I want to create a RedRap able to replicate itself and able to do good quality items. It has also not to be too big compared to the printing volume. This will probably take a while.
The goals are:
- Create a rotative bed that makes the surface XY of the printer to be less than 150% of the printable space (which is impossible with the actual mendel model)
- The printable area is 300x300x100, but as it's a cilyndre, it's Radio 220mm and Height 100mm
- If possible, a metal piece will remove the finished piece from the bed and clean it
Important to notice that in the central part the volume of MATERIAL that is released in a circle is smaller than in the borders of the circular beds, within the formula:
So, the diference between the volume at the smallest circle and the biggest circle is:
Vb=hπ(R4²-R3²)=hπ(220²-219²)=hπ·439 -> hπ=Vb/439
Vs=hπ=Vb/439 -> 439Vs=Vb -> The smallest circle has 439 times less volume of material than the biggest one!
