Large Ultimaker type printer by bwattendorf Oct 12, 2011

Description

This is for a aprox. 4ft by 3ft printer based on the Ultimaker. It has not been made yet and it a thing in progress. It is set up for 4 extruders and also the files have a 2nd normal sized Ultimaker added because there was extra room. (added bonus!!) You can follow our progress on my sons Blog www.rep-up.com you can blame him this was his idea. I hope this will make a nice piece of furniture and I need to figure out a way for my wife to allow it to..

Also any comments, ideas, hate mail, love notes, we would love we are not planing on cutting this for a few weeks.. (hate mail goes to my son..)

Hi bruce, JelleAtProtospace has told me about your project. Im am completely new to 3D printing. But I need one for my college project as the quotes I was getting to get my parts printed was almost the same price as the ultimaker . but my issue was the ultimakers build area wasn't big enough. Would you be able to have a look at my post thingiverse.com/thing:73468 and let me know what you think. I havnt brought anything yet so if you could give me any guidance it would be much appreciated.
Cheers Carl

I see 4 heating elements on the extruder together with my 0.8 mm nozzel and maby Dual intakte of 1.75 mm fillement but x-y engin must powerfull and even geared if you want it to make a print in the same time As the kidbrother ! Like a printer that Can print a plastic chair to sit in :-)

you will need a large laser cutter to make this it will need to be at least 4 ft by 3 ft.
You place stock in the laser cutter that is called out in the file name and press go(or what ever starts the cutter).

There are quite a few snags that will come with a bigger printer. Extrusion speed is probably the largest problem. Ultimaker extruders pass in the order of 10's of grams material per hour. A larger print needs lots of material (to the power of three more!)

On top of that, you add a lot more mass to the system, which will cause extra sag and backlash/flex. The build platfor as it is now is barely suitable for large prints, increasing its size will probably not work as is.

And lastly, make sure your printer will fit through the door! 3 feet may be too wide. At protospace we are dreaming of a large 3d printer that can just fit through the door.
Well I have not increased the extruder size and I was not thinking on doing that. But we have made room for 4 extruders.

The utilimaker does go faster so that will help I plan on the prints taking longer but being able to print larger things is the goal. I do plan on this running for a long time when it does. So the mass will be the increased length of rods for the x y and the increased weight for the build platform. I also hope to reaserch the possable flex on the rods The Z axis is 12mm so I would think this would be not to much flex, and the x y is 8 mm but they both cross each other. I am looking at the hardest ss rods I can find also.

I also do have a door way issue but it can be dismantled when it is every transported and also to get into our printing world..
Could you compensate by using a multiple filaments to feed each extruder? Thicker filaments may work but they would be less flexible and probably harder to find as many color or material options.

Also when a large object is being printed, you run the risk of cracks in your print from thermal shock and uneven cooling. You can solve this with fast printing speed and maybe heating the inside of the unit.

This may be thinking ahead too far but the thought was already thunk. *DONT_KNOW*
Have you increased the smooth rod diameter to deal with the longer spans?
that has been on my mind but no I have not. I have been more thinking about the Z rods I did add holes in the case for a 2nd set but I have not thinking about going to the next size. Good point..
