Design Rules Revolution: DMLS Requires New Thought Process

By Heather Thompson, Senior Editor, Medical Design and Outsourcing

As product development speeds up, the design rules are changing. Nowhere is this more apparent when looking at the industrial 3D printing process of direct metal laser sintering (DMLS). Direct metal laser sintering is an additive manufacturing technology with significant potential in the medical device space. But it requires a new way of thinking even at the early design phases. In many ways it represents the transition designers must face when looking at new technologies to make medical device design and manufacturing faster and more innovative. 

Internal channels that are impossible to machine are achievable with DMLS.

There are several benefits of DMLS explains Tommy Lynch, metals project manager at Proto Labs Inc., primarily that designers can prototype designs in unusual shapes at both time and cost savings. “DMLS is different from other 3D printing because you are using real metal. Many of these materials have been used for industrial applications for decades.”

Lynch says designers like the process because they can experiment with organic shapes that can’t be readily machined. For example, one intriguing opportunity is the ability to build implantable body parts that are custom fit to the recipient. “These implants would normally need to be delicately built on a 5-axis machine at a high expense,” he says. “Technology exists to scan a person’s actual bone structure, and print a direct DMLS replacement.”

DESIGN TIP: Improving Part Design with Uniform Wall Thickness

Designing parts with consistent wall thickness is a fundamental rule of plastic injection molding, and ignoring it can lead to sink, warp and inaccurate or non-functional parts. Yet the functional requirements of consumer, medical, aerospace and industrial products often leave designers little consideration for the material flow and fill properties of plastic, both of which are at least partially determined by wall thickness.

Pay close attention to rib-to-wall thickness ratios. To prevent sink, the thickness of the rib should be about half of the thickness of the wall.

This month’s tip discusses:

  • Guidelines to avoid cosmetic defects associated with thin and thick features
  • Material alternatives to improve wall thickness consistency
  • Important questions to ask about material properties
  • The benefits of design for manufacturability analysis

Innovative Catalytic Reactor Incorporates Metal 3D Printing

Minnesota-based start-up Activated Research Company recently launched its flagship product, the Polyarc™ catalytic reactor — built in part with Proto Labs’ 3D printing process of direct metal laser sintering (DMLS).

A DMLS stainless steel block that attaches to a gas chromatograph, the reactor accelerates the process of analyzing the composition of matter and is useful in industries ranging from fuel to pharmaceuticals, according to Andrew Jones, a chemical engineer, who, along with former Proto Labs CEO Brad Cleveland, founded Activated Research in 2014.

The Polyarc™ microreactor was 3D printed in stainless steel with direct metal laser sintering technology.

Fans of TV’s “CSI” are likely familiar with a gas chromatograph. The evidence from the crime being investigated goes into the crime lab’s gas chromatograph, the high-tech machine quickly identifies whatever is in it and a dramatic arrest ensues.

That’s great for a TV crime series, but the show glosses over how, in reality, as Jones explains, the chemical or composition analysis is quite expensive and time-consuming.

That’s where the Polyarc™ reactor comes in. It can quickly quantify carbon-containing chemicals in a sample without the slow, costly calibrations of existing methods.

The idea for what would become the Polyarc™ reactor originated with researchers at the Catalysis Center for Energy Innovation led by Paul Dauenhauer, a professor of chemical engineering at the University of Minnesota. Dauenhauer’s group published a paper proposing a “quantitative carbon detector” based on their research, which received funding from the U.S. Department of Energy’s Office of Basic Energy Sciences.

On-Demand Webinar: Choosing the Right Rapid Manufacturing Method

We recently hosted a 30-minute webinar on: Choosing the Right Rapid Manufacturing Method for Plastic Parts. If you missed it, no worries. You can still watch it on-demand HERE.

What did you miss?
We discussed the benefits of rapid manufacturing for plastic components and how to select the correct manufacturing process:

  • 3D printing, machining and molding processes and specifications
  • Material selection and properties for each process
  • Advanced molding materials like thermally conductive plastic and liquid silicone rubber

Top 3 Questions Asked
How long will you keep a mold and do you inform the customer if you’re going to get rid of it?
We’ll store the mold for one year from the last order unless it is requested to keep in storage, and we’ll notify the customer of inactivity to if they would like the mold disposed of or retained in storage.

Is there any limit on volume for injection-molded parts?
No, you can get injection-molded parts in quantities of 25 to 10,000+ with several molds even surpassing 100,000 parts. We have the ability for single and multi-cavity molds dependent on size and complexity.

Can Proto Labs be used for light pipe assemblies in PC, PMMA and silicone?
Yes, we have molded countless parts in those materials for light pipe assemblies. Mold finish should be polished to a SPI-A2 with special attention made to the mold build for ejector pin location, gate location and parting lines.
