From RBOSE

* Please feel free to contribute to this project

Source

This project has its origins from the famous ["RepRap Mendel"].

Purpose

1. To make a complete redesign to make it easier to source/find parts, cheaper to buy, easier to assembly and better performance.
2. To give RBOSE credit for these improvements
3. To branch off from the sick commercial competition that today host RepRaps further development (Gada Prize)

Brainstorming new names for this project

• RBOS3D

Brainstorming ideas regarding machine

• Possibility to move finished parts off the board
• Only use 2 row pin-headers as connectors (2.54mm) with the use of coding as plugged pins [to reduce cost, decrese complexity and increase availability]
• Pro-tip: If higher current is necessary, use multiple pins
• Use microcontroller that excists from several brands
• Use network interface instead
• Only use one required power supply with wide input voltage (prefairable car voltage 10-18V)
• Possibility to change tool (extruder 0.5mm, 0.1mm nozzle, breakoff, drill, milling, solder, solder-paste, pick-place, paint, laser-cut, scanner, copper paste) http://www.reprap.org/wiki/Development:Workshop_Tools
• Only one single board for electronics
• Possibility to use different belts (using different pulleys)
• Possibility to use only cutted belts [increase availability]
• Extrude with different speed depending complexity of route (the sum of all |angles| in a predefined lenght = speed)
• Extrude faster when making solid than on the edges
• When extruding solid material, use low density in middle, and hard 2mm edges
• Use few different bolts and screws (M4 as smallest part) [increase availability, decrese complexity]
• Maybe use printable belts? ( http://blog.reprap.org/2010/01/high-speed-alternative-to-belts.html )
• Use original lenghts of studding and bars as much as possible [easeir assembly]
• Be able to extrude supportive materials so that you can make more complex objects. (The support should be easily removed e.g by using an acid)
• Optimize plastic parts for least possible print-time (least material used)
• Try to make the complete machine able to make a mobile one
• Investigate if it is beneficial to use a rotating disc instead of the Y axis ( http://www.reprap.org/wiki/Francisco )
• Wireless communication?
• M4 rods?
• Replacebal palstic bearings? (easy to replace, fast to print)

Tips to build professional plastic products

• Make an angular hole and put in one nut
• Make very big threads
• Make coned parts
• Make small plastic holes which can work as nut

Tools used for development

• Blender for mechanical 3d modelling
• KiCad for electronics design
