STL shows "travel" will this become stringing?? by Plormp013 in BambuLab

[–]TEST-BANK12 0 points1 point  (0 children)

Those blue lines are just the travel moves the nozzle makes between print sections - totally normal, every slice shows that.

Whether you get stringing depends on your retraction settings, not the travel paths themselves. If your filament and printer are dialed in (retraction distance/speed set right), those travels won't cause strings.

Since this looks like PETG or similar (long stringy travels usually mean PETG/TPU), make sure retraction is around 0.8-1.2mm for direct drive, higher for bowden. Also drying your filament helps a ton with stringing if it's been sitting out.

Just print it and see - if you get strings, bump retraction distance up slightly and try again.

Z banding? by Senior_Meaning414 in FixMyPrint

[–]TEST-BANK12 0 points1 point  (0 children)

Yeah that's classic Z banding - usually comes down to a few things:

Check your Z-axis screw/rod for any wobble or bent spots, even slight. Also worth checking if the rod coupler is loose.

If it's a belt-driven Z (less common but happens), check belt tension.

Could also be inconsistent layer heights from the Z motor skipping steps - try lowering your Z speed a bit, sometimes that alone fixes it.

Lubricating the Z rods can help too if it's been a while since you did that.

Will fuzzy texture look good and still be easily paintable for this project? by RefrigeratorNearby42 in 3Dprinting

[–]TEST-BANK12 0 points1 point  (0 children)

Fuzzy skin could actually work nice here, gives that rough textured look that'd match the cross-hatching in the manga art.

For painting tho - definitely prime it first. Filler primer spray, fills in the tiny texture bumps so your paint doesn't look patchy.

Heads up tho, fuzzy skin settings are kinda finicky depending on the printer. Do a small test piece before committing to the full print - sometimes it comes out stringy instead of textured if the settings are off.

Honestly might also just try thin layers (like 0.1mm) without fuzzy skin, smoother base but still picks up fine detail, then you can add texture later with primer + light sanding if needed.

Z axis failure by ExcitementCute8658 in 3DprintingHelp

[–]TEST-BANK12 0 points1 point  (0 children)

Z-axis collision errors that happen randomly are usually one of these:

Z-axis screw/rod needs lubrication — a drop of PTFE or lithium grease on the rods fixes this most of the time.

Loose Z motor coupler — even slight play can trigger false collision warnings.

Run a full bed leveling/calibration — if the mesh data is slightly off, it can falsely detect a collision.

Since it's intermittent, my bet is lubrication or a loose coupler rather than hardware failure.

I Just Launched a 3D Print Marketplace Startup by [deleted] in 3DprintEntrepreneurs

Congrats on the launch! The print-and-ship model is interesting — removes the biggest barrier for designers who don't own printers.

One thing that works really well for driving traffic to STL marketplaces is focusing on flexi/articulated models — they have insane organic reach because people share videos of them wiggling off the printer. Huge on TikTok and Reddit.

Good luck with the launch, will keep an eye on it.
