Why do some models appear broken in slicing software?

In my slicing software (Slic3r) some of the vertices/walls of my model seem to have disappeared, so that the inside of the model - which should be solid - is visible, while the surface appears as a thin shell. Why does this happen? Is it still safe…

Slic3r - Can I add new infill patterns?

Slic3r comes with a handful of infill patterns/algorithms, including Rectilinear, Hexagon, 3D Hexagon, Concentric, and Hilbert Curve. Are there any patterns/algorithms already made and available that I can add to Slic3r? If so, how can I add them…

slic3r: Can I vary the infill percentage for different heights of my model?

How can I vary the infill percentage for different layer heights of my model? Context: The bottom part of my model needs about 20% infill. The geometry of the top part of the model (mostly cones of various sizes) prints well with 0% infill and is…

How can I calculate volumetric speed for Slic3r auto speed?

I have noticed that Slic3r offers a speed setting called "auto speed" meant to give a constant filament pressure at the extruder, which I believe could eliminate filament grinding issues at higher printing speeds. According to the tooltip in…

G-Code for resetting to 100% speed

I had problems printing parts and I figured out that my children have turned the knob of my Prusa i3 MK3 and set the printing speed to 112%. Since I'm not experimenting much yet, I'm not printing at different speeds than the original speed. I wonder…

Trouble printing small thin pole

3D-printing newbie here. I have a Geeetech's Prusa i3 mk2 B. I'm trying to print this: https://www.thingiverse.com/thing:1358311 That's a mold, with 2 external parts and a core. The exterior prints wonderful. But the core is too messy. Take a look…

Slic3r: How can I automatically modify the STL filename?

When generating STL files with slic3r I would like to automatically prefix the filename with strings such as PLA or PET before uploading to my printer. How can I specify this in the filament settings?

What is wrong with my "disable sensor" gcode?

I have a spool of translucent PLA filament that doesn't work well with the filament sensor on my Prusa i3 MK3. The translucency trips up the sensor, making it think the filament ran out. I thought I'd create a filament profile in Slic3r and disable…

Getting started: shell passes not fusing in x/y, and a slanted wavy pattern on vertical walls

I'm trying to find the main reason(s) for the imperfections I'm seeing in printouts from my printer. It is an I3 clone from Folger Tech. I got this printer from a friend who used it to print a larger one, so the mechanics are apparently fine to the…

Cooling for big layers

There is an option in Slic3r to disable cooling for layers that take more than n seconds. What would be the disadvantages of having cooling on big layers ?

Skipping Y-steps, only when using Ultimaker Cura

In order to find out why my printer sometimes skips Y-steps (always in the same direction) only in Ultimaker Cura, I am digging into the G-code to understand the problem better. However, thousands of lines of G-code are hard to analyze. I am using…

First (bottom) layer has gaps

First off - I'm rather new to this and I might be on the wrong track altogether... I'm printing PLA using a simple DIY XYZ printer with a direct-driven extruder, 0.3 mm nozzle, 0.2 mm layer heights, using Slic3r. I've tried to calibrate the bed as…

How can I set the 1st layer after a raft in Slic3r to print at 1st layer speed

When you add a raft in Slic3r, the first layer of the raft prints at the first layer speed. After the raft is finished, the first layer of the print prints at the standard speed. How can I make the first layer of the actual print slow down to the…

Ender 3 severe under-extrusion

I've been using my Ender 3 for about four months now and it's been working wonderfully. The print quality is amazing and all the prints are very strong. Then about three weeks ago, my entire system crashed while Ultimaker Cura was open and it lost…

20x20x20 calibration cube size change after switching filament

I used to print with PLA and everything in my printer was calibrated. But I got a new type of filament called Poly Hybrid from a friend of mine. When I print a 20 mm cube, the x and y axes are fine but z axis in cube is about 18 mm. Should I…
