colorFabb nGen - Cant get it to work properly

Recommended Posts

Been trying to print with colorFabbs nGen. I think the surface looks great but it is very brittle.


I'm printing with an UM2+ .4mm nozzle and am using S3D.

Print speed 45mm/s

Layer height .15mm

Have tried following range:

Temp 220-240° - No difference

Print width .4 - .48mm - No difference

Infill 30-100% - Worse with less infill


Thickness of the thin part is 1.5mm.


I'm trying to print this standing up cus I think the surface look nicer that way. I'm currently only printing the upper part in order to see of it will hold.


The picture shows how it easily breaks, not only between layers but across as well. It acts like an old piece of plastic that gotten hard in the sun. Haven't tried but i reckon that if you drop it on a concrete floor it would go to pieces. The "thinner" piece bends like I would expect.


The scull looks good as do surface of broken piece so I like to think that it's not caused by under extrusion, but now as I'm saying it I realize that I should probably try increasing the flow?

I'm running out of ideas.

Well, I've had it with this one. 3 Rolls down the drain 😞 


Tried all sorts of temperatures, fan speeds, multiplier settings, layer heights, infills. Just can't get it to work.

All my previous printings with PLA (going back for years) are a lot less brittle then the ones I get from this... Sigh...


colorFabbs HT works well for me so I guess I'll stick to that when I need something a bit more resilient. Was looking forward to the lower printing temps on the nGen though.


Enough with the wining already!!


-Just wanted to let you all know.

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
