Mcor Technologies is known for their funky yet, brilliant 3d printing technology. They print using office paper as their raw materials. It's environmentally friendly and extremely affordable (at least for the materials). Just late yesterday WHEB partners, announced that they have invested €6.6 million into Mcor. It should be interesting to see what the company decides to do with the funds. This could definitely help them become a larger player in the 3D printing space.
