Why buy a Bukobot?
There are cheaper 3D printers around but this page has some reasons why you should buy a Bukobot. These reasons have been posted not by Deezmaker but by users who have bought one.
Quality Components. The parts provided by Deezmaker for the Bukobot are not selected for lowest price. The materials, electronics and motors are all quality parts. Motors with sufficient torque that you can drive them at a good speed and acceleration without them skipping steps. 3d printing has enough challenges without starting out with poor quality printer components or an out of alignment printer.
Rigidity. Initially I was concerned that because the frame appears to be “free standing” rather than buttressed (e.g., A frame) or braced in the perpendicular direction (e.g. box) that it could lack rigidity. This is not the case. The extruded aluminium beams are very strong. What is not obvious from initially looking at Bukobot design is that the Y-axis has a metal-to-metal join with the main frame. The rigidity of the beams means that the Y-axis beam itself is able to brace the frame in the perpendicular direction. Also as the extruder/carriage only move in the X & Z direction and it is the bed that moves in the Y direction, then there also very few forces on the main frame in the front-back (Y) direction to start with.
Quiet. Vibration in 3d printers are inevitable as the hot end and bed are moving about - especially when doing “zig-zags” involved with sparse in-fill patterns. The Bukobot's extrusion-based frame and plastic guides are very good at dampening those vibrations; whereas printers with laser-cut acrylic, wood or metal bodies can act as a resonating boards and so can be much louder when printing.
Open Source Hardware. Deezmaker's commitment to Open Source Hardware means that you will have access to all the designs for your printer parts and components. This means you can be assured that you can modify, improve or replace them if you need to. If Deezmaker improve the design of a plastic component then it also means you can simply print it out and upgrade your existing printer.
