With its EBM S400, Stratasys Inc. has ushered in a new way of making titanium parts. Producing fully dense parts in Ti6AL4V and Ti6AL4V ELI, the Electron Beam Melting technology eliminates the common barriers to working with titanium. Stratasys is the North American distributor for this unique rapid prototyping device that is manufactured by Arcam AB.
"The high speed electron beam system is the next generation of additive fabrication technology for rapid manufacturing of titanium parts," says CEO Scott Crump. "The machine creates parts comparable to wrought titanium and better than cast titanium, with a 95 percent powder recovery yield, which is unheard of in our industry." The company states that the EBM technology is three to five times faster than comparable laser-based machines. Titanium parts created on the system are accurate, near-net shapes and are HIP treatable. The company also offers cobalt-chrome and has ongoing material development for alloys that include stainless steel. For more information, go to http:// rbi.ims.ca/4933-544.
The Beam Store from Suitable Technologies is managed by remote workers from places as diverse as New York and Sydney, Australia. Employees attend to store visitors through Beam Smart Presence Systems (SPSs) from the company. The systems combine mobility and video conferencing and allow people to communicate directly from a remote location via a screen as well as move around as if they are actually in the room.
An MIT research team has invented what they see as a solution to the need for biodegradable 3D-printable materials made from something besides petroleum-based sources: a water-based robotic additive extrusion method that makes objects from biodegradable hydrogel composites.
