What a Bowden extruder actually is, mechanically A Bowden extruder is a 3D printer extruder configuration where the stepper motor and gears that push the filament are mounted on the printer’s frame, not on the moving toolhead. The filament is fed through a long PTFE (Teflon) tube — the Bowden tube — that connects the…
Why “fast PETG” is suddenly a category in 2026 Five years ago, PETG was a slow filament. The standard advice was 40-60 mm/s and 230°C, and pushing past those numbers produced stringing, under-extrusion, or gummed-up nozzles. Then in 2024-2025 every major printer manufacturer released machines that cruise at 250-400 mm/s, and PETG users discovered that…
What vase mode actually is, behind the marketing names Slicers each call this feature something different. Cura calls it “Spiralize Outer Contour.” PrusaSlicer calls it “Spiral Vase.” Bambu Studio calls it “Spiral Mode.” All three do the same thing. Vase mode in Cura tells the slicer to print a single continuous outer wall in a…
Why cosplay armor is a different printing problem from cosplay props Cosplay armor and cosplay props look similar from the outside but they are different printing problems. A prop — a sword, a wand, a helmet horn — is a single object printed in one or two pieces, painted, and held in the hand. A…
What FlowFactory actually is, and why it matters in 2026 FlowFactory is the automated flow-rate calibration tool that ships inside Bambu Studio and now appears in third-party slicer forks. The name confuses new users because the older, manual flow-rate calibration procedure is still documented in dozens of older tutorials. The two are not the same….
Why 300mm is the new sweet-spot build volume A 300mm 3d printer sits in a specific slice of the market that did not exist five years ago. Below 220mm you have the hobby-standard Ender 3 and its descendants. Above 500mm you have industrial format printers costing thousands. The 300mm segment — machines with build volumes…
The 2026 landscape of 3D printer monitoring software The phrase 3d printer monitoring software used to mean one thing: OctoPrint running on a Raspberry Pi, watching a print over USB. In 2026 that is no longer true. The category has fragmented into at least five distinct families of software, each with its own philosophy about…
Why TPU fights back when you tune pressure advance Tuning tpu max pressure advance values is the single most frustrating calibration exercise in the hobby. The standard procedure that works beautifully for PLA and PETG — print the classic pressure advance test pattern, look at the corners, pick the cleanest transition — produces numbers that…
Meet the OctoPrint dashboard: your new control panel The first time you log in to a fresh OctoPrint install, the octoprint dashboard can feel either too simple or too cluttered depending on which plugins you imported during setup. Either reaction is normal. The dashboard is deliberately minimalist out of the box and deliberately configurable once…
CoreXY vs bedslinger: the decision, in one paragraph If you are deciding between a core xy vs bedslinger printer in 2026, the short answer is this: bedslingers are cheaper, simpler, easier to repair, and perfectly capable of excellent prints up to roughly 150 mm/s. CoreXY machines cost more, take more tuning, and reward you with…
