失敗の壁
If you're not failing, you're not pushing your printer hard enough. Every disaster here made the next print better.
Articulated dragon detached from the bed at layer 47. Nozzle kept going for 6 hours, producing the most expensive bird nest in history. Came back to find a filament tumbleweed sitting on the plate.
Glue stick on textured PEI for tall narrow prints. Also: enable first-layer inspection on the Bambu.
Printed an ABS Benchy without an enclosure "just to see." Corner lifted at layer 3, hull warped into a banana shape. The chimney was somehow perfect.
ABS needs an enclosure. There are no shortcuts. Stop testing this theory.
Overfilled the resin vat on the Saturn. Print started, suction pulled the FEP sheet, resin leaked onto the screen protector. Spent two hours cleaning cured resin off the underside with IPA and a plastic razor.
Fill to the MIN line, not the MAX. The MAX line is a lie for small prints.
Three prints in a row came out with a 5mm horizontal shift at the same height. Blamed the slicer, the gcode, the firmware. Turned out a belt tensioner screw was loose.
When the same failure repeats at the same height, it is hardware. Check belts and eccentric nuts.
Carbon-fibre PETG partially clogged the brass nozzle 18 hours into a structural bracket. Print continued with under-extrusion, producing a part that looked normal but crumbled under finger pressure.
Hardened steel nozzle for any abrasive filament. Period. Also set up clog detection in firmware.
Spent 40 minutes carefully removing tree supports from a detailed miniature. On the final support, the sword arm snapped clean off. Superglue left a visible seam.
Print minis at 0.08mm with paint-on supports only. Tree supports are for functional parts, not details.
Four-colour print. Slot 3 tangled inside the AMS at hour 2. Machine kept trying to pull, grinding the filament until it snapped. The other three colours printed perfectly around the gaps, creating an accidental modern art piece.
Unspool and re-wind any filament that has been sitting in the AMS for more than a week. Moisture makes it brittle and tangle-prone.
Sliced a samurai figurine at 1000% instead of 100%. Printer started the first layer and the skirt alone used half the bed. Cancelled it but not before wasting 45 minutes of heat-up and purge.
Always preview the gcode before sending. Bambu Studio shows the estimated size — read it.
The worse it is, the better the lesson. Send your failures and I'll add them (with credit).
