Companies Push the Boundaries of 3D Printing Composites
Entrepreneurs and existing manufacturers are making 3D printers that automate production of composite parts, and are unique in their design.

Lightweighting is so established it’s now part of marketing for new vehicles. Automakers routinely detail how much less models weigh than their predecessors. General Motors Co., for example, has said a range of its vehicles is anywhere from almost 250 lb (112.5 kg) to 700 lb (315 kg) lighter.
Keeping products clean is becoming a more significant part of manufacturing as standards for cleanliness, deburring, and finish grow more stringent.
From Boeing 787s to new Navy destroyers, fiber-reinforced composites are gaining in use. As production scales up, more-efficient manufacturing remains a focus. One key to that efficiency is tooling for composites. These molds and forms give the final shape to a part, and are often integral to their final curing.
There’s an old saw that if bumblebees were aeronautical engineers they would know they can’t fly. Quite apart from the miracle of their flight, bees also happen to make a lightweight structure of surprising strength, just the sort of thing you’d want if you were building aircraft: honeycomb.
The growing need for nano and micro components in the medical industries is challenging manufacturers to continually improve upon their manufacturing processes and take a scientific approach to injection molding and tooling.
A recent effort by the Norton Advanced Applications Engineering Group demonstrates that for difficult-to-machine materials, grinding can be an economical alternative to other machining processes.
The additive manufacturing revolution is in full stride, flying in aircraft and giving manufacturers a robust tool for design and production
Composites engineers are expanding their craft to build more complex, durable parts at higher production volumes. One way they are achieving this objective is by using infusion-molding processes based on Resin Transfer Molding (RTM) and Vacuum Assisted Resin Transfer Molding (VARTM).
Advanced materials for automotive manufacturing are helping automakers build lighter, more fuel-efficient vehicles.
