The main differences between J1 and J1s are as follows
1. The J1s is equipped with the additional Print Cooling Fan. You won't need to remove the top panel to print PLA.
2. In the package of J1s, we replaced the white PLA with Breakaway Support for PLA so that you can try support printing right away.
3. We also pre-installed the doors and side panels for you, making it even easier to start right off.
4. If you plan to buy a J1 model and have the need for extra print cooling, you can choose either a J1 plus an Upgrade Kit or a J1s.
