By Marcin Goettig WARSAW (Reuters) – Polish 3D printer maker Zortrax, expanding fast after a landmark U.S. order, is pressing ahead with fundraising plans that could include a flotation and that dovetail with government ambitions to create a hi-tech economy. Founded as recently as December but already growing at a breakneck pace, Zortrax is on schedule to complete the order from tech giant Dell for 5,000 of its M200 desktop printers by year-end, Chief Executive Rafal Tomasiak told Reuters in an interview. Zortrax’s segment of the 3D printer market has been growing by several hundred percent each year and “we are growing at an analogous pace,” Tomasiak said.
