nanocellulose made from forest raw material. This means that you can print PP (Polypropen) as a composite with stronger properties than if you had printed the parts in PP (Polypropen) only. This is record numer three.

It is a unique event that Wematter as a Swedish 3D-printer manufacturer of highly advanced 3D-printers has, with the help of Swedish actors, produced a powder that can be used in our Gravity machines. It’s been four tough years but now we’re starting to see the light in the tunnel. – Robert Kniola, CEO, Wematter.

About the  project

The material has been developed in a consortium within the framework of the research project Ampoform . Ampoform stands for Additive manufacturing of prosthetic products based on forestry raw materials. The project is led by RISE, within the framework of BioInnovation, and on the journey are four companies in addition to Wematter that help make this a reality. Stora Enso contributes with nanocellulose, Fillauer Europe develops prostheses and Ortopedteknik/Örebro county works with orthopedic solutions for patients. Read more about Ampoform here.

Wematter has printed several different parts for prosthetics in different materials and the aim is to print demonstrators that can be used by patients in need of tailor-made sustainable prints.

About Wematter

Wematter is a Swedish manufacturer that makes advanced SLS 3D printing technology available to companies looking to accelerate their product development and additive manufacturing. Wematter also develops its own suite of cutting-edge 3D-printing software that makes it easier for designers, engineers and manufacturers to use SLS 3D printing for the next generation of products.

With Wematters DNA, the focus is on the user experience, simplicity, durability and performance. This makes Wematter attractive to top customers such as Siemens, Volvo and Husqvarna. The company was founded by mechanical engineers who worked with SLS, SLA, FDM 3D printers and also injection molding and CNC milling. Since its founding in 2014, Wematter has delivered 3D printers and 3D prints to car manufacturers, hospitals and aerospace factories.
