CAMX 2017 preview: Thermwood
Thermwood Corp. (Dale, IN, US) is exhibiting its line of 3- and 5-axis CNC routers as well as its new Large Scale Additive Manufacturing (LSAM) systems. LSAM uses a two-step, near-net-shape production process in which the part is first 3D printed, layer by layer, to slightly larger than the final size. It is then trimmed to its final size and shape using a CNC router. The process operates in free space and does not require molds or tooling. Thermwood’s new LSAM is used for the production of tooling, masters, molds, fixtures, patterns and plugs for a variety of industries including aerospace, automotive, boating, foundry and thermoforming. LSAM’s high-wall, overhead gantry features a 10-ft wide, 5-ft high work envelope. Length of the work envelope can be as short as 10 ft but as long as 100 ft or more. LSAM systems include a print gantry and a 5-axis trim gantry. Both gantries operate over the entire table surface. Thermwood’s print gantry features an advanced, Thermwood-developed, vertically mounted Melt Core print head that melts and meters the polymer bead and can process filled thermoplastic composite materials at very high temperatures. Programming and control is provided by LSAM Print 3D, a slicing software solution designed specifically for LSAM that operates within Mastercam, which means it works with any CAD file format compatible with Mastercam. The output is a print file that can be loaded directly into the print gantry control on an LSAM machine and will provide print CNC programs necessary to operate the machine and make the part. No additional software or post-processor is required. Booth Q23.
Wind energy is putting the uncertainty that was the hallmark of this industry in the rearview mirror. Electricity from this renewable resource is cheaper and more competitive than it's ever been — and getting more so. This massive consumer of composite materials has a bright future.
A sheet molding compound renaissance highlights new reinforcements, new fillers, new matrices, new opportunities.
Boeing and Airbus each is generating as much as a 1 million lb of cured and uncured carbon fiber prepreg waste each year from 787 and A350 XWB production. If you include the entire supply chain for these planes, the total is closer to 4 million lb/year. And with the automotive industry poised to consume (and waste) more carbon fiber than ever, recycling of composite materials has become an absolute necessity. The technology is there, but the markets are not. Yet.
