A higher profile for industrial-grade 3D printing over the past decade has led to notable technology developments and potential new applications. The buzz over 3D printing, or additive manufacturing, has also created a lot of speculation in the trade press about whether this technology, which has been around for more than 30 years, is poised to make a giant leap forward in capabilities.
“We are just now starting to see the fruits of these developments,” said Rob Connelly, vice president of additive manufacturing for Proto Labs, referring to a spate of recent announcements about advancements in new machines, materials, and software.
We recently interviewed three leaders from the 3D printing industry for insight into the current and future state of 3D printing:
- Rob Connelly, Vice President, Additive Manufacturing, Proto Labs
- Patrick Dunne, Vice President, Advanced Application Development, 3D Systems, which manufactures and sells 3D printers
- John Murray, President and CEO, U.S., Concept Laser, a global provider of 3D metal printing systems
Product designers in need of prototypes or end-use parts frequently turn to CNC machining for its quick-turn capabilities. Machining isn’t new, but just like any other digital technology, its functionality has expanded in recent years.
That’s why we assembled some tips for how to get the most out of today’s CNC machining. This will help you design higher quality machined parts and better use CNC machining to bolster your product development efforts.
Our Design Essentials for CNC Machining covers the following topics:
- Designing cylindrical parts to be turned
- Transition from 3D printing to machining
- Outsourcing to a machine shop
- Cost reduction tips for CNC machine

EYE ON INNOVATION
Virtual reality (VR) may be garnering a lot of media buzz these days, but augmented reality (AR) is gaining traction as a technology that offers practical applications for engineers, designers, and technicians.
Big names are getting involved, too, including Microsoft and Autodesk, which have recently teamed up to pair Microsoft’s HoloLens AR headset with Autodesk’s Fusion 360 engineering design software.
Though still in the formative stages of development, AR-enhanced design software will help developers to visualize designs, view CAD model holograms, and see how new or replacement components and parts might fit on existing products. A recent article in Mechanical Engineering Magazine, for example, showed how AR allowed designers to visualize new motorcycle cladding and a fuel tank cover on an existing bike (see photo).

How does AR work?
Unlike VR, in which you put on glasses or a headset to fully immerse yourself in a virtual world, AR taps into technology to enhance the world around you. Also using glasses or a headset, AR dangles text, graphics, or video into users’ visual fields that describes, or augments, what they are looking at. Continue reading
Reduced cost of development as well as part production can certainly be achieved with industrial 3D printing processes, like selective laser sintering and direct metal laser sintering, but there are a few design rules you need to keep in mind.
Here is DMLS in action, as the machine sinters each layer. This process is repeated layer by layer until the build is complete.
This month’s design tip from Proto Labs discusses:
- Optimizing part design for 3D printing
- Embracing non-traditional design techniques like organic features
- Designing for manufacturability if larger quantities are needed
- Minimizing overhangs and other unfriendly features
- Avoiding “over-tolerancing” your parts
- Factoring in your product’s overall functionality in addition to cost reductions

Join us for a webinar alongside RTP Company as we address common questions related to overmolding. We’ll discuss how to design more durable overmolded parts and what it takes to achieve strong adhesion between your part’s two materials.
Overmolding produces two-material, plastic parts.
The presentation will include the following:
- 12 key overmolding materials
- Design factors that determine quality of flexible-to-rigid bonds
- Methodology used to measure bonding strength
- Differences between low- and high-volume overmolding
TITLE: Overmolding: TPE Multi-Material Molding, Achieving Melt Adhesion
PRESENTER: Steve Brenno, Sr. Product Development Engineer, RTP Company
