ORDBot Hadron - What else do I need for a complete 3D printer? | Robotronics

3D Printer Kits and Components

If you are after an ORDBot 3D printer you have come to the right place but what else besides the 'mechanical platform' do you need to have a complete 3D printer?

There are a lot of options to choose from when building you own 3D printer and it can become a little daunting when you are new to this technology so I though that I would run through some of the options and try and make it a little clearer.

The other items that you will require:-

1) Electronic controller board
I have two options available here both are suitable for driving an ORDBot:-

RAMPS board - the RAMPS board has been around for a long time and is tried and proven technology.

RUMBA board - The RUMBA board is an all-in-one board based on the technology of the RAMPS board but has more expandability than the RAMPS.

2) Cable Set
This is just a set of cables with the header plugs already crimped on, just make life a bit easier than trying to do it yourself.

3) Extruder
I have three options for the extruder:-
Bulldog XL - An all metal precision machined geared extruder suitable for both 1.75mm and 3mm filament.

Bulldog Lite - An all metal precision machined direct drive extruder suitable for 1.75mm filament.

EZStruder cold end kit - a direct drive extruder kit that requires the addition of a stepper motor. Great if you are upgrading.

4) Hot end
I currently have J-Heads to suit 1.75mm and 3mm filament in all three nozzle sizes eg. 0.5mm, 0.4mm, and 0.35mm.

I have the new Merlin hot ends

I also have the all metal Hexagon hot ends

5) Print bed
I have the standard PCB style heating element for the print bed as well as the new dual power aluminium version.

6) Filament
Probably the biggest choice you will have to make is what size filament you want to use, 1.75mm diameter or 3mm diameter. There has been much debate over this choice and there still is. 1.75mm filament is the new kid on the block and some people say that it give better accuracy while others say it makes no difference. An advantage with 1.75mm filament is that it can be driven by less expensive direct drive extruders while 3mm generally requires a more expensive geared extruder. On the other hand 1.75mm filament is generally more expensive than 3mm.

I would suggest that you have a look at the forum to help you decide which will suite you best.

7) Kapton Tape
Kapton tape is high temperature insulating tape. Typically used for insulating the wiring on hot ends and heat beds. I have it in a number of different sizes.

20mm Kapton tape -

Other than that you will need a piece of 3mm glass to sit on top of the heated print bed and a PC power supply of about 400W to power your machine. There are many sites on the web that can tell you how to wire up the PC power supply. Have a look here on the wiki -
