WHITE PAPER: Choosing the Right Material for 3D Printing

We have a saying here at Proto Labs, “Materials Matter.”

To learn more about selecting the right material for 3D printing, download our free white paper.

Indeed, material properties are an especially key piece to consider in the case of industrial 3D printing, or additive manufacturing, which is different from traditional manufacturing methods.

To help you sort through the properties — from tensile strength to yield strength, elongation at break to hardness — we’ve published a comprehensive new white paper, “Selecting the Right Material for 3D Printing.” The paper explores recent improvements and advancements in materials used in 3D printing, and then goes in depth to cover materials that work best for three frequently used technologies: direct metal laser sintering, selective laser sintering and stereolithography.

This new white paper is part of a range of resources in our online library of 3D printing content that includes design tips, case studies, videos and other white papers. We also have a staff of experienced customer service engineers who can discuss design questions that may arise. Find us at protolabs.com or call us at 877-479-3680.

The New Automotive Disrupters: Tech Giants

The automotive industry has stood as the life blood of American manufacturing for decades. It is the heart of the Detroit economy and in recent years has faced many challenges, but some of the greatest challenges have just begun. Tech giants such as Google, Apple and Tesla, to name a few, are poised to drive new levels of competition. It’s fair to say these companies qualify as a Big Bang disruption that is a major industry change instigated by non-traditional players in the market.

Most of us still think of the automobile primarily as a tool to bring us from point A to point B, but cars and trucks have become so more than just transportation. Many modern cars are a fully connected infotainment system that just happen to be on four wheels. The automobile has become a mobile conglomerate of computer and technology devices — a true command center supporting the driver with much more than just driving.

Another way to look at this shift is with the electronic device industry. A decade ago, the handheld GPS was a very common and useful tool. Today, GPS navigation is almost an afterthought on your smartphone since it’s as simple as downloading a user-friendly app. This is just one of many seismic digital shifts in the past 10 years.

However, while the technology-based companies leading the electronic infiltration into the automotive world certainly have the computing chops, the knowledge, depth and infrastructure that comes with manufacturing electronic components for the automotive industry is still developing. These tech giants must acclimate to model years and multi-year platforms compared to frequent software updates — two fundamentally different ideologies colliding.

Awards Season at Proto Labs

Proto Labs and its employees have been lucky enough to receive recent awards from one national organization and two Minnesota-based publications.

Manufacturing Leadership Award
We took home Frost & Sullivan’s Manufacturing Leadership Award in the Customer Value category. The nomination was based on the customer value created through Proto Labs’ interactive quoting system with DFM analysis. Other winners in the same category include Cisco Systems, Diebold, Lexmark and Dow Chemical.

Community Impact Award
Minnesota Business Magazine presented us with a 2016 Community Impact Award in the Youth Initiative category for the efforts of the Proto Labs Foundation and its contributions to STEM programming. Since 2014, the Foundation has provided nearly $350,000 in large grants to nonprofit organizations, like Code Savvy, for their programs and initiatives that support STEM education.

Titans of Technology
Proto Labs’ EVP and CTO Don Krantz was selected by Minneapolis/St. Paul Business Journal as an honoree at its 2016 Titans of Technology awards, which celebrates outstanding technology professionals. Krantz was recognized in the CIO/CTO category, which honors a top IT executive of a public, private or nonprofit company.

TIPS WITH TONY: Replace Metal with Plastic to Save Weight, Cost

To decrease weight and potentially cost, you can replace metal with plastic on certain parts through 3D printing and injection molding. At Proto Labs, we use industrial 3D printing process stereolithography (SL) to produce thermoplastic-like parts that have a nickel coating on the surface. This offers the increased strength of aluminum die-cast components, without the weight. With injection molding, the introduction of thermally conductive plastics has broken new ground when looking for heat dissipation of expensive heat sinks.

Stereolithography parts built with SLArmor have a metal coating applied over a thermoplastic-like base.

SLArmor involves a ceramic-filled DSM Somos material, which has a metal coating applied to achieve the look, feel and, most importantly, comparable strength of aluminum without added weight. SL is a cost-effective prototyping method for initial parts that mimic metal before moving to higher volumes of die-casted parts.

The material properties of SLArmor are greatly improved in regards to heat deflection, tensile strength, elongation at break and elasticity. The chart below shows exactly how the material relates to die-cast aluminum in three different thicknesses that can be applied based on geometry of SL parts. Note that the thickness of the nickel plating may vary on each part due to the ability to apply the coatings.

WHITE PAPER: Aluminum Tooling for Optical Moldable Silicone

Dow Corning recently published a comprehensive white paper on the use of aluminum tooling for moldable optical silicone. It examines two big questions:

  1. To achieve a high-quality finish on the molded parts, what type of optical-grade surface finish is required for the tooling used to mold the silicone optics?
  2. Can this be achieved with an aluminum injection mold or is tool steel required to provide parts with an optical finish?

Proto Labs’ aluminum tooling is a reliable indicator of future optical silicone moldability.

Read why integrating optical silicone into your development cycle with rapid injection molding is an effective strategy, and why aluminum tooling is a reliable indicator of future moldability.

Why use optical moldable silicone? It’s a relatively new material to the market, but it is quickly gaining popularity as a replacement for glass components in many optical and lighting applications. Its benefits include:

  • clarity
  • heat resistance
  • durability for use in outdoor and automotive applications
  • design flexibility for fine features
  • an ability to combine multiple parts into a single unit
