I'm new to desktop 3D printing and trying to figure out a solid workflow from model preparation to post‑processing. What slicing settings do you usually start with for PLA, and how do you handle support structures without over‑complicating the print? Any tips on calibrating the bed and maintaining consistent extrusion? Also, I'm curious about the best way to organize and store printed parts to avoid warping. Would love to hear your go‑to methods, common pitfalls to avoid, and resources for learning the basics. Thanks!

For PLA I usually start with a 0.2 mm layer height, 50–60 °C nozzle and a 60 °C heated bed. In Cura a 50 mm/s print speed with a 0.4 mm nozzle works well for most hobby‑grade parts, and I set retraction to about 6 mm at 40 mm/s to keep stringing in check. Infill can be as low as 15–20 % for visual models, but I bump it up to 100 % when I need strength (e.g., functional brackets). If you compare this to a PETG workflow, you’ll notice PETG needs a higher nozzle temperature (≈230 °C) and a slower cooling fan, which often means longer prints and a higher chance of oozing—so PLA stays the more forgiving choice for beginners.
When it comes to supports I prefer the “tree” style in PrusaSlicer (or “support interface” in Cura) because it adds material only where it’s needed and leaves a clean removal surface. Keep the overhang angle limit around 45°, and set the support density to 10–15 % for most geometry; that way you avoid the dense “cage” that can make post‑processing a nightmare. By contrast, resin printers generate supports automatically on any overhang, which eliminates the need for tweaking support settings but introduces the hassle of cleaning cured resin and dealing with a more fragile build platform.
Bed leveling is the foundation of a reliable workflow: run a three‑point paper test, then enable mesh bed leveling (or BLTouch if you have one) and fine‑tune the Z‑offset until the first layer is a uniform “slightly squished” line. For extrusion consistency, run an E‑step calibration (measure a 100 mm filament extrusion and adjust the steps/mm accordingly) and then do a simple flow‑rate test—print a single‑wall cube and measure the wall thickness. Finally, store printed PLA in airtight containers with desiccant packs; humidity is the main cause of post‑print warping and brittleness. A simple part rack with vertical slots keeps prints upright and reduces stress on the layers, which is a lot less hassle than trying to “re‑flatten” warped parts later.
