Symptoms of Uneven Bed Heating Your first layer looks perfect in the center of the bed but keeps peeling up at the edges. Or you’ve dialed in your Z offset perfectly at one corner, but the opposite corner either scratches the bed or doesn’t stick at all. Before you blame your leveling, check your bed…
What Is Metal-Filled Filament? Metal-filled filament is exactly what it sounds like: a standard thermoplastic base (usually PLA) mixed with fine metal powder. The result is a filament that prints on any FDM 3D printer but produces parts with a distinctly metallic look, feel, and weight. When post-processed with sanding and polishing, metal-filled prints can…
Why ABS Still Matters in 2026 ABS gets a bad reputation in the 3D printing community. It smells when you print it. It warps if you look at it wrong. It demands an enclosure, a heated bed, and more patience than most beginners have. So why does anyone still use it? Because when you need…
What Sagging Overhangs Look Like (And Why They Happen) You’ve sliced a model with a beautiful 45-degree overhang, hit print, and come back to find the underside looks like melted cheese hanging off a pizza. The layers droop, curl, and leave behind a rough, ugly surface that no amount of post-processing can fully fix. Welcome…
Why Your Stock Cooling Fan Duct Probably Isn’t Good Enough If you’ve been printing for more than a few weeks, you’ve probably noticed that some prints come out looking great while others have ugly drooping overhangs, rough surfaces, or curling corners. In many cases, the culprit isn’t your slicer settings or your filament — it’s…
The Bowden Tube Gap Problem Explained If your 3D printer has started under-extruding, producing inconsistent lines, clicking at the extruder, or leaving tiny blobs on the surface for no apparent reason — there’s a good chance you have a gap between your Bowden tube and the nozzle inside the hotend. This is one of the…
Speed Printing Has Changed Everything Three years ago, printing at 150 mm/s was considered fast. Today, Bambu Lab printers routinely hit 500 mm/s, Creality’s K1 series cruises at 600 mm/s, and machines like the Voron Trident can sustain 300+ mm/s with stunning quality. The high-speed 3D printing revolution isn’t coming — it’s already here, and…
Why Brims and Mouse Ears Exist Warping is the oldest enemy in 3D printing. Your beautifully designed part starts peeling off the bed mid-print, corners curl upward like dried leaves, and you come back to find a bird’s nest of spaghetti instead of a finished part. The root cause is differential cooling — the bottom…
What Is Bed Tramming and Why Does It Matter? Here’s a dirty secret about 3D printing: “bed leveling” is a misnomer. What you’re actually doing is tramming — adjusting the build plate so it sits perfectly parallel to the printer’s motion system. The bed doesn’t need to be level relative to the earth (your printer…
Why Post-Curing Matters for Resin 3D Prints If you’ve ever pulled a resin 3D print off the build plate and thought it was done, you’re not alone — but you’re also not finished. Fresh resin prints are only partially polymerized, which means they’re softer, weaker, and more prone to warping than they should be. Post-curing…
