MACH 2016 
EOS Electro Optical Systems Ltd (
www.eos.info) will present its growing portfolio of additive-manufacturing machines, peripheral equipment, software and certified powder materials for producing metal and polymer components (Hall 4 Stand 4861).
Suitable for companies considering their first use of additive manufacturing, the new — and modular — M100 DMLS (direct metal laser sintering) machine from Warwick-based EOS houses a 200W fibre laser beam. Moreover, a small ‘spot size’ with high detail resolution enables complex and delicate components to be manufactured, says the company.
With its build volume based on a 100mm-diameter platform, the system can produce small quantities economically — thanks, in part, to its “recoating and exposure” strategy, which reduces non-productive time.
For example, the M100 DMLS can produce about 70 dental crowns and bridges in a single 3hr build. Moreover, a modular interior construction allows the system to be dismantled quickly, facilitating fast material replacement and maintenance.
Currently, two types of material can be processed: EOS CobaltChrome SP2 (CE-certified, CE 0537); and EOS StainlessSteel 316L. EOS Titanium Ti64 will be available shortly.
EOState MeltPool Monitoring — an add-on to the EOS M290 DMLS system — will also feature on the stand, along with a tool that is designed to help companies deliver complete parts traceability, plus automated surveillance and analysis of the melt pool during the build process. EOState MeltPool observes the light emitted by the melt pool.
The key elements are a pair of photo-diodes located on- and off-axis, a camera adapter, a signal amplifier and spectral filters to separate process light from reflected laser light. The associated software offers automatic data error correction and real-time process visualisation and evaluation.
For data analysis, the EOState MeltPool Toolbox visualises data in 2-D or 3-D mappings and operates using three algorithms to obtain different data interpretations.
Finally, EOS will introduce a new metal powder — EOS StainlessSteel CX — for mould and tool manufacture.
