Why 3D printing can revolutionise mechanical puzzles for the world?
1) 3D printing is an additive manufacturing process which means it only adds material to the places you need it! This form of production allows for little to no waste in terms of material usage.
2) This unique method of production allows for limitless design possibilities. The range and complexity of design has no limits when it comes to 3d printing. Unlike something such as CNC machining, 3d printing allows complex internal parts which lead to unique puzzles that have never been made before!
3) Originally 3d printing technology was purely designed for prototyping. However the technology has progressed more than was initially perceived as possible. Thus 3d printing now being one of the rare manufacturing processes used in both prototyping and mainstream production.
