Common 3D printing questions
The short answers. Each one links to the full guide.
Why won't my 3D print stick to the bed?
The usual causes are a dirty build plate, a nozzle set too high (Z-offset), a first layer printed too fast, or the wrong bed temperature. Wash the plate with dish soap and warm water, lower the Z-offset until the first layer is slightly squished, slow the first layer to about 20 to 30 mm/s, and match the bed temperature to the filament (about 55 to 65 °C for PLA). All 9 bed-adhesion fixes.
What is the easiest filament for beginners?
PLA. It prints at about 200 to 220 °C on a 55 to 65 °C bed, needs no enclosure, barely warps and is the cheapest common filament. PETG is the usual next step when you need tougher, more heat-resistant parts. Compare them in the filament picker or read the PLA guide.
How do I stop stringing in 3D prints?
Dry the filament first, because moisture is the most overlooked cause. Then lower the nozzle temperature by 5 to 10 °C, make sure retraction is on (short distances on direct-drive extruders, longer on Bowden setups), and raise travel speed so the nozzle spends less time oozing over gaps. Full stringing guide.
What does thermal runaway mean on a 3D printer?
Thermal runaway is a firmware safety shutdown: the printer was heating but the measured temperature did not respond as expected, so it cut power to prevent a fire. Common causes are a thermistor that has slipped out of the heater block, a cooling fan blowing on the block, or a failing heater cartridge. Fix the cause and never disable the protection. How to diagnose it.
How much does it cost to 3D print something?
For most home prints the plastic is the main cost. A 1 kg spool of PLA costs roughly $15 to $25, so a 50 g part uses about $1 of filament. Electricity usually adds only a few cents per hour. Failed prints, nozzles and build plates add a little more. The 3D print cost calculator combines it all into a price per part, and the cost guide shows worked examples.
