LASER WORLD OF PHOTONICS
Ziebura. ‘We are also using open source soſtware at no cost, along with standard electronics and mechanical parts, again at 10 per cent of conventional costs. Te system uses a 140W diode laser with a focus of 250µm and a build volume of 80mm in diameter.’ For its first results with the system for

wider range of users,’ it was stated in the abstract of Ziebura’s presentation. Te centre achieved this by first identifying the most expensive parts of additive systems – namely the laser scanner, optics, mechanical and electronic parts – and replacing them with less costly alternatives. ‘It was [therefore] necessary to develop and find a cheap laser source, a new optical concept, a new process concept, new
electronics and new soſtware, and the system had to be easy to use,’ Ziebura explained. Te centre’s first prototype featuring these
less expensive components was presented at Laser World of Photonics at Fraunhofer ILT’s booth. ‘It’s a diode-based laser SLM concept without a scanner that instead uses an x and y plotter, costing around 10 per cent of the conventional component costs,’ explained
stainless steel, the group was able to reach a density of 99.7 per cent, a minimum resolution of 0.5mm and tensile strengths equal to those produced by conventional SLM systems. With it the group intends SMEs and universities to be able to introduce additive manufacturing to their employees and students, allowing them to experiment with different parameters and materials, and build cheap metal prototypes. Once established in their production chains, SMEs could then make the choice to move on to the more advanced AM systems. In the future, the centre intends to improve
the process parameters of its affordable AM system to decrease build times. ‘We want to develop a machine with stronger motors, as well as to achieve better acceleration and faster build times,’ said Ziebura. ‘We also want to make more materials, such as tool steel and aluminium, possible to process with the system.’
