3-D printing 100 times faster with light
by University of Michigan
Rather than building up plastic filaments layer by layer, a new approach to 3-D printing lifts complex shapes from a vat of liquid at up to 100 times faster than conventional 3-D printing processes, University of Michigan researchers have shown.
3-D printing could change the game for relatively small manufacturing jobs, producing fewer than 10,000 identical items, because it would mean that the objects could be made without the need for a mold costing upwards of $10,000. But the most familiar form of 3-D printing, which is sort of like building 3-D objects with a series of 1D lines, hasn't been able to fill that gap on typical production timescales of a week or two.
