Quick Summary
SUNLU Rapid PETG Filament is a 2KG 3D printer filament pack in black, supplied as 2 x 1kg on reusable spools. It is 1.75mm filament with a stated dimensional accuracy of ±0.02mm, and the product is presented for high-speed printing from 30 to 600mm/s.
The pack also notes vacuum packing with desiccant, a satin matte surface, and recommended temperature settings that change with print speed. Check your printer’s filament size and the selected colour before ordering.
Who It Is Best For
This filament suits buyers looking for 1.75mm PETG filament in a twin 1kg format, especially where high-speed printing, stated accuracy and reusable spools matter. It is also relevant if you want a black filament pack with the same colour supplied in both spools.

Why Buyers Choose It
- The stated 1.75mm size makes it easy to check compatibility with the printer before ordering.
- Two 1kg spools give a clear split of the 2KG total, which helps with planning longer prints or colour use.
- The ±0.02mm accuracy claim gives a specific diameter tolerance for buyers comparing filament consistency.
- The satin matte surface is a useful detail if you want a different finish from ordinary glossy filament.
How It Works
The product is supplied as filament for 3D printers and includes recommended bed and print temperature settings. The stated guidance is 70 to 80℃ bed temperature, with print temperature ranges of 230 to 240℃ at 50 to 100mm/s, 240 to 255℃ at 100 to 300mm/s, and 255 to 270℃ at 300 to 600mm/s.
The guidance also says temperature should be adjusted according to print speed changes. Use those settings as a starting point and match them to your printer’s requirements.
Real World Use
For day-to-day use, this pack gives you two black spools rather than one larger single spool. That can be useful if you want to separate jobs, keep one spool as backup, or handle the filament more easily during storage.
The vacuum-packed, desiccant-protected packaging is aimed at keeping the filament dry before use, and the reusable spools are a practical detail for users who want to keep or reuse the spool after the filament is finished.
What To Know Before You Buy
Check that your printer uses 1.75mm filament before choosing this pack. The listing is for black filament on both spools, so it suits buyers who want that exact colour combination. The printed result is described as satin matte, and the recommended temperature range varies with print speed, so match your settings carefully.
Pros: The pack combines a stated 2KG total with two reusable 1kg spools and a tight ±0.02mm diameter tolerance.
Cons: The temperature guidance changes with print speed, so you need to match your settings to your print plan.
