As additive manufacturing emerges from a long infancy, the industry is grappling with a key challenge: A file format and design tools from the 20th century are being asked to do 21st century jobs.

The challenges to manufacturing as it evolves into the 21st century are now familiar, and impact how metrology must contribute. Manufacturers face uncertain production volumes with roller-coaster demand, shorter production runs and faster product development cycles. Automation, while alluring as a way to reduce cost, needs to adjust.

Modern manufacturing is rapidly adopting model-based definition (MBD). When employing an MBD strategy, the CAD model becomes more than the nominal to which all parts are measured and inspected against. MBD keeps the all-important digital thread intact—from design to manufacturing to inspection and quality reporting.

Until the middle of 2010, first-tier subcontract machinist, JJ Churchill, could produce turbine blades only if they had their fir-tree root-forms preground elsewhere, or if they were subsequently added by another subcontractor. No longer is this the case.

Anyone who’s worked with wind turbine blades or just seen one up close can attest to the massive size of these clean-energy workhorses. Ever thought about what happens to that costly, high-tech material once the blade reaches the end of its lifespan in 20 years or so?

Infinite Material Solutions LLC announced the launch of a water-soluble 3D printing support material called AquaSys® 180.

3D Systems announced enhancements to its reverse engineering software products.

Lungs, hearts, tumor-filled skulls, brains, livers, kidneys, and rib cages, are packed into shelves at the 3D Anatomic Modeling Laboratory at Mayo Clinic.

In the cornfields of southern Indiana, Thermwood Corp. is making unique large-scale additive manufacturing (LSAM) equipment. LSAM machines produce large- to very-large-sized components from reinforced thermoplastic composite materials, creating industrial tooling, masters, patterns, molds and production fixtures used in the aerospace, automotive, foundry, and marine industries.

ExOne Co. said it was launching its updated Quick Ship metal 3D printing services, featuring a new digital quoting tool and materials.
