3D printers are undoubtedly cool. And they can also be useful — assuming what you need to print can fit inside the typically tiny dimensions of your printer. On that count, you should have no troubles with the BigRep Large Scale 3D Printer. This mammoth machine can print objects well over a cubic meter in size, or roughly 45" x 40" x 47" at its limits, and doesn't skimp on detail, either, with dual tool heads offering 100 micron resolution. Print a table, print a chair, print your imaginary best friend — just print something, because owning one of these and failing to use it would be a real shame.
