TIPS WITH TONY: Machining Capabilities for High Performance Parts

Do you know how machining a part from titanium can improve its functionality and performance? How about using key inserts for improved durability to your part. Here are few capabilities and design options to keep in mind for your next machined part.

Titanium machined parts.

Titanium
Let’s start off with some big news. Previously, we only offered titanium for 3D-printed parts, but it’s now available to customers for machined parts. And, if that wasn’t enough to catch your attention, how does titanium machined parts in as fast as three days sound?

Titanium is extremely strong and boasts a high strength-to-weight ratio. It also has excellent corrosion resistance, high operating temperatures (up to 1,000°F) and is nontoxic.

Titanium has range of applications due to its advanced material properties. Frequently, you’ll find titanium parts in the aerospace, medical, military and marine industries. More specifically, it’s used for parts like rotors, compressor blades, hydraulic systems, surgical equipment, dental and orthopedic implants as well as in military aircrafts due to excellent ballistic characteristics.

The only drawback is the cost of the raw material. It’s more expensive than steel. For this reason, most manufacturers don’t hold a lot of inventory, but that isn’t the case at Proto Labs. We maintain a level of inventory that allows for on-demand milling and turning of titanium parts

Key insert for added durability.

Key Inserts
Key inserts are steel threaded inserts commonly used in aluminum parts for added durability. Note that these are different from standard coil inserts as they have an added keyway with a tab inserted to prevent twisting under extreme load.

Key inserts are primarily used by the aerospace and military industries following the military standard of MS51835B. We offer eight thread sizes ranging from #8-32 to ½-13. For a full list, visit our threading page and click the key inserts tab.

WHITE PAPER: Data, Digital Threads and Industry 4.0

By now, you’ve probably come across the term Industry 4.0. And yes, it can seem like just another term in the buzzword dictionary, but many of the world’s leading technology and manufacturing companies — including yours truly — rely on it, every day. It’s how we take your 3D CAD model and turn it into a finished part faster than anyone else.

Download our free white paper to learn how companies are accelerating product development with software and analytics.

It’s important to note that Industry 4.0 isn’t only about 3D printing and new manufacturing processes. Rather, it’s about connecting automated front-end software with back-end hardware for more informed decision-making and efficient execution.

We refer to the link between each of the processes as the digital thread, which is made possible by software and technology.

Download the free white paper to learn how your business can tap into the power of the digital thread and join the next industrial revolution.

THE SHORT LIST: 4 New Capabilities at Proto Labs

The crew at Protoworks (our R&D program) has been busy. Every day they’re pushing the boundaries to advance new rapid manufacturing processes and materials and expand your design possibilities.

We just rolled out a few new capabilities that we’re excited to share.

2 is better than 1: Overmolding

Overmolding expands on our injection molding offering. At Proto Labs, it’s a multi-step process where we mold a substrate part and place it into a second mold, which then molds another material onto the substrate. It’s called pick-n-place molding.

Overmolding can aid in dampening vibration, improving grip as well as two-color aesthetics. We are still in the beta testing phase of our overmolding process, but it’s open to everyone.

Visit our overmolding page for design guidelines or to submit a request for parts.

Extra-strength machined parts: titanium

You asked. We listened. Our CNC machines can now mill and turn parts from titanium. With an excellent strength-to-weight ratio and corrosion resistance, titanium is most suitable for applications in aerospace, medical and other industries where high performance is critical.

WEBINAR: Designing for Stereolithography

3D printing deserves an in-depth look. Whether it’s determining the right 3D printing process, selecting the right material or understanding design considerations, there’s a lot to think about.

Eric Utley, 3D printing application engineer

We’re kicking off a series of 3D printing webinars with each session focusing on one process so we can really take a close look at what makes each process unique.

Eric Utley, 3D printing application engineer at Proto Labs, will share:

  • An overview of stereolithography
  • Material options and recommended applications
  • Design tips to improve surface finish, reduce cost and other benefits

After the presentation, you’ll be able to ask Eric any questions you have in an open Q&A session.

EYE ON INNOVATION: 3D Printer Boldly Goes Where No Printer Has Gone Before

3D printing continues to break the bonds of traditional manufacturing methods. Now, a private company collaborating with NASA is breaking Earth’s bonds by taking 3D printing into space.

In April, at the International Space Station, NASA successfully tested a zero-gravity 3D printer that’s been in development for several years from California-based Made in Space.

NASA found that the specially designed, zero-gravity 3D printer could in fact manufacture parts and tools on-site and on-demand. As NASA points out on its website, this on-site, in-orbit manufacturing ability would be a huge benefit for long-term, deep-space missions with restrictions on weight and room for cargo. The tests on board the space station included successfully printing items such as wrenches. So far, more than 25 objects have been produced.

As Gizmag.com reports, the zero-gravity printer is an extrusion printer that, like other 3D printers, builds up layers of hot liquefied ABS thermoplastic to create an object. However, a number of factors had to be taken into consideration for designing it to work in a zero-gravity environment. Components that might previously have been partly held in place by gravity had to be redesigned, thermal processes had to be recalculated and the layering process had to be reconsidered. The printing functions were then all integrated into what is called the Microgravity Science Glovebox (MSG), part of an overall platform dubbed the Additive Manufacturing Facility (AMF).

As a spokesman for Made in Space says in a promotional video: “The goal…is pretty simple, but audacious…to develop the necessary technologies to allow humanity to move beyond Earth and live on other planets.”

Meanwhile, more down-to-earth considerations include, as Wonderfulengineering.com reports, Made in Space’s announcement this week that it is “going commercial and inviting the public [to purchase parts] made in the unique presence of zero gravity.”
