Open Rapid Unlimited Geometry Destroyable mold molding and casting



If you like what you see, don't just copy our technology, join SENSORICA. It is in your best interest! Here's why



Description

OpenRUGDMMAC,  pronounced "open rugged-mac", is essentially a successor to 3d printing.  It uses additive combined with subtractive 
manufacturing techniques to overcome the fundamental weaknesses of both, to provide what may truly be an extremely enabling revolution empowering people to produce useful objects and equipment. The system also produces highly accurate, disintegratable molds of truly almost any desired shape, with none of the limits imposed by machining, or 3d printing in their usual form.  See more in the short version doc, dig deeper in the long version doc. 

Goals : develop the hardware (robot, including an auto tool change high accuracy router) and the software  

Background: This project is the direct outgrowth of two years of experience in fablabs and makerspaces around the world, full time.  Including 4 months at open source ecology.

Participants

[list members actively involved and all other stakeholders]
[This list will be replaced with a UI/script which will automatically pull info from the activity log, and display members
involved and their relative contribution. See infrastructure activity cluster for more on infrastructure development.]

Tools, activities, and processes

[provide information about technological tools use in this project, database, meeting places, ... Ex: folders in Google docs, Diigo link and tag used, project management, etc. ]

Skills and resources needed

  • Software engineering: Python. Process planning from the high level algorithm stage down to a machine agnostic language, from therr to gcode for Emc2.  
  • Electronics engineering - may be a need to design a powerful sine wave oscillator of 1.7 mhz or 20-40 khz, of a kilowatt or more, to drive an ultrasonic transducer.
A good micrometer, digital calipers, and hole gauge, a small selection of small end mills from quarter inch to 1/32, carbide, and some v point ones, some lolipop ones. Oscilloscope, good Vom, good solddring iron. 
Powders of graphite from ten to 100 microns diameter, ideally a selection. Low viscosity high strength wax, silica colloid binder, candidate powders such as hexamine and cross linked polystyrene or styrene monomer for the support material. Some water soluble wax and acrylic binder for block molding.
