Filamento de impresora 3D

Answer: It means there’s a minimum order quantity of 6kg for that deal—typically 6 rolls of 1kg filament—often tied to a bulk discount format.

Answer: Yes—several products are explicitly labeled “Mix & Match Over 6 Rolls Bulk Order”, which indicates you can combine multiple variants within the bulk minimum rather than buying all the same spool.

Answer: Yes—SUNLU lists PLA 1KG and PLA+ (PLA Plus) 1KG bulk options on the collection page, both shown with bulk “over 6 rolls” style listings.

Answer: Match filament to your use case:
PLA: easy prints, decor, prototypes
PETG: tougher, more temperature/impact resistant, good for functional parts
TPU: flexible parts like bumpers, phone cases
ABS/ASA: higher heat resistance; ASA is better outdoors (UV)
Then confirm your printer can reach the needed nozzle/bed temps (and whether you have an enclosure).

Answer: It depends on material and brand, but common starting ranges are:
PLA: ~190–220°C nozzle, ~0–60°C bed
PETG: ~220–250°C nozzle, ~70–90°C bed
TPU: ~210–240°C nozzle, ~30–60°C bed
ABS/ASA: ~230–260°C nozzle, ~90–110°C bed (often needs enclosure)
Always adjust based on your printer, speed, and print behavior.

Think of PLA as the "aesthetic" material (easy to print, great colors, brittle) and PETG as the "functional" material (stronger, more heat-resistant, slightly flexible). PETG is better for items that will be outside or used in mechanical assemblies, though it is prone to "stringing."

Listen for a "crackling" or "popping" sound at the nozzle during a print. Visually, you'll see tiny bubbles in the extruded plastic or an unusually rough surface finish.
