Resiners G3 Resin Curing Station
The G3 resin curing station from Resiners combines a circulating hot-air system with a dual-wavelength UV light to deliver a one-stop curing solution for both epoxy and UV resins. Epoxy resin tends to take about two hours, while UV resin can cure in roughly one minute, enabling rapid iteration for time-sensitive projects, workshops, or small-batch production. A reversible PC base provides high-temperature and deformation resistance for stable operation during longer sessions. The platform integrates a 3D thermal cycle with a cooling system and temperatures controlled in a safe, consistent range.
Operation is guided by a touchscreen featuring three working modes: Flat Mold, Tall Mold, and UV Light. Each mode includes a default curing program, so beginners can select a program with a single touch. Temperature and time settings are adjustable for advanced users who need precise control of curing quality. The unit supports a custom dual-wavelength UV light (365 nm and 395 nm) to ensure thorough curing across resin types, reducing issues such as warping, bubbles, and sinking. The G3 is designed for versatility, making it suitable for jewelry, decorative pieces, or tiny epoxy molds in professional studios.
Resiners Larger Tray Curing Station
This model emphasizes speed and capacity with a focus on a larger curing tray. It delivers a two-hour cure time, and a controlled environment ensures consistent results across batches. Winter preheating helps reduce resin viscosity on cold days, facilitating easier pouring and stirring and minimizing bubble formation. The “Auto Curing” feature simplifies operation—press the power button and the unit automatically adjusts temperature to complete curing in about two hours. The design is optimized for larger or multiple molds, enabling efficient throughput for hobbyists who handle several pieces at once.
The auto-curing workflow reduces guesswork, while the larger tray accommodates more parts per cycle. The device is well-suited for projects that require steady, repeatable curing without manual timing. Its user-friendly approach makes it a practical option for makers who want reliable results with less hands-on management, especially when processing small to medium batches of epoxy resin molds or decorative pieces.
ELEGOO Mercury Plus 3.0 Wash and Cure
The ELEGOO Mercury Plus 3.0 is a larger wash-and-cure station designed for LCD/SLA/DLP 3D-printed models. It improves post-processing by offering a significantly larger wash volume (up to 7.5L) and a curing area of up to approximately 250 mm in diameter and 290 mm tall. The system employs a 360° UV light setup with 24 LEDs and a reflective mirror design to project even illumination, delivering uniform curing across complex geometries. A rotating turntable helps achieve consistent exposure on all sides, while the wash stage efficiently removes resin residues before curing.
Designed for bigger models—compatible with printers such as Saturn Ultra and Mars series—the Mercury Plus 3.0 streamlines post-processing into a single workflow. The unit’s one-step approach reduces handling and potential damage during transfer between washing and curing. Users benefit from improved curing uniformity, with less need for manual repositioning. The combination of a larger wash capacity and 360° curing makes it a strong choice for makers who frequently print mid-size to large resin parts and require efficient throughput.
LET’S RESIN Curing Machine
LET’S RESIN’s curing machine emphasizes simplicity with a three-hour auto-curing cycle and a built-in large tray for batch processing. The device is designed for convenience: a single touch activates the auto-curing sequence, and the unit automatically stops when the process completes. It supports a broad range of molds, including 1-70 mm height and up to 30 cm diameter, making it suitable for jewelry, pyramids, coasters, or other decorative pieces. The curing cycle is engineered to maintain an even heat distribution, reducing the risk of surface texture distortion or bubbles.
The device offers three temperature settings—122°F, 140°F, and 158°F—and a six-hour timer, allowing users to tailor the heat profile to resin thickness and ambient conditions. Its heat-cycle technology aims to preserve surface integrity while delivering reliable curing across batches. The LET’S RESIN solution is particularly appealing to hobbyists who want predictable results without constant monitoring, especially for small to mid-sized resin projects that benefit from a consistent cure every time.
FAST MELT UV Resin Curing Box
The FAST MELT curing box focuses on UV resin curing with 80 high-quality LEDs emitting at 395 nm, delivering faster and more uniform cures for resin jewelry, coasters, and small decor items. Users can expect even exposure across surfaces, helping to minimize streaks or under-cured spots. A smart timer lets operators set durations in minutes, seconds, or hours, with a clear digital display updating in real time. A tray is included to organize parts during curing, enabling a smoother workflow for multi-piece projects and reducing the risk of resin drips on the work surface.
In practice, this curing box suits crafters who primarily work with UV resins and want precise timing control. The digital timer and tray support efficient batch processing, while the LED array provides consistent performance across multiple cures. It’s a practical addition for makers prioritizing speed and predictable UV curing across small-to-medium-sized items, especially when speed is a top priority in workshop settings or gift production lines.
Buying Guide
When choosing a resin curing machine, consider curing method, mold size, batch capacity, and ease of use. Hybrid units that combine hot air with UV light can cure epoxy resin quickly while delivering rapid UV hardening for UV resins, but they may consume more power and require more space. UV-only boxes excel at uniform light exposure but may take longer for thick layers. For epoxy molds, look for systems with temperature control, a stable platform, and a reliable timer.
- Curing method and speed: Decide whether you need a combo system (hot air + UV) or a dedicated UV curing box. If you frequently work with epoxy resins, a device with controlled heat and uniform exposure is essential.
- Tray size and mold capacity: Check the maximum mold dimensions and whether the tray can hold multiple small pieces for batch processing. Larger trays improve throughput for jewelry and decorative items.
- Automation vs. manual control: Auto-curing modes reduce monitoring time but may offer fewer fine-tuning options. Manual or programmable modes are ideal for advanced users with specific resin formulations.
- Uniform curing: Look for 360° illumination, rotating turntables, and reflective surfaces to ensure even curing across all angles.
- Compatibility with resin types: Some machines are optimized for epoxy resins, others for UV resins; a hybrid option provides flexibility across projects.
- Safety and reliability: Consider overheat protection, auto shutoff, stable bases, and easy-clean surfaces to minimize risk during frequent use.
- Maintenance and upgradability: Easy access to components, replaceable UV LEDs, and compatible accessories can extend a machine’s usefulness.
- Warranty and support: A robust warranty and responsive customer support can reduce downtime for hobbyists and professionals alike.
