ABS / ASA

ABS and ASA Bridging and Overhangs

ABS and ASA must bridge with 80% overhang fan against a 10-60% body limit — a real conflict…

ABS / ASA

Getting a Perfect First Layer with ABS and ASA

ABS and ASA first layers live or die on heat soak: 90-100 °C beds given time to saturate, zero fan, brims…

PETG

Getting a Perfect First Layer with PETG

Bridging

How to Fix Bad Bridging

Sagging bridges: 20 mm/s bridge speed, overhang fan for engineering materials, reorientation.

Adhesion

How to Fix Bed Adhesion Problems

Prints that won't stick or pop off mid-print: plate washing, plate/material matching, bed temperatures.

Elephant foot

How to Fix Elephant Foot

Bulging bottom edges: compensation values, first-layer bed temperature and the CAD chamfer fix.

First layer

How to Fix First Layer Problems

Patchy or gappy first layers: plate prep, calibration, first-layer speed and temperatures.

Ghosting

How to Fix Ghosting and Ringing

Ripple echoes after sharp corners: vibration calibration, outer-wall speed, belt tension and frame stiffness.

Delamination

How to Fix Layer Separation

Cracks between layers: hotter nozzle, less fan, chamber heat — and when an open printer can't be saved.

Clogs

How to Fix Nozzle Clogs

Blocked nozzle or clicking extruder: cold pulls plus the five causes that make clogs come back.

Extrusion

How to Fix Over-Extrusion

Blobs, zits and bulging corners: flow ratio, filament diameter and the built-in calibration.

PETG

How to Fix PETG Elephant Foot

PETG's hot 70-80 °C bed keeps its base soft, so bottom edges bulge. Compensation values, bed-temperature trims and the chamfer trick, tuned for PETG.

PETG

How to Fix PETG Layer Adhesion Problems

PETG normally welds layers beautifully — when it doesn't, it's moisture or an over-aggressive fan…

PETG

How to Fix PETG Over-Extrusion

PETG's stock flow ratio is 0.95 for a reason. Why a PLA-cloned profile over-extrudes PETG by design…

PETG

How to Fix PETG Stringing

PETG is the stringiest of the common filaments. Fix it in the right order: dry the spool, come down from the hot end of PETG's range…

PETG

How to Fix PETG Under-Extrusion

Thin walls and gaps in PETG prints usually mean the print outruns PETG's 16 mm³/s melt limit — or the spool is wet…

PETG

How to Fix PETG Warping

PETG rarely warps — when it does, the bed is too cold, the fan too aggressive, or the plate greasy…

PLA

How to Fix PLA Over-Extrusion

Blobby corners, ridged top surfaces and fat dimensions in PLA come down to flow ratio and diameter…

PLA

How to Fix PLA Stringing

PLA should print almost string-free. If yours doesn't, the spool is old or damp, the nozzle is too hot…

PLA

How to Fix PLA Under-Extrusion

PLA under-extrusion on a modern printer points to heat creep, a partial clog or a volumetric limit set above what the hotend can melt…

PLA

How to Fix PLA Warping

PLA is the least warp-prone filament, so PLA warping points to something specific: a greasy plate, a draft, an aggressive side fan…

Stringing

How to Fix Stringing

ABS / ASA

How to Fix Stringing with ABS and ASA

ABS and ASA string when printed at the top of their 240-280 °C window or after absorbing moisture…

TPU

How to Fix TPU Stringing

TPU under-extrudes when anything stretches it before the extruder: spool drag, AMS feed paths, too much speed…

Top surface

How to Fix Ugly Top Surfaces

Pillowing and pinholes on top: top shell layers, infill density and ironing.

Extrusion

How to Fix Under-Extrusion

Gaps and thin walls: max volumetric speed, temperature, generic-filament tuning and clog checks.

Warping

How to Fix Warping

Corners lifting off the plate? Plate temps per material, brim, the auxiliary-fan trick and chamber heat.

PETG

How to Fix a Rough PETG Surface

PETG should print glossy. Pits, fuzz and bubbles mean moisture; dull ripples mean speed or flow…

Surface quality

How to Fix a Rough Print Surface

Grainy, bubbly or rippled walls: moisture first, then outer-wall speed and flow calibration.

ABS / ASA

How to Get ABS and ASA to Stick to the Bed

ABS and ASA adhesion is a heat problem: 90-100 °C beds, zero early cooling, warm chamber air, and glue as insurance…

PETG

How to Get PETG to Stick to the Bed

PETG adhesion is all-or-nothing: it welds to hot clean PEI and slides off cold or greasy plates…

PLA

How to Get PLA to Stick to the Bed

PLA should stick to a clean PEI plate with zero help. If it doesn't: soap wash, 55-65 °C bed, slower first layer…

TPU

How to Get TPU to Stick (and Come Off Again)

TPU's adhesion problem is usually too much grip, not too little…

PETG

PETG Bridging and Overhangs: What to Expect

PLA Clogs in Enclosed Printers: Heat Creep Explained

PLA that jams 30-60 minutes into a print on an enclosed printer is heat creep: PLA softens at ~45 °C…

TPU

Why TPU Jams the Extruder (and How to Stop It)

TPU doesn't clog nozzles — it buckles in the extruder. The feed-path rules…

TPU + AMS

How to Print TPU Through the AMS
