The Future of Resin 3D Printing Starts Here!

Introducing AutoFILL™
Filling is just the beginning…
AutoFILL™ | Designed for Everyone and Every Printer
Resin 3D printing is at the forefront of additive manufacturing, delivering parts that look and feel like they’ve come straight from the factory floor. This 3D printing technology is rapidly moving beyond prototyping into real-world production. From engineering workshops to dental labs, where accuracy, consistency, and repeatability are essential.
Whether you’re printing dental models in a lab, running a print service, producing short-run parts, or managing a classroom where students are learning to print, AutoFILL™ solves the problems we’ve all faced:
- Most resin vats aren’t large enough for long or high-volume prints.
- Manual top-ups are easy to miss and often forgotten.
- Running out mid-print means total failure, wasted resin, and lost time.
- There’s no “resume” option; if a resin print stops, you start from scratch.
- Built-in fillers often fail, risking dry runs or overflows that can damage your printer.
- In professional settings, limiting resin contact is crucial; safety always comes first.
With AutoFILL™, you get a safer, smarter, and more reliable workflow, whether training the next generation of makers or running a high-throughput production setup.

The Smart Way to Print
Fully automated resin top-ups
AutoFILL™ monitors your vat and adds resin when needed, eliminating the need for manual refills.
Enjoy uninterrupted printing, even on long or high-volume jobs.
Prevents mid-print failures
Never lose a print due to an empty vat again.
AutoFILL ensures consistent resin flow from start to finish.
Works with any MSLA/DLP printer
Designed for universal compatibility across most resin printers.
No special adapters or proprietary systems required.
Whisper-Quiet Operation
The precision peristaltic pump runs silently in the background.
Easily swap hoses when a colour change is required.
Smart Overflow Prevention
Peace of mind, built in.

Triple-Level Sensing
Three independent sensor pins precisely monitor resin levels.
-
The two primary sensor pins ensure the optimal fill height is maintained.
-
A third emergency sensor pin acts as a safety backup, reversing the pump if levels rise too high.

Time-Based Cutoff
The system tracks fill duration and stops the pump if it exceeds the safe time limit, providing an added safeguard in case sensors ever lose contact or resin flow is restricted.

Intelligent Pump Logic
Once the primary sensor detects a full vat, the pump stops instantly. It won’t restart until manually reset — ensuring safe, deliberate operation and preventing unwanted overfill due to sensor error.

Regular Sensor Checks
Before every fill cycle, the system performs a diagnostic scan of all sensors. If any sensor fails the check, AutoFILL won’t initiate the process, keeping your printer safe.

Software Safeguards
Smart software constantly checks for logical inconsistencies — like a sensor triggering while the pump is off — to detect faults before they become problems.
Set and Forget with 20kg Resin Support
We wanted a system that could feed resin continuously from 20kg UV-safe containers, keeping the workflow clean and uninterrupted. But we also knew no one was shaking a 20kg resin cube.
We built a simple, open-source mixing system using 3D-printed parts and a small gear motor. It automatically mixes the resin a few times a day, or can be set to manual mode for a more aggressive stir. This is ideal if the resin has been sitting for a while. The resin is drawn from the bottom of the drum via a custom-designed 3D-printed intake, which ensures a consistent flow of well-mixed material.
Intuitive Non-Touchscreen Menu
Powerful control made simple.
AutoFILL™ is built with an easy-to-navigate touchscreen interface, so you’re always in control — no app, no PC, no hassle.

RUN MENU
Quick-access to core operations:
- Auto FILL – Maintain optimal vat levels automatically

Built by Resin. Made for Resin.
AutoFILL™ has been engineered with resin 3D printing in mind. The main body, sensor arm, and foot are all 3D printed using our high-performance resin. Designed specifically for resin printers, the components print cleanly with no supports required. Strategic blade supports are used in open areas, such as the LCD screen cutout, and can be easily removed before post-curing.

- Kit Only (unbuilt) – Includes all electronics, pump, hardware and AutoFILL™ Resin (you print the parts)
- Finished Product – Fully built AutoFILL™, includes pre-printed parts using our specially formulated AutoFILL™ resin
A bottle of this custom-labelled resin will also be available for those who want to print the parts themselves with guaranteed compatibility and performance.
FAQ (Frequently Asked Questions)
Q: What is the AutoFILL™ system?
A: AutoFILL™ is an innovative resin pump system that automatically maintains optimal resin levels in your 3D printer vat. Developed by resin printing experts, it works with virtually any 3D printer and includes advanced safety and mixing features.
A: Yes. AutoFILL™ is a universal system that works with most MSLA and DLP printers. It connects externally and doesn’t require any modification to your printer.
A: It uses a dual-level sensor system. One sensor maintains the correct fill level, while a secondary sensor acts as an emergency shutoff if levels rise unexpectedly. Software checks and timed cutoffs provide additional layers of safety.
A: AutoFILL™ features:
-
Auto Mode: Automatically fills the vat as needed.
-
