How can I solve too thin deposited wires?

Recommended Posts

Hi guys!

I'm a beginner in the 3D printing universe and I really struggle to obtain my first good prints with my new Ultimaker Original +.

I think my problem is that the extruded filament is far too thin, like I'm having sort of under-extrusion but at a constant rate. I managed to obtain a regular plastic deposition, but the deposited wires are really really thin. I tried to mesure this width with a digital caliper but it's too thin and too flat to measure anything.

I've tried to print a first layer test square with the silver metallic PLA that is provided with the printer, with the recommended settings first. I obtained this one layer part with unjoined extruded wires, as it can be seen on the picture. I assume these gaps between the wires are not normal as I selected "solid fill", am I right ?

To solve this issue, I've tried first to increase the flow rate to 125% without noticable improvement, and then to increase the nozzle temperature from the default 200°C to 215°C while reducing the print speed to 40 m/s as recommended by many experienced users, without success again. All this after many nozzle cleanings following the Atomic method.

What else could I try to solve this issue ? Since my machine is new, I assume the coupler is ok, as well as the bowden tube. I also checked that the filament moves on when I rotate the feeder wheel and that it's slightly marked by the drive wheel.

Thanks in advance for your expert feedback!

Elie

      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.
