説明
Filament is the one consumable that decides whether a print succeeds before the first layer is laid. A spool that has absorbed an afternoon of humidity will pop, string and delaminate, and no amount of slicer tuning recovers it. This five-roll PETG set is vacuum-sealed at 1.1 kg net per roll, 1.75 mm with a tolerance held to plus or minus 0.02 mm, which is the number that matters when a direct-drive extruder is pushing eighty centimetres of material a second.
PETG occupies the useful middle ground that PLA and ABS each fail to cover. It takes the layer adhesion and chemical resistance that ABS offers without the warping and the enclosure requirement, and it holds impact and heat far better than PLA. Elongation at break is rated at 210 percent, so brackets flex instead of snapping. Print temperature sits at 220 to 230 degrees Celsius with a bed at 60 to 80 degrees, and the melt index of 6 to 11 g per 10 minutes keeps flow stable across long jobs rather than drifting as the spool heats up.
Five rolls of mixed colour in one box is deliberate. It removes the single-colour purchase loop that has a workshop ordering one spool at a time and paying shipping on each, and it gives a designer enough material to prototype a shape in one colour and print the final part in another without a second order. Every roll is dried and bagged, RoHS and REACH compliant, with a one-year shelf life if the bag stays sealed.
The spool is not packaging. It is the material, and it deserves to be specified like one.
What Makes It Different
- ✦Five vacuum-sealed 1.1 kg rolls of PETG in mixed colours, one box per project
- ✦1.75 mm diameter held to plus or minus 0.02 mm for consistent extrusion pressure
- ✦Zero-bubble, dried and bagged at packing, so no popping or steam pockets mid-print
- ✦Layer adhesion that resists delamination on functional parts and enclosures
- ✦Elongation at break of 210 percent, which means brackets flex rather than crack
- ✦Stable melt index of 6 to 11 g/10 min through a full spool
- ✦RoHS and REACH compliant, with a one-year shelf life while sealed

Where It Earns Its Place
Print farms run PETG for jigs, fixtures and end-use parts that have to survive a workshop floor, and buy in five-roll sets because changeovers cost machine time. Product designers use the mixed colours to separate prototype iterations by revision without re-slicing. Hobbyists who have been buying single spools will find the set cheaper per roll and better sealed than the loose stock on a shop shelf. Anyone printing outdoor brackets, camera mounts, cable guides or replacement knobs is squarely in PETG territory rather than PLA.

Questions Buyers Actually Ask
Q: What temperature should I actually print this at?
Start at 230 degrees Celsius with a 70 degree bed. If you see stringing, drop the nozzle 5 degrees; if layer adhesion feels weak on a functional part, raise the bed and slow the outer wall rather than pushing temperature higher.
Q: Does PETG need an enclosure?
No. That is one of its advantages over ABS. A draught-free room is enough for most parts; large flat prints benefit from a brim more than from an enclosure.
Q: Is 1.1 kg the same as the 1 kg spools I usually buy?
It is slightly more material per roll, and the gross weight of 1.35 kg includes the spool. Check that your spool holder clears the hub before ordering five at once.
Q: Will it fit a standard spool holder?
Yes, it uses the common 1 kg-class hub. The five-roll box is heavier than a single spool, so lift it out rather than dragging it onto the holder.
Q: How should I store the rolls I am not using?
Keep them sealed with the desiccant until needed. Once a roll is open, a dry box or a sealed bag with desiccant will hold it for months in a humid workshop.
Q: Can I dry a roll that has absorbed moisture?
Yes. A dedicated filament dryer at 60 to 65 degrees Celsius for four to six hours recovers most PETG. Oven drying works but is far less even and easier to overheat.
Q: Does it work for food-contact or outdoor parts?
PETG handles outdoor UV and moisture better than PLA, so garden and automotive brackets are reasonable. It is not certified food-contact, so avoid direct food surfaces.
Q: Are all five rolls the same colour?
The set is mixed colours. If a specific colourway matters for a production run, note it at checkout and the pack is picked accordingly.
