For one Dutch, 28-year-old man named Jasper Menger, both these technologies play an integral part in a new 3D printer which he unveiled at RapidPro 2015 in Veldhoven earlier this month. Menger who runs a company called 3D Robot Printing has create a 3D printer which is tethered to a traditional robotic arm, similar to one seen within a typical manufacturing facility.
Working on the project for over two years now, Menger only recently got the technology to the point where it could reliably print out very large objects using a process that’s similar to fused
The machine which Menger presented at RapidPro 2015 utilized a Staubli TX200, 6-axis, heavy payload robotic arm. With a reach of 2.19 meters and a compact base which enables self mounting, the arm is able to expand on the typical build envelope of a traditional FFF 3D printer. This means that the machine is able to go almost anywhere that an attachment is possible, and print incredibly large objects. On his website, Menger states that he can create machines which have a build envelope of anywhere between 1 x 1 x 1m and 8 x 3 x 2m depending on the exact robotic arm he uses.
“I was surprised that no one had come up with this idea earlier on,” Menger explained to 3dprintmagazine.eu. “The beauty is that the robot is smarter than the 3D printer. A robot has only a few points in order to make the proper movement. Besides, you have six axes available.”
The machine does not use standard 3D printer filament, instead relying on granulate material which is run through a hopper and then extruded at a
As for the uses for such a machine, Menger is already using it to print out molds for the hulls of fiberglass boats, and he’s not simply satisfied with the statis quo. In fact he already is in the early planning stages to use his robotic arm approach to print using metals such as steel, reduce costs, and make the machine even larger.
It will be interesting to watch this entrepreneur as he continues to innovate within this field. Let us know if you saw this printer in action earlier this month, and what your thoughts were.
