In the past, Rik Starmans worked as Research scientist at TNO . Here a transpant polygon scanner with multiple laser bundles was developed. Two machines were built. A 3D printer, the Lepus Next Gen and the Argos. TNO tried to commercialize the technology in LDI systems but was unsuccesful. The system was too expensive and unreliable. Rik developed a new system where a single laserdiode is used per transparent prism. The bill of materials for this system is in the order of 300 dollars. The technology is described here . A proof of concept model was built and Rik tried to sell this model via Kickstarter . The campaign was unsuccesful. The technology had to be improved. Salvatore Puglisi developed a Hexastorm cape for the beaglebone called the Firestarter. In the original Hexastorm a FPGA was used but this turned out to be quite expensive and overcomplicated for a single laser diode. The code for the new Firestarter cape is inspired from Ldgraphy . The laser speed is 2.6 MHz. An old technical presentation can be found on Youtube .
Business Case & Technology:
Laser scanning, the process of deflecting a laser beam in a controlled manner, plays an important role in 3D printing, laser engraving and many other modern technologies. Hexastorm uses a transparent instead of a reflective polygon to move a laser beam. This removes the need for an expensive f-theta lens. As a result, the laser scanner can be much smaller and has a lower cost. Hexastorm's new laser scanning technology has four big advantages:
As beachhead market, the printed circuit board market has been selected. We plan to build a device where you can expose a Printed Circuit Board (PCB).
Hexa refers to hexagon. A hexagon is shown in the center of the logo. Storm makes a reference to the rotating prism in a transparent polygon scanner. The name was inspired by the spinning hexagonal cloud pattern on the north pole of Saturn, a Hexastorm. In the current, Hexastorm a quadron and not a hexagon is used.
