Isn't using the Extrusion Multiplier like cheating?

No, the Flow rate or Extrusion multiplier is to compensate for different materials and temperature ranges. Where does the factor come from? Let's say we calibrated our nozzle for work at 200°C with ...

Extrusion adjustment

SHORT ANSWER You're not supposed to do the single-wall perimeter thickness test to calibrate Simplify3D. That screws up the extrusion volume. The correct volume calibration procedure for S3D is: ...

Are self intersecting meshes dirty from a 3D printing perspective?

Self intersecting meshes are considered dirty, yes. The reason you haven't had trouble before is probably that the software you were using was cleaning your mesh for you, behind the scenes. Generally ...

How can I stop the flare out of the bottom layers?

The picture is not very clear so this can be related to either: Overextrusion at the bottom layer (slicer setting) or an incorrect bed leveling (bed to nozzle distance too small), or this could be ...

Why does print fall apart at beginning of top layer?

I doubt this is a printer or filament issue. Rather, I suspect it might be related to how your slicer handles bridging scenarios (which basically is what laying down layers over infill is). You could ...

Can a model change size when using a different filament type?

No, choosing a different filament type will not result in a different size (unless you use PLA that foams on extrusion, it increases size but then again all other dimensions would not fit either as it ...

Can a model change size when using a different filament type?

Of course it can change size... but definitely not in scale you've presented. Filament as same as many other materials can subject something called shrinkage. It depends on physical properties of the ...

Why does print fall apart at beginning of top layer?

The infill percentage is a bit low. Even with infill percentages that are higher than 15% (I use 25%), a single layer on top of infill will not create a good top. It takes at least two and looks ...

How to prevent layer separation, when printing tall vase-like (tube) objects?

The best thing you can do for a large ABS print is to have an enclosure heated to 50C or better. For example, see this, this, this, and other search results.

Is it possible to know which is the correct temperature range and speed for any model?

The first indication for print speed and temperature should be taken from the box the filament comes in. Generally it specifies temperature ranges for the hotend and the heated bed. Sometime, mostly ...

Is there a way to get more horizontal coverage out of "Vase Mode" in Simplify3D?

Version 4 allows you to have multi-process vase mode prints -- do the vertical surfaces in vase mode, then switch over to normal mode for the horizontals. This lets you have the best of both worlds in ...

How to print a 6" wheel in ABS?

If you can, set your slicer to do honeycomb fill. Depending on the weight requirement choose maybe 10% - 20% fill. That ought to do the trick. It won't be solid, but it should be strong enough. ...

Why does print fall apart at beginning of top layer?

Two things. First for a first layer from infill this is not unexpect. This is why you do 3-4 shells with such a sparse infill. Most of the time we also have the first layer at a slower speed. Often ...

Isn't using the Extrusion Multiplier like cheating?

That's one way to look at it, I guess. I think a more accurate way is to consider it an "ad-hoc calibration" where one realizes that their printer isn't extruding enough/too much and the EM adjusts ...
