Project Description

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.

Project Goals


The goals are:
- Create a rotative bed that doesn't occupy more than the 150% on the plane XY 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

Working Notes.

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:
R4>R3>R2>R1

Vs=hπ(R2²-R1²)
Vb=hπ(R4²-R3²)

So, the diference between the volume at the smallest circle and the biggest circle is:

R4-R3=R2-R1=1 mm
Vs=hπ(R2²-R1²)=hπ·1=hπ
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!
