Question 2

What printers is this compatible with?

Accepted Answer

Forgely filament works with virtually all open-material FDM 3D printers including Bambu Lab, Prusa, Creality, Voron, and more. No proprietary DRM — print on any machine you like. For printer-specific slicer settings, visit our Print Settings Guide at www.forgely3d.com/print-settings.

Question 3

How long does shipping take?

Orders ship within 48 hours. Standard delivery is 3–5 business days. Orders over $49 ship free. Express options are available at checkout.

Question 4

What's your return policy?

Accepted Answer

We offer a 30-day money-back guarantee. If you're not satisfied with the print quality for any reason, contact us and we'll make it right — no hassle.

Question 5

Do you offer bulk or wholesale pricing?

Accepted Answer

Yes! Wholesale pricing starts at 50+ spools. Approved wholesale accounts save up to $4.24/spool depending on volume tier. Visit our Wholesale page to apply.

Question 6

Why is my PLA stringing?

Accepted Answer

Stringing usually means one of three things: the filament absorbed moisture, retraction is too low for your hotend, or the print temperature is too high. Dry the spool at 45 °C for 4 hours, set retraction to 0.6 mm direct or 4 mm Bowden, and drop nozzle temp 5 °C. If stringing persists with a freshly opened, in-spec spool, it is settings — not material.

Question 7

Why isn't my first layer sticking?

Accepted Answer

In order: bed not level, bed not clean, bed not hot enough. Re-level (preferably auto-calibrate), wipe with isopropyl alcohol, and bring the bed to 60 °C. If you're still fighting first layers, your nozzle is too far off the bed — the filament should look slightly squished, not round.

Question 8

Why are my layers separating?

Accepted Answer

Layer adhesion failures come from low temperature, too much cooling, or a nozzle that is too cold for the speed. Push nozzle temp up 5–10 °C, drop fan to 80% on the first 5 layers, and slow outer walls to 80 mm/s. Forgely PLA holds 50 MPa tensile when printed correctly — separation almost always traces back to under-extrusion.

Question 9

Why does my PLA warp?

Accepted Answer

PLA shouldn't warp much. If it is: bed temp too low, draft hitting the print, or part too tall for the bed adhesion you've got. Set bed to 60 °C, close the printer enclosure or move it out of an air stream, and add a brim for any part taller than 50 mm.

Question 10

Why is my filament brittle or snapping in the spool?

Accepted Answer

Two causes. One: it has been sitting open in humid air for weeks — dry it. Two: it is old or stored hot — PLA hydrolyzes when stored above 30 °C with humidity. Forgely spools are vacuum-sealed with desiccant; brittle out of the bag means it is a manufacturing or shipping issue and we will replace it.

Question 11

Why are there blobs or zits on my outer wall?

Accepted Answer

Pressure advance (or linear advance, depending on firmware) is not tuned. Run a PA test in your slicer — for Forgely PLA at 200 mm/s on a Bambu, start at 0.030. Also check that retraction is not fighting itself: too much retraction on a direct-drive setup grinds filament and causes oozing on the next move.

Question 12

Why is my print under-extruding?

Accepted Answer

Order of likelihood: nozzle partially clogged, extruder tension wrong, filament path obstructed, then — last — wrong filament diameter. Forgely runs at 1.75 mm ±0.02 mm; if your slicer is set to 1.75 mm and you are under-extruding, it is not the filament. Cold-pull the nozzle and check extruder gear for ground filament dust.

Question 13

My print failed and I think it was the spool. What now?

Accepted Answer

Email sales@forgely3d.com with the lot number (printed on the carton), a photo of the print, and your slicer settings. We'll send a replacement and feed the lot back to QC. Our 30-day money-back guarantee covers spools that don't perform.
