Ultimaker 1, filling not correctly

Recommended Posts

I've just starting to print with my Ultimaker 2.0,

as an upgrade for our Ultimaker 1.0 (Bought at the end of last summer).

So I started printing side by side, when I noticed that the Ultimaker 1 has a terrible filling.

The filling of the Ultimaker 2 is 100% but the Ultimaker 1 is leavings gaps in the print.

What can I do to make the filling of the Ultimaker 1 as good as the one of the Ultimaker 2?

That does not look like a 100% infill indeed.

Are you sure your setting is at 100%? looks like 50

When using cura? it should be on the basic tab -> Fill density (%) 100.

Otherwise it is under-extrusion, In the bottom of the basic tab, check if flow is at 100% and the diameter around 2.85.

If that is correct, check/clean your nozzle and feeder.

Hartelijk bedankt voor je antwoord :)

Al the settings are correct, just as above.

It can be the nozzle, I've had a overheating problem a few months ago. (Wiring problem, to much pressure on the cable)

But the weird part is that if printing at an angle the print will look better than the print of the UM2.

The machine is further in perfectly working order, this is the only thing that is bothering me.

I'm currently printing at 230 degrees, so that should be fine.

Walls are looking great especially when I print the same stl file side by side.

When printing under an angle the UM1 preforms even better than the UM2.

Blue pla: UM2

Grey pla: UM1

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
