Technologies for More Effective Medical Component Manufacturing Seen at MD&M West 2018

Advancements in 3D printing, automation and inspection technologies were prominent at this year's Medical Design and Manufacturing West show.

This year’s Medical Design & Manufacturing Expo West (MD&M West) show in Anaheim, California, featured various new technologies that can enable manufacturers of medical components to become more efficient and effective. From 3D-printing hardware to automation solutions to tabletop CNC milling machines, this trade show had a lot to see.

Walking the floors of the expo, it was clear that additive manufacturing has thoroughly infiltrated the world of medical manufacturing. Nearly every small-parts producer promoted its additive manufacturing capabilities, and many manufacturers of 3D-printing solutions exhibited there. Customizable implants and rapid prototyping capabilities seem to be highly valued in this corner of manufacturing. According to Ultimaker North America President John Kawola, the benefits of rapid prototyping are only just being explored, and there is a lot of potential to unlock.

It seems the world of medical manufacturing runs on two concepts: precision and cleanliness. Medical devices and implants must meet exacting specifications without any environmental contamination, and I feel much more at ease walking into the doctor’s office after seeing how exacting the medical standards can be. For example, Darren Bjork, vice president of medical-parts manufacturer Metro Mold & Design Medical (MMD Medical), told me the company has made great strides in cleanroom machining. I also stopped by the Quality Vision International booth and spoke to Marketing Manager Alyssia TenBrock, who showed off the company’s multisensor array: an inspection device that combines a laser, touch probe and visual scanner. The system speeds the workpiece-scanning process by eliminating the need to recalibrate or change-out sensors, a notable time saver in an industry that demands precise tolerances with literally life-and-death consequences. 

Onshape drew a significant crowd at MD&M West as it released the public beta version of its browser-based CAM software VisualCAM, developed by MecSoft. A cloud-based CAM system, the software enables users to share CAM iterations using highly secure, password-locked internet links, avoiding the need to download or upload files, not to mention eliminating the expensive hardware needed to store files. The system also saves iterations of a design, so file management is said to be of no concern.

In the same hall as MD&M, the Automation Technology Expo (ATX West) showcased automation solutions for manufacturing. Omron had a large display area showcasing its offerings. Its most prominent display, however, was Forpheus, the ping-pong-playing robot. While it may seem trivial, the technology that went into Forpheus is intensive, including visual scanners; swift, precise movements; and machine-learning capabilities. The extensive scanning suite is capable of reading human facial expressions and body language to judge skill, using that information to teach the human player to play better ping-pong. The company uses this technology in the rest of its robotics and scanning technology, providing adaptable and precise automation solutions.

Universal Robots (UR) has a different approach to automation. Instead of focusing on achieving the highest speed and precision possible, the UR collaborative robots (cobots) use sensor technology that enables them to function safely alongside humans in a shared area, unlike conventional industrial robots that operate autonomously inside a safeguarded cell. Sensors detect when the cobot unexpectedly contacts an object, be it a person or something else. They then immediately stop their motion to prevent injury or damage. Moreover, the UR cobot is designed to be easy to program—a feat that was done by booth visitors in just a few minutes, making it easy to adjust to various jobs in a low-volume machining environment. The cobots on display included a “zero-footprint” model that can attach to girders to perform functions without interfering with other shop activities. According to UR Sales Manager Craig Tomita, the cobot can also attach to a rail system to perform part loading/unloading for multiple machine tools.

MD&M West, along with ATX West, provided numerous examples of the dynamic landscape of manufacturing today. Whatever problem a shop may be facing, be sure that technology providers are in heated competition to find the solution.


  • Adjusting Supply Chains in U.S. Manufacturing

    As the novel coronavirus presents challenges for manufacturers and new opportunities for suppliers, manufacturers should not miss the chance to strengthen their supply chains.

  • Recognizing the Swiss Advantage

    A growing number of job shops have realized that multifunction Swiss-type lathes can make them more competitive. This Ohio shop explains how and why it integrated its first Swiss-types and shares some of what it has learned along the way.

  • Starting with the End in Mind: An Exit Strategy for Machine Shops

    John Shegda and Eric Wilhelm each had different ideas about how they wanted to phase into retirement. The exit strategies for the three successful manufacturing businesses the two men operated included a mix of seeking equity groups, selling the business, or transitioning into an employee stock ownership plan. All it took was a friendly suggestion from a mutual friend to set them on a different path.
