Precision Splicing for Limitless Creativity
A Closer Look at the Splicer
Discover the robust clamping mechanism that fuses filaments with pinpoint accuracy, reducing waste and downtime.
Engineered for Durability
From its reinforced casing to the precise alignment system, every detail is crafted for long-lasting performance and effortless splicing.
Your rePET Factory is Nothing Without a Filament Splicer
Turning bottles into filament is only half the process.
When producing rePET filament from bottles, the biggest limitation isn’t the extrusion — it’s the connection.
Short filament segments break your workflow and make reliable printing nearly impossible.
- ✖ Interrupted prints
- ✖ Weak filament joints
- ✖ Inconsistent extrusion
- ✖ Wasted recycled material
This is the hidden bottleneck of every DIY filament setup.
The Endless Splicer fixes this
- ✔ Clean, strong filament joints
- ✔ No PTFE tubes — no cutting, no cleanup
- ✔ Perfect alignment every time
- ✔ Works with recycled & DIY filament
- ✔ Built for continuous production
Endless Splicer vs standard Filament Connectors
A smarter filament splicer for clean joins, no PTFE tubes, and reliable 3D printing workflows.
Endless Splicer
- ✔ Clean filament welding with no excess material
- ✔ No PTFE tubes – no cutting or post-processing needed
- ✔ Simple “toaster-style” workflow – insert, close, done
- ✔ Perfect alignment for strong and consistent filament joints
- ✔ Works with nearly every 1.75 mm filament
- ✔ Reliable results for continuous 3D printing
Standard Splicers (e.g. Sunlu FC01)
- ✖ Requires PTFE tubes for joining filament
- ✖ Extra cutting and cleanup after welding
- ✖ Excess material can affect print quality
- ✖ Less consistent filament alignment
- ✖ More steps and handling required
- ✖ Less efficient workflow for frequent use
