A step-by-step guide to adding modifier geometry in CURA, so you can change wall count, top and bottom layers only where a part actually needs it.

Printing face shields for local hospitals, I worked through what actually cuts the time: layer height, extrusion width and perimeters, without losing strength.

I soaked printed samples from a dozen materials in 70% IPA for 48 hours.

I built the Precious Plastic shredder from a laser-cut kit, then added a printed hand crank and stackable sieves to get a consistent particle size for extrusion.

You can measure your hotend's flow limit with nothing but a scale.

A couple of months ago Colorfabb released two really interesting new Filaments that are called VarioShore TPU and LW or Lightweight PLA.

Zits and blobs often come from too many tiny G-code segments.

Even though you can nowadays get almost any thermoplastic as a 3D printing filament PLA, PETG and ABS are still the most common ones used.

My script varies extrusion so infill gets denser toward the walls.

Almost a year ago I released a very popular video on threaded inserts for 3D prints on which I got a ton of suggestions and comments.

I’m sure you’ve all heard or even experienced it already that using a larger nozzle in you 3D printer seems to result in quite a bit more sturdy parts.

The Sapphire Pro is a project, not a tool.

Nobody touches extrusion width, but it matters.

Thinner layers look better, but are they stronger?

In the past I never really worried much about nozzle wear because I rarely printed abrasive materials and when I did, I switched my nozzle for a hardened steel one.

Annealing PLA got me 7.5% more tensile strength and 16% on lying hooks.
