Developing medical device parts is a high-stakes process, and material choice is an important decision. The specific requirements for the part or device being developed will help steer the decision on which material option is the best choice.
When designing parts for injection molding, you may need to consider finishing options, which can help improve a part’s mechanical properties, enhance surface finishes, facilitate the final assembly process, or just further customize your part or parts. A common finishing option is part marking, through using either pad printing or laser engraving.
Engineers, designers, and product developers have found that industrial-grade 3D printing and plastic injection molding work well together in the life cycle of a product, starting with the design-risk mitigation of 3D printing prototyping and then shifting to the manufacturing method of injection molding to ramp up for higher volumes.
When building a part with 3-D printing, the machine’s resolution can have a significant impact on the final part by determining the minimum feature size, surface finish quality, and cost. Stereolithography (SLA) 3-D printing is available in three resolutions (normal, high, and micro) for a range of part geometries. Most parts can be built in normal resolution, but high resolution may also be required.
Protolabs helps remove the speed bumps created by tedious quoting times with an automated system that provides an interactive quote within hours of uploading a 3D CAD model.
You can make adjustments to the surface finish, material, and delivery of your parts inside the quote, and pricing will update in real time. The quote also highlights any potential design issues — from draft to material flow — and recommends immediate solutions. The result is quality parts shipped to you really fast.
