Onyx/Chopped-Carbon-Fiber 3D printed part used for irrigating suction from a vacuum manipulator to move work pieces.
EOAT is the best solution, but it isn’t perfect
End of Arm Tooling for vacuum manipulators are common in cardboard box assembly shops because vacuums need to securely seal to the product in order to effectively maintain grip. Sometimes, however, EOAT for vacuum manipulators can get snagged on products when product geometry gets complex.
Carbon fiber printed in the perfect geometry.
Markforged was able to print Onyx and Carbon fiber in shapes that are ideal. Heavyweight, traditionally-machined EOAT for these vacuums would get hooked on various features of the product, causing unacceptable and costly slowdowns and stops for production.
Faster, cheaper, and easier to make AND use than aluminum.
As new jobs come in for a package assembly facility, new types of vacuum-heads, end-effectors, and other EOAT must be purchased or manufactured. Both options are costly, and this must be done every new job that couldn’t use EOAT from previous contracts for their vacuum manipulators, due to random factors related to form factor, weight, and geometry.
Hello, World! Matt Jones from Miller 3D here with the newest, exciting developments for the Markforged Metal X!
Today we decided to showcase the newest material that has been released by our partner: H13 Tool Steel.
You can check out the video to see our very first print of H13 Tool Steel in action in this post!!
If you didn’t know already, H13 Tool Steel is a game changer for manufacturing outlets demanding the strongest metal prints for their shops. H13 Tool Steel isn’t only well-known for its incredible strength: it has a very high wear resistance to thermal shock. The concentration of Vanadium in the material helps handle abrasion-focused applications at both high and low temps.
Because H13 also always provides a uniform and high level of machinability, this tool steel is often used for aluminum, zinc, and magnesium die casting.
H13 Tool Steel is also invulnerable to hot cracking, a problematic casting defect that the industry is all-too-familiar with the costly pains of reproduction.
Utilized for designing, planning and documenting 3D projects, CAD or computer-aided design, plays an instrumental role in both 3D printing and 3D scanning processes. More specifically, Capture™ a powerful, integrated, industrial-grade 3D scanner and software system, enables us to scan parts without files or faulty dimensions to recover design data and correct manufacturing errors with CAD.
3D scanned mold. Original CAD files did not accompany the mold
Recently, a mold needed to be repaired to a point where the parts made on it would be acceptable for an end-use application for customers. Miller 3D was asked to help with an application that included a two part injection mold, each about 18” x 18”, but a few challenges were presented to Miller 3Dwhile working on this project.
The first problem was the mold was manufactured by a different company and the second was the absence of CAD models or technical drawings for the molds.
When ‘blueprints’ and supporting files are nowhere to be found, this can create a big problem, however, Miller 3D was given the opportunity to use Capture™ to restore dimensional data and make the accurate corrections to the defective molds.
Pat Harrington, an engineer at Miller 3D explains how the molds were prepared for 3D scanning, “We sprayed the mold with a light white powder spray so that our blue light scanner can capture the data points of the complex surface geometry.”
With a data capture rate of 985,000 points/scan and 0.3 sec per scan, Capture™ produces accurate scans to as little as .034 mm — an impressive, precise 3D inspection process completed by the portable device.
“We took multiple scans of the entire mold and meshed them all together into a final 3D CADmodel,” says Harrington.

Included in multiple scans are automated solid and surface extractions that are featured in PDF reports for engineering teams to analyze for adjustments and corrections. 3D printing garners most of the spotlight, but 3D scanning has the ability to solve application errors, and in return, reduce manufacturing errors, and allow our industry to design from the world around us.
Harrington highlights the importance of the new CAD model generated by Capture™, “This CAD model can be used to help diagnose the issues with the mold in its current state, as well as used as a template for design changes to the mold.” Want to talk more about 3D manufacturing?
