Drawing of Carpet Cleaner
Below are links to three images of a prototype making machine. It makes plastic parts from 3-Dimensional computer models. Once I have created a 3-D model in a program I use called Pro Engineer, I save the file into a format type called "stl." This file is sent to the SLA (prototype) machine. Inside the machine is a vat of liquid plastic resin that turns hard when exposed to intense ultraviolet light. A perforated stainless steel plate acts as a support for the part being made. This plate is the platform portion of an elevator system. The platform begins at .004" below the top surface of the resin. The machine has interpreted the 3-D model as a series of cross-sections taken every .004". A UV laser strikes a mirror that moves position to draw the first cross section on the resin creating a solid layer .004" thick. The elevator moves down another .004" and the resin is spread over the hardened layer. Then the laser draws the next section. The process repeats until the entire part has been drawn layer by layer. Then the elevator rises up out of the resin. The part is baked in a UV oven for an hour then lightly sanded. The result is a highly accurate plastic prototype part. The images show a finished prototype bottle rising up out of the vat. At my company, we have made very small gears and have make operational pumps with prototype parts. In the past, cruder prototypes were made by hand to test designs. They took months to make and cost several thousand dollars. The machine will work around the clock and create the parts in anywhere between 1.5 and 40 hours. Our SLA machine can make any part that will fit inside a 10.25 inch per side cube. There are machines with vats that can accommodate 24 inch per side cubes.
