Why Retraction Settings Matter on the Ender 3 V2 Retraction is the single most important setting for eliminating stringing and oozing on any FDM printer. When your printhead travels between two points without extruding, the filament in the melt zone remains molten and tends to ooze out — gravity and residual pressure push it through…
Why Bed Temperature Matters The heated bed on your 3D printer serves one primary purpose: keeping the bottom layers of your print warm enough that they don’t contract and peel away from the build surface. Different filament materials have different glass transition temperatures, melting points, and shrinkage rates, which means each one needs a different…
Why ABS Warps So Much Let’s start with the root cause, because understanding the problem is half the battle. ABS (Acrylonitrile Butadiene Styrene) has a significantly higher coefficient of thermal expansion than PLA or PETG. When ABS cools from its extrusion temperature (~240°C) to room temperature, it shrinks by approximately 0.7–0.8%. That might sound small,…
What Are Brims and Rafts? Before we get into when to use each one, let’s make sure we’re on the same page about what these features actually do. I’m Mike Reynolds, and I’ve been 3D printing for over six years now. In that time, I’ve probably used brims and rafts on thousands of prints, and…
Why Do 3D Print Corners Lift and Curl? If you’ve spent any time with a 3D printer, you’ve probably watched in frustration as the corners of your print slowly peel upward from the bed. This phenomenon — commonly called warping or corner lifting — is one of the most common problems in FDM printing, and…
The Ender 3 V2 is one of the best-selling 3D printers ever made, and for good reason — it’s affordable, capable, and has a massive community behind it. But out of the box, its default Cura retraction settings aren’t optimized. The result? Stringing, blobs, and messy prints that don’t match the beautiful examples you see…
Your heated bed temperature might be the single most important setting you’re not paying enough attention to. Set it too low and your prints won’t stick. Set it too high and you’ll get elephant’s foot, difficult removal, or even material degradation. Every filament has a sweet spot, and finding it makes the difference between fighting…
ABS is one of the most versatile 3D printing materials available. It’s strong, heat-resistant, and can be vapor-smoothed with acetone for a glossy finish. But printing ABS has a reputation for being difficult, and that reputation is largely earned — unless you have an enclosure. An enclosure transforms ABS from a frustrating material into a…
Every 3D printing beginner eventually faces this question: should I use a brim, a raft, or a skirt? These build plate adhesion helpers serve different purposes, and choosing the wrong one can waste filament, add cleanup time, or fail to solve your adhesion problems altogether. After years of printing, I’ve developed a clear framework for…
You’ve probably experienced this: halfway through a print, the corners start lifting off the build plate, curling upward like a dried leaf. This warping effect is one of the most frustrating problems in 3D printing, and it can ruin hours of work in seconds. The good news? It’s almost always preventable once you understand what…
