In this video I will show you how to use the SUNLU filament connector in the most realistic use case scenario with the filament still attached to the roll. I will show you the challenges with using this filament connector tool and how to work around them. Plus, I have a free printable tool to help in the process.
The premise of the SUNLU filament welder is to fuse two ends of filament together to create a seamless joint and join two lengths of filament to become one continuous piece. Before you can get started though, as you've seen in my video a USB power supply is not provided. I would recommend the one I am using in this video. As an Amazon associate I may earn a small commission (at no extra cost to you):
► amzn.to/3WxgWQH
This process can be challenging for a number of reasons and there are a few ways the joint can be compromised. The most common modes of a failed filament fuse are too much heat, too little heat, and pulling the joint apart before it has cooled. I will walk you through my failures and show you a successful filament weld in my trials.
If you're looking for the SUNLU filament connector itself, see the link below:

If you're looking for the SUNLU filament connector alignment tool I designed to help with the process, see the links below:
► makerworld.com/en/models/571704#profileId-491728
Remember to cut the ends of the filament square - not at an angle. Also, apply gentle pressure from both sides during the heating process, don't push too hard. After the filament splicer makes a beeping noise, release the cover and hold the filament steady while you continue to apply gentle pressure while the joint cools. If you need to clean up the splice joint, use a hobby knife to carefully shave the joint into round.
If you're looking for filament, check out SUNLU's filament bundles and vast choices of color. As an Amazon associate I may earn a small commission (at no extra cost to you):
► amzn.to/4csv4AV
Need something tougher? They also have tough PLA+
► amzn.to/4dx57kz
They also have a variety of filament dryers available:
