3D printing in metal resulted in fewer bacteria and greater food safety
3D printing in metal was chosen as a solution and Marel quickly began to redesign the support element specifically for 3D printing, so that it took full advantage of the technology’s possibilities. The support element is in direct contact with food, so bacteria can accumulate in all cleaves, joints and openings, and these bacteria can be transferred directly to the meat. That’s why we were really excited about the possibility of 3D printing the support element in one piece, and the weight reduction was also a positive element, as the support element moves MANY times a second, says Matias Taul Hansen, Technical Designer at Marel
3D printing is a much cheaper solution than cutting out the item, and compared to laser cutting, 3D printing is also preferable, as we avoid joints where bacteria can accumulate. By 3D printing in titanium, we also achieve a lower-weight item that is cheaper to produce and that can work faster, says Kristian Rand Henriksen, consultant at the Danish Technological Institute.
