To build a regular 3D printer we need:

Part I: The Frame

Part II: The Y-Axis

Part III: The X-Axis

Part IV: The Z-Axis

Part V: The Extruder

Part VI: The Build Platform

Part VII: The Electronics

Part VIII: The First Print

Therefore, first we need to figure out the cost of the cover. We are using polypropylene for the frame and some parts in the 3d printer. It is plastic material that will not melt under the temperature of 204 C degree. According to this site, http://www.eplastics.com/Polypropylene_Sheet, the plastic that I want to get for the cover will cost me around $21.36 x 4= $85.44

 

these are the information about material:
0.250″ x 24″ x 48″ Natural Polypropylene Stress Relieved Sheet
Quantity
Price each
3 – 9   $21.36

 

I am also going to use technique of paper shredder to make the cutter. It is going to be around $50.

Touch screen is also needed. For the feature and setting set up functions.  Touch screen will cost around $100.
We need fabric recycle machine and textile mill and sewing machine inside the printer. Therefore, they need to be in a mini size. Recycle fabric machine is $200. A smaller textile mill machine cost us around $190. Mini sewing machine is $20. I make them much small and fit them all into the frame, and I need to make sure they operate nicely. I need for invention, because I might do numerous tests, and I might fail some.

 

It will total cost me $646.44.

I will prepare $1291  extra just in case I fail.

Therefore, I need at least $2000 for funding to start the invention.
