Does color changing PLA require a hardened nozzle?

I've seen comments about glow-in-the-dark filament being abrasive and would damage a bronze nozzle so a hardened nozzle is recommended. Is the same true for filament that changes colour when warm (for example when held in your hands)?

Can the filament tube be outside of the nozzle?

I bought a few new nozzles expecting them to come with that little tube that comes out of the nozzle. They didn't come with them after all, so I tried to reuse the tube I originally had in the printer. Turns out my old tube is 4mm OD and 2mm ID, but…

Getting worse quality prints on 0.05 mm than on 0.10 mm layer height on Prusa i3 MK3

I have a new Prusa i3 MK3 and I have noticed that my prints consistently turn out worse on 0.05 mm layer heights than on 0.10 mm. The edges of the 0.05 mm prints turn out rough and sometimes stringy. Seems similar to a retraction problem but I…

Triangulation adapted to curvature

I don't know whether this belongs here (where most of the questions appear to be about hardware) or on Math or on Blender (though I've never used Blender). All of the designs that I've published so far consist of grids of bent ‘rods’, and in most of…

Does moving the z-endstop upwards affect the maximum height of the printable object?

As moving the endstop upwards reduces the range of the z-axis, I was wondering whether it reduces the maximum height of the printable object, by the distance the endstop was moved. Or is this somehow (to a certain extent) beeing…

Makerbot Smart extruder+ heat block and nozzle question

I am looking for information on the smart extruder+ heat block and nozzle? I have looked online and from several forums come to the conclusion it is either a MK10 or MK11 assembly. Can anyone shed some details on the heat block and nozzles.

Hold torque during pause to change filament

How can I achieve keeping the motors active during pause to avoid moving their position during filament changes? I have changed the filament during some prints to change the color or to change the a newer spool, but sometimes the X axis is moved…

What are the appropriate ranges of gear ratios for 1.75 mm and 3 mm filament extruders?

Most 3 mm (mostly are actually 2.85 mm) filament extruders have some kind of gear reduction. Many 1.75 mm extruders are direct-drive / ungeared but some do use gears. What kind of reduction ratios are suitable or optimal?

What are the limiting factors when trying to print flexible filaments with a Bowden extruder setup?

Other than the most obvious issue with the filament kinking in the tube, what other issues could arise when trying to print flexibles (i.e. TPU/TPE, Nylon, etc.) with a Bowden style extruder setup? Can the kinking issue be alleviated by a…

Why does MakerBot Replicator heat the extruder and platform separately?

I am using a MakerBot Replicator 2x, and when it is heating the platform and extruder, it begins by heating the platform, and then after that is at 110C it goes on to heat the left extruder to 230C. Does anyone know why it does this, since it has…
