Hi, I'm Teja

Photo of Teja Luckily I got the chance to find my passion in what I do - developing all kinds of software Growing up in the alps addicted me to mountain sports. Additionally I love travelling and getting insights into foreign cultures. Besides my mother tongue German I speak English fluently and am able to communicate in Spanish as well.

DIY Lasercutting Machine

Inspired by several do-it-yourself laser cutters I found on the web I was fond of building my own one. Because most of the projects have limited work space I wanted a machine that can cut at least standard paper sheets. Additionally I wanted the option to use a more powerful laser as well. Therefore I designed a scalable x-y-table with an easy exchangable laser. As the RepRap community already did a great job on building machines with ordinary parts it was just convenient to do so as well. All parts of the laser are either 3d-printable or available in hardware stores, reprap shops or similar. The project sources and a BOM will be released soon.
