DIY High Resolution 3D Printer
Even though 3D printers have become mainstream and costs have declined, most cannot create a fine level of detail when printing. For rapid prototyping, you can fabricate one yourself such as the High Resolution DLP 3D Printer. Homemade yet still turns out impressive results.
The 3D printer uses a Digital Light Processing chip with a high resolution video projector to render each layer of the image on a resin which is cured by a UV laser layer by layer. Each 0.1 mm thick needs about 8 seconds to cure. As the photos show, the high resolution DLP projector renders pretty accurate results. Though, with 3D printing you can expect it to take several hours for each print job.
