PRODUCT SHOWCASE Industrial-Scale 3D Printing of High-Strength Carbon Fibre Parts Markforged, represented in Australia by Emona Instruments, has announced the industry’s most powerful fibre-composite 3D printer, the Mark X. The Mark X’s high strength carbon fibre 3D printed parts will be in demand for both prototyping and manufacturing scale parts printing for mining, manufacturing, renewables, medical prosthetics and electronics/telecommunications applications. In addition to the large print volume of 330mm x 250mm x 200mm (X, Y, Z), it has in-process laser inspection as well as a fine (50 micron) surface finish to make this one of the most powerful, precise, and unique 3D printers on the market today. “We have taken a different path from most of the 3D printing industry with innovation that will create a new bottom line benefit for many manufacturers” says Greg Mark, CEO and founder. “We already had success with the breakthrough strength and light weight of continuous carbon fibre in our Mark Two printer – now we have added in-process inspection for exact dimensional accuracy, high resolution beautiful surface finish, and scale to open entirely new segments of the industry to efficiencies of what printing can accomplish.” Contact: Emona Instruments Pty Ltd PO Box 15, Camperdown NSW 1450 Tel: (02) 9519 3933 Fax: (02) 9550 1378 Web: www.emona.com.au PCBCart’s aluminium-backed PCBs: heat dissipation and light weight Aluminium PCBs contain a dielectric layer between aluminium base and copper foil. The dielectric layer is thermally conductive but electrically insulating, so that it offers better heat dissipation than conventional PCBs. Furthermore, the dielectric layer has such a low thickness that aluminium PCBs are light in weight, compatible with the miniature requirements of modern electronic products. Aluminium PCBs are largely used for LEDs, power equipment and automotive systems. For better heat dissipation, there are FR4 and through-hole aluminium PCBs. Minimum drill diameter can be as small as 8mil and minimum annular ring, 4mil. For high-frequency and high-density PCBs, multi-layer aluminium PCBs can be made with up to 24 layers and a minimum trace or spacing as small as 4mil. PCBCart can make aluminium PCBs with board thickness from 0.8mm to 5.0mm and a maximum size of Contact: 610 × 610mm; surface PCBCart finish encompassing Floor 3rd/4th, Building #1, NO.163 HASL, lead-free HASL Wu Chang Road, Yu Hang District, Hangzhou, and ENIG and various China 310023 Tel: +86 571 87013819 solder mask colours.

ER2223 is a black, very high temperature, stable epoxy resin with a wide operating temperature range of -40 to 180°C and is designed to meet automotive under-bonnet requirements. ER2224 is a thermally-conductive epoxy resin system, featuring an improved method of cure, high thermal conductivity and good thermal cycling performance. It is also suited to automotive applications and LED lighting units. ER4002 is a flame-retardant epoxy resin with excellent electrical and high temperature performance and an operating temperature range of -40 to +150°C. The resin is suitable for the encapsulation of delicate electronic and electrical components and features low mixing viscosity and good flow characteristics. New polyurethane resin systems include UR5638, a tough, low exotherm resin, which provides a clear, transparent finish. UR5638 is particularly suitable for encapsulation of larger LED Contact: lighting units. HK Wentworth UR5639 is a low viscosity, 3/98 Old Pittwater Rd, Brookvale 2100 low hardness resin, trans- Tel: (02) 9938 1566 Fax: (02) 9938 1467 parent with a high level of Web: www.electrolube.com.au flexibility.
