Why PETG Warps Differently Than PLA If you’ve made the jump from PLA to PETG, you’ve probably already discovered that PETG has its own personality when it comes to warping. PLA warps because of rapid cooling. PETG warps for partly the same reason — but it’s more stubborn about it, and the solutions that work…
What Is Ringing (Ghosting) in High-Speed 3D Printing? If you’ve recently upgraded to a high-speed 3D printer — or simply cranked up the speed on your trusty machine — you’ve probably noticed something frustrating: wavy, echo-like patterns on the surfaces of your prints, especially around corners and sharp edges. This artifact is called ringing (also…
You check on your print after a few hours and notice something wrong: certain layers are missing entirely, leaving visible gaps or bands in the wall where the printer simply skipped a layer or two. This defect — often called missing layers, skipped layers, or layer gaps — is distinct from under-extrusion because the issue…
Few things are more frustrating than loading a fresh spool of filament, hitting “Print,” and watching your 3D printer push nothing but air. Filament feeding problems are among the most common issues in FDM printing — and while they can stem from a dozen different root causes, most of them are straightforward to diagnose and…
Why Your 3D Printer Endstop Fails — And How to Fix It You hit “Home” on your 3D printer and instead of gently tapping the endstop and backing off, the axis keeps slamming into the frame with a horrible grinding noise. Or maybe it stops randomly in the middle of the bed, nowhere near where…
You’re mid-print and you hear it — a rhythmic clicking or thumping sound coming from your extruder. That’s your stepper motor skipping steps, and every time it does, it fails to push filament into the hotend. The result? Under-extrusion, gaps in your print, or a complete print failure if it happens enough. Extruder motor step-skipping…
You slice a model, start the print, and everything looks fine until you break the part and discover the walls and infill aren’t properly bonded. Or maybe you can see it happening in real-time — visible gaps where the outer walls should meet the internal infill pattern. This is one of those problems that doesn’t…
Your 3D printer’s cooling fan is one of those components you don’t think about — until it stops working. When the part cooling fan fails or underperforms, you’ll see drooping overhangs, messy bridges, stringing, and an overall decline in print quality that can drive you absolutely crazy. The good news? This is one of the…
When Your 3D Printer Screen Goes Dark You power on your 3D printer and nothing happens — the screen stays completely blank. Or maybe it was working fine mid-print and suddenly went dark. A blank or non-responsive display is a surprisingly common issue, and while it looks scary, most causes are fixable without replacing the…
Why Thin Walls Fail in 3D Printing You’ve designed a part with thin walls — maybe a vase, a phone case, or a lightweight enclosure — and your 3D printer just refuses to print them properly. The walls come out incomplete, full of gaps, or don’t print at all. Sound familiar? Thin wall printing is…
