FDM 3D printer BiBONE by U-Design / not RepRap
I would like to present a printer of my construction, which I called BiBONE [Bigger is Better 
] At first glance, similar in construction to the RepRap Prusa Mendel, but this is only appearances. Unlike Prusa's flaccid design (M8 rods) BiBONE has a frame made of M12 and M10 rods. to which linear guides fi12. I designed all the plastic parts from scratch. Z-axis motors placed at the bottom of the frame (Nema17), XY-axis motors more powerful, in a Nema23 housing. I am successively posting the files on Thingiverse, where they will be available for download for use "for your own purposes, no sale", licence: Non-Commercial - No Derivatives.
Instructions for assembling the printer as of today based on photos taken of the finished machine:

I was inspired by the Prusa Mendel model, but unfortunately it has its rather serious flaws. When designing the BiBONE, I improved everything that I found uncool in the Prusa: the rigidity of the frame, the possibility of fitting more powerful motors, moving the Z motors downwards, a different way of running the toothed belts, a different way of fixing the Z axis linear rods
The printer was designed to work with a 300x270x300 work area, but nothing prevents you from assembling a smaller but even more rigid version. I am currently assembling a miniBiBONE version with a work area of 240x200x200

Printing your own parts is something. Plastic parts created in another reprap? What are the costs of the overall design? [Read more]
Extra :D and what plastics can your printer print with ? [Read more]
Yes, I printed the plastics on my smaller Prusa. Printing standard ABS/PLA (that's what I tested on). The head can be heated up to 260 degrees. The cost of the overall design depends on many factors: -... [Read more]
In what program can you design the solids? You can buy a set of plastics for the reprap for 300£.Printing is that expensive or is it some kind of their markup? [Read more]
Printing is cheap, the cost of ABS is £35-60/kg. The weight of the Mendel Prusa Reprap components is about 450 grams. The main thing you pay for is the time taken to print, which, depending on your printer,... [Read more]
Can the author explain how the head of this printer works? I think some sort of pinion takes the plastic, drags it on, where it is heated by the wire windings? and pushed out through the nozzles? That's... [Read more]
The whole extruder (as it is referred to) is a simple device. The motor, via a gearbox, drives the main screw that pushes the ABS plastic (in the wire). The screw is knurled so that there is no slippage.... [Read more]
How is the solid converted to layers? I see some uC in there.Is the code publicly available in hex form or better still, in a higher level language or maybe only to be bought from the on-board comput... [Read more]
The code is generated by a cutting program called a slicer. The most popular are Slic3r and Skeingorge. They convert a solid file in STL format into gcode. Firmware for the atmega is available on the... [Read more]
Another question about the head. Does the gearbox have to be the same as the original or is it all set via soft start? Now a purely theoretical question, can the plastic parts holding the threaded rods... [Read more]
The gear ratio can be anything you want. In the firmware you set the number of steps per mm according to a given formula (you specify the gear ratio). The plywood parts will be stronger than the printed... [Read more]
Hello I am thinking of buying such a printer. I won't build one myself as far as mechanics I have no problems with, I can't cope with electrics and electronics. I found something like this in... [Read more]
Looking at these photos, the construction leaves a lot to be desired - supposedly a sealed box, but all welded from thin, bent sheet metal, I would be wary of buying such a printer. Soldering is the... [Read more]
Thanks for your reply Well after the calculation it doesn't come out so bad anymore. I'll have to ask a colleague if he can help me with the electronic/electrical side. But all in all, I can slowly... [Read more]
I've made a topic like this "First Steps" on my forum - lots of linked content there, so let me paste a direct link - I think it will help many people familiarise themselves with the topic http://www.mojreprap.pl/board/viewtopic.php?f=12&t=192 A... [Read more]
