The incredible Peachy Printer: $100, 3D Printer & Scanner with an incredible technology
These guys want to create the first $100 3Dprinter (that actually sports also Scannig features).
The project is still in it’s infancy but it’s so cool that was hyper funded on kickstarter. Cool stuff:
See how it works:
The peachy printer is a Photolithographic printer. That means it uses a controlled beam of light to cure light sensitive resin into hard objects. The peachy moves a laser beam along the X and Y axes to create the shape of the object, while using a drip system to control the level of the resin on the Z axis which determines the height of the object.
The software we wrote […] takes the data from that 3D model and translates it into an audio waveform. It then plays the audio file out to the printer through the headphone jack in your computer. This waveform drives a pair of electro magnetic mirrors. The higher the volume, the higher the voltage, the more the mirrors move. The purpose of these mirrors is to reflect and control the path of the laser beam. By using the audio waveform generated from the 3D model data to drive the mirrors, we are able to get the laser beam to draw out the shape of the object. That’s takes care of the X and Y axes.
How does the 3D Scanner work?
When combined with a camera, the Peachy Printer also functions as a 3D scanner! The Peachy repeats a back and forth laser pattern that simulates a line laser. This illuminates the profile of the object you are scanning. Your video camera, webcam, or DSLR will capture this happening while you rotate the object a full 360 degrees. The software we wrote in Blender then searches through each pixel in every frame looking for the point where the laser is hitting the object. Next it calculates the distance of those pixels from the objects rotational centre and plots the points and mesh accordingly in 3D space. You now have a 3D model of the real life object you scanned.
