Combing Through 3D CAD Programs

Look around. Nearly everything that you interact with was likely a creation of three-dimensional computer-aided design (3D CAD) — homes, furniture, automobiles, lighting, smartphones, computers. At its most basic level, a CAD program takes a designer’s two-dimensional sketch and extrudes, or solidifies, that drawing into a three-dimensional model. Depending the industrial focus of the CAD program, and the modular extensions used to support and enhance its software, product developers and engineers are able to design extremely intricate products that can be built or manufactured. At Proto Labs, every single part submitted for manufacturing arrives as a 3D CAD model in one of several different file formats derived from different CAD programs. Continue reading

Started From the Bottom Now We’re Here: The Rise of 3D Printing

3D Printed Globe

It’s nearly impossible to have a conversation about the current state of manufacturing without mention of 3D printing, an additive process that uses digital CAD models to build physical, real-life objects, layer by layer. While additive manufacturing has existed for more than 30 years, it wasn’t until the last few that 3D printing, led by increased accessibility, has become the poster child for progressive technology within the industry — NASA prints telescope! Designers print runway pumps! Scientists bio-print human organs!

It’s undoubtedly an exciting time in manufacturing that has many eager to see what the future brings, but can the promise of a printed world withstand the heat? We deconstruct the layers of 3D printing to find the substance beneath the style. Continue reading

‘Proposed Revision’ Enhancement in ProtoQuote Makes Ordering Parts Even Easier

We hear it often: “How do I make my part moldable?” With the introduction of Proto Labs Proposed Revisions in our automated ProtoQuote® system, your part may qualify to receive our enhanced moldability analysis that automatically makes adjustments to areas like draft or wall thickness. Here’s how it works: Continue reading
