AND MY DESIGNS JUST KEEP GETTING BETTER. With our Dimension ® 3D Printer, I know my model will represent my idea exactly. And that makes it easier to improve my design with each iteration. Our Dimension is right here in the office, and that helps us get our products to market faster. The Dimension models we create are made in ABS, so they’re tough and durable. Leases start at only $275 a month, or you can buy a printer for under $15,000, so they’re also really affordable. Overall, Dimension gives me an amazing sense of freedom—and creativity.
