Morgan is designed to be easy to build, easy to use and affordable, with less Vitamins than most – for example:
- 4 x Stepper motors
- 9 x 608z bearings
- 4 x LM8uu
- less than 1m smooth rod
- 12 x M8 nuts etc.
Although the cost of some of these minor vitamins are negligible the idea is not to only to bring down cost, but to lower the overall complexity of the design.
The process of printing with Morgan is exactly the same as any other RepRap. The Firmware takes care of the inverse kinematics that translates X and Y to Theta and Psi
Here are some vitals of the currently released Morgan:
- Configured build volume: 200x200x250 – 10 litre The possible build volume with a half-moon shaped build surface can be up to 30 litre (longest possible printable component could be more than 500mm
- Build price is dependent on the amount of recycled materials used. In the prototype the wood was salvaged from old packing crates, the pipes were recycled from old office furniture, half of the 608 bearings were re-purposed etc. Some of the more expensive components are also optional, like the heated bed, LCD display, SD card reader
- Print quality is not overly dependent on the quality of materials used, excepting possibly the linear elements in the Z-axis
- Print quality is also not highly dependent on the quality of the assembly, as long as the calibration is done according to the instructions. The firmware takes care of the rest.
Morgan is a long way from hitting the $100 material cost because of the excessive cost of some of the exotic vitamins, like the hot-end and electronics. These should be a lot less expensive, and it will be the focus of my research to find the way to make the material cost drop below that target.
Of course kits will never retail at those levels. People need to be paid to do that, and their time is expensive, but makers should have a choice depending on how much they are willing to pay versus how much time they are willing to spend.
A heartfelt thank you to the generous people that donated to Morgan to date. Your contribution, be it time, or money will be worth it when the next disruptive technology is spawned from the 3D tools we are seeding into the world now.
