NOSE Bioprinter mod question  

Active Member

Hi everyone, 

I'm a biologist working on stem cell development - full disclosure, I know next to nothing about 3D printing but am very down to learn... 

I am in the process of building a Prusa i3 MK3s to adapt to make the bioprinter reported here:

I'm in the process of building the frame and had a question. Do you think it is worth building the kit fully and testing it with the plastic extruder, and then go on to mod the printer? Or would you recommend not fitting the extruder and just proceeding with the bioprint build. 

Please forgive my ignorance - any and all opinions and thoughts welcome. 

P.S. If anyone from Prusa reads this - your kit is kind of amazing. I've never come across such well constructed instructions and easy to navigate kit. Very well done!

Hi A-Khan-4,

I would suggest building the printer as a plastic printer first and ensuring everything works as expected, before modifying it. 

I would also highly recommend lubricating the linear bearings during assembly, rather than waiting for a maintenance breakdown...

I try to make safe suggestions,You should understand the context and ensure you are happy that they are safe before attempting to apply my suggestions, what you do, is YOUR responsibility. Location Halifax UK...

Thanks for taking the time to respond - I will do as you say. Including lubricating the bearings! 

Best wishes

On lubrication - you will get a potful of suggestions on what to use.

This is a light duty application, and pretty much anything is better than nothing.

If you use SuperLube, look at a lubricator cap like this:

Of course, to print one you have to have a 3D printer working. Then it is too late to lubricate during assembly.

Maybe, just this time, have someone print one for you.
