AutoFILL unit

Smarter Resin Management Starts Here

Discover how AutoFILL automatically monitors and maintains the resin level in your printer’s vat, helping prevent dry runs, reduce failed prints and keep long or high-volume jobs running smoothly.

See AutoFILL in action

Designed, Developed and Manufactured by Monocure3D Australia

Resin 3D printing is revolutionising the way parts are manufactured, from prototypes to production. The materials developed by Monocure3D have advanced rapidly in recent years, now offering mechanical properties comparable to ABS plastic and Nylon, while new flexible formulations are pushing this technology to the next level. However, anyone who prints with resin is familiar with the struggles of small vats, forgotten top-ups, mid-print failures, wasting time and money.

AutoFILL™ solves all that. It automatically refills your vat, prevents dry runs, and keeps your prints running safely and smoothly, so you can focus on creating, not topping up.

AutoFILL – Australian made

A World First in Resin Handling Technology

  • Automatic Resin Replenishment – Maintains optimal vat levels without manual intervention.
  • Compatible with all resin-based Printers – Simple tubing setup for universal use.
  • Smart Sensor Technology – Detects resin levels in real-time to prevent overfilling.
  • Low-Noise Operation – Quiet performance for studio, lab, or home environments.
  • Compact & Durable Design – Built to fit seamlessly into your existing setup.
  • No-Touch screen Interface – Easy-to-use controls with adjustable settings.
  • Safe & Reliable – Designed by experienced 3D printing professionals with safety in mind.

Built by Resin. Made for Resin.

AutoFILL has been designed specifically for resin 3D printing. The body, sensor arm, and base are all 3D-printed using our high-performance resin. The parts are optimised to print cleanly without traditional supports, with integrated blade supports in open areas that are easily removed before post-curing.

To support the community, the design files will be available for free download in STL, OBJ, and STEP formats, allowing you to reprint or modify the parts to suit your setup.

AutoFILL will be offered in two versions at launch.

  • Kit version. Includes electronics, pump, hardware and a bottle of AutoFILL resin. You print the parts.
  • Fully assembled version. Supplied complete with pre-printed parts using our specially formulated AutoFILL resin.

How AutoFILL Works

Smart Overflow Prevention

Triple-Level Sensing

Triple-Level Sensing

Three independent sensor pins precisely monitor resin levels. The two primary sensor pins ensure the fill height is maintained, and a third sensor pin reverses the pump.

Time-Based Cutoff

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

Intelligent Pump Logic

Once the primary sensors detect a full vat, the pump stops instantly. Ensuring safe, deliberate operation and preventing unwanted overfill due to sensor error.

What Our Testers Are Saying

“AutoFILL solved a problem I have had for years. I print multiple models on my two Nbee printers, and they are always unattended while printing. Running out of resin mid-print was a waste of my precious time. Now I can start a job and let it run without interruption.”
Orthodontist
New South Wales, Australia
“We tested AutoFILL on multiple MSLA printers, and it maintained a consistent resin height throughout the build. It reduced failures on taller prints and improved repeatability.”
Engineering Workshop
Victoria, Australia
“The installation was straightforward, and the system integrates neatly without major modification. Once calibrated, it just works in the background.”
Industrial Prototyping
Queensland, Australia
“I was sceptical at first, but after running several 10+ hour prints, I would not go back. The consistency in resin level made a noticeable difference.”

Frequently Asked Questions (FAQ)

Find answers to common questions about compatibility, installation, pricing and system operation.

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.
Q: Is AutoFILL™ compatible with my printer?+
A: Yes. AutoFILL is designed as a universal system compatible with most open resin MSLA and DLP printers. It installs externally and integrates with existing vats. Some printer models may require minor adjustments to allow routing of the sensor cable and resin feed tube.
Q: How does AutoFILL™ prevent overflows?+
A: It uses a triple-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.
Q: What are the different modes of Operation?+
A: AutoFILL™ features:
  • AutoFill Mode: Automatically fills the vat as needed.
  • Auto Empty Mode: Automatically empties the vat as needed.
  • Manual Mode: Manual control for on-demand filling.
  • Cycle Mode: Repeated filling at set intervals.
Q: Can I print the parts for it myself?+
A: Yes. The system includes 3D-printable parts to help reduce cost and allow easy replacement. STL files will be provided after purchase.
Q: What size bottles will AutoFILL™ work with?+
A: AutoFILL™ is compatible with any size bottle or container. We will also offer a 20kg UV-safe cube option with an integrated automatic mixing system to keep resin uniform and ready for consistent printing.
Q: When will AutoFILL™ be available?+
A: We’re finalising testing with early adopters. Sign up to be notified when it’s ready for release! Please register to receive updates and be the first to access early-bird specials on Kickstarter.
Q: How much will AutoFILL Cost?+
A:

AutoFILL will be offered in two versions at launch.

The first is a kit version for users who are comfortable assembling the unit and printing the required parts themselves. This option includes all electronic components and hardware, along with a bottle of our latest Tensile+ resin for printing structural parts.

The second option is a fully assembled version, supplied complete and ready to install with all printed components included.

Final pricing will be confirmed at launch, with early supporter pricing available through Kickstarter.
