Refill Packaging


Many of our customers complained about how to deal with their empty spools and asked if we could recycle them. This is a common issue for most of the 3D printing enthusiasts and to recycle the empty spools seems not feasible because of the transportation costs and the possibility to resale them. The piling up of spools not only is a waste of resources but also cause environmental pollution problems.

To solve this issue, we decided to develop the technology of refill packaging with the idea that users can refill their empty spool when they used up the filament. We spent a lot of effort in developing this technology since it is very tricky to wind filament without spools. However, we think it is worthy because of the huge benefits both for consumers and the environment.


1. Protect the environment; reduce usage and littering of plastic materials.
2. Reduce spool costs for consumers and increase resalers' competitive advantages.
3. Save packaging volume that also reduces transportation and storage costs.
4. Reduce the possibilities of filament fracture and breakage. 
This is our new finding in our R&D lab. When we wind filament on a normal spool, the process causes a lot of stress on the filament during fast pulling and winding. There is no way for the stress to release before using the filament. Therefore, the continuing pressure inside the filament makes the PLA filament fracture issues even worse. With our refill packaging technology, the filament roll was removed from the reel of winding machine and the stress was released at the same time. In our observation, the stress relief will largely reduce the fracture problems.
