Introducing The Slunaz FF1R filament joiner
An ideal solution for seamlessly combining a selection of filament materials. While it excels with PLA, ABS, PETG, and PET-B (commonly referred to as PET1; derived from DIY home Pultrusion methods, enabling the creation of customized 3D filament from plastic bottles), its customizable settings should extend beyond these recommendations.
The filament tolerance ranges from 1.75 to 1.76mm, accommodating most standard filament diameters. It's advisable to opt for a filament with tighter tolerances. Understanding the characteristics of your filament brand is imperative. This advice also applies to home-made PET1 filament, where maintaining a diameter below 1.75mm is essential to prevent any unit binding.
This tighter tolerance is critical but also has its advantages. It ensures a consistent join that is uniform to the accuracy tolerance of your 3D printer's hotend. Resulting in an ultra smooth uniform join that doesn't require any extra cleaning or attention beyond what's beautifully produced by the unit itself.
Alternative units with comparable results come at a higher price and do not offer the same level of customization as the Slunaz FF1R.
The Slunaz FF1R empowers you with the following capabilities:
Exact control over melt temperatures and cooling duration.
Varying spooling speeds to match your specific requirements.
Streamlined automation for continuous filament joining, needing no additional user intervention beyond loading the next filament to effortlessly create your newly reformed spool.
In the context of PET1 Pultrusion methods, typically a 2-Liter bottle yields approximately 25 grams of filament, equivalent to about one hour of printing time.
Most users prefer to combine these smaller quantities into larger spools; such as a 1-Kilogram spool, allowing for extended 3D printing sessions. Whether it's for an 8-hour workday, a full 8-hour night's sleep, or both. The hassle of continuously refilling the printer every hour is not desirable.
The Slunaz FF1R offers a comprehensive solution to address this issue!
The Slunaz FF1R is particularly well-suited for making the most of leftover scraps; which are commonly generated by standard Bowden 3D printers and other multi-material methods, often leaving behind 5-10 inches of unused filament strands.
If you find yourself regularly generating these leftovers, the Slunaz FF1R offers an excellent solution to recovering and repurposing this filament. This presents an effective means of minimizing waste and enabling you to reuse it for future prints.
Coming from Europe; The SLUNAZ by Stefano Lunazzi, is currently running a now FULLY FUNDED Kickstarter campaign and plans to start shipping in February 2024.
From today you can also pre-order FF1r from United States, Switzerland, Canada and UK! Shipping costs are: USA: 30 euros (approximately) and Canada 50 euros + customs duties (charged to you) of 3.1% UK: 15 euros Switzerland: 50 euros
The SLUNAZ FF1R is offered as a DIY small parts kit, which not only saves on shipping costs but also allows customers to 3D print the components themselves. This way, they can give their Slunaz FF1R a personal touch to match their style and other 3D printer accessories.
