CLEARLY! UNDER CONSTRUCTION AT THIS POINT

A little patience while its being completed

This is the Page for my development of the 3D printers I use daily and after 3 years I finally feel they are good enough to share.

The printers are names 3dOne and their version numbers are a very original P1, P2, P3, P4, and P5. At this time I am on version P5 and while my printers have been very good for a while this one just printed beautifully from the start.

I may post this project on my own site at www.3done.co.za however the printer should be shared and the more people that build one the more I will be encouraged to improve the design.

My printer design in highly customisable to suit your requirements and should provide you with a easy to build and maintain printer that will put many store bought printers to shame. Even after being built the open frame nature of the design means you can modify it to change or adjust dimensions.

Construction

The 3dOne printers are constructed from a aluminum frame with printed parts holding part in-place. Printer P2 was built on a 19mm frame and all subsequent machine are built on 25mm square tube. 19mm is suitable for a small printer in the 20x20x10 range and this is actually sufficient for many prints, the 25mm framed machines are built to print 30x30x30 and can scale a bit bigger than that.

The construction is one made to be from parts that are easy to find. if you have a cube structure you can build this printer into it. to change the size of the printer can be done by simply increasing the length of the parts in the dimension you want to increase it. It means this is a printer that can be built to your requirements.

Tools you will need

• Digital vernier caliper
• Screw drivers (flat star etc)
• Ceramic or plastic screw driver for adjusting the stepper drivers (don't skimp one slip will cost you your arduino mega)
• Dremel or similar tool ( cutting, grinding, cleaning, engraving)
• You will need a saw to cut aluminum (I used to use a hack saw but have since got a cheap miter saw and can highly recommend it)

Basic Parts list

• You will need the printed parts for this printer to facilitate assembly. These depend on the printer you are building. Certain parts are specific to the the 19mm or 25mm frame and others can be used on both.
• Vitamins
  • I base my machines on RAMPS1.4 but there is no reason other controllers wont work
  • You will need between 4 and 6 stepper motors
    • 4 for the X,Y,Z and E
    • 1 additional required for 2nd extruder.
    • 1 additional highly recommended 2nd Z axis drive.
  • 8mm stainless steel or bearing grade shaft (stainless works fine but does wear a little over time)
  • Pulleys required (GT2 or GT2.5)
    • 2x 8mm shaft
    • 2x 5mm (for stepper motor so match to that)
    • 1x printed pulley for Y axis (can use another one as you do on the 8mm shaft I use the bigger one for additional torque to move the x axis)

Some basic tips

• That dremel tool I mentioned engraving, use it to engrave the size of your nozzles onto them. 0,4 0,3 etc or you will end up with a box full of them with no idea what size they are.
