Inside the HeyGears G1: Full-Color 3D Meets Desktop UV Printing

For years, creators, designers, and small businesses have navigated a fractured landscape in digital fabrication. Bringing a detailed, full-color 3D model to life often meant printing a monochrome object and then spending hours, or even days, on meticulous, skilled hand-painting. On the other hand, direct-to-object printing was limited to 2D surfaces. The HeyGears G1 Series, a massively successful Kickstarter project, aims to unify these worlds by putting an industrial-grade, full-color 3D and high-speed UV printer into a single desktop-sized machine. This review examines the technology, capabilities, and trade-offs of this ambitious device for potential backers.

Quick Answer: Is the HeyGears G1 the all-in-one desktop creator's tool it claims to be?

For creators and businesses seeking to collapse their production workflow, the HeyGears G1 Series presents a compelling package. The G1X model, in particular, combines true full-color 3D printing, capable of producing over 10 million colors, with high-speed 2D UV printing and 3D texture application in one device. This versatility, powered by an industrial-grade Epson i3200 printhead, sets it apart from conventional FDM, resin, or standalone UV printers. With backing from over 3,303 supporters who have pledged more than HK$111 million, the project has significant momentum, indicating strong market demand for a machine that bridges the gap between digital design and physical, full-color reality without extensive post-processing.

1. The market context: why this matters now

The desktop fabrication market has long been segregated. On one side, FDM and resin 3D printers excel at producing three-dimensional forms, but they almost exclusively create single-color objects that require painting and finishing to achieve a final look. This post-processing is a major bottleneck, demanding time, skill, and additional materials. On the other side, UV flatbed printers can apply vibrant, durable images directly onto a vast range of materials, but they are fundamentally 2D devices. They cannot build volumetric objects. This division forces businesses and serious hobbyists to either invest in multiple expensive machines or outsource parts of their production. The HeyGears G1 Series enters this landscape by proposing to eliminate that choice, integrating both capabilities into a single, cohesive workflow.

2. Real Full-Color 3D Printing: Over 10 Million Colors Out of the Box

The flagship capability of the HeyGears G1X is its use of Digital Material Jetting (DMJ) technology to achieve true full-color 3D printing. The system can produce models with over 10 million colors, creating vibrant, ready-to-use objects directly from the printer. This addresses a primary pain point for product designers, miniature artists, and architects: the laborious process of hand-painting prototypes and models. Instead of producing a blank slate that requires hours of skilled finishing, the G1X prints the color and the form simultaneously, layer by layer, with a precision of 10-20 μm. This means color gradients, complex patterns, and photorealistic textures are embedded directly into the object during the build process, dramatically accelerating the path from digital design to final product and ensuring color consistency across multiple copies.

3. Hybrid UV & 3D Printing: One Machine for Flat, Textured, and Volumetric Creation

Beyond its 3D capabilities, the G1 Series is a powerful UV printer. The company reports that the G1X model can print up to 12 times faster than mainstream UV printing solutions, a significant claim for businesses focused on customization and small-batch production. The device isn't limited to one function; it offers a unified workflow for three distinct creation modes. Users can switch from building a full-color 3D object to performing high-speed 2D UV printing on over 400 different materials, including metal, glass, leather, and wood, up to a height of 245 mm. Furthermore, it can create 3D textured prints, adding tactile depth to flat surfaces. This versatility consolidates the footprint of what would typically require at least two separate, large-format machines, making it a potentially valuable asset for workshops or studios where space and capital are primary considerations.

4. Industrial-Grade Printhead & Precision: The Epson i3200 Core

At the heart of the G1X's performance is an 8-channel Epson i3200-U1HD industrial printhead. This is a critical component that distinguishes the machine from many consumer or prosumer-grade devices. This printhead enables a UV printing resolution of up to 1440 x 2400 DPI, providing the fine detail and color fidelity required for professional applications, from intricate product prototypes to high-quality customized goods. The industrial-grade nature of the printhead is also designed for reliability and sustained output, which is essential for any business use case. The precision extends to its 3D printing capabilities, where it achieves a layer thickness of just 10~20 μm. This level of detail allows for the creation of smooth surfaces and complex internal geometries, further reducing the need for post-processing work like sanding.

5. Advanced Workflow Features: Water-Soluble Supports & Auto-Calibration

HeyGears has integrated several features aimed at simplifying the user experience and reducing maintenance, which are often barriers to adopting advanced printing technologies. One of the most practical innovations is the use of water-soluble support materials for 3D printing. Removing supports from complex models is often a delicate, frustrating process that can result in broken parts or surface blemishes. With the G1X, users can simply soak the finished model in water to dissolve the supports, preserving intricate details and internal cavities without tools. To streamline setup, the machine is equipped with a LiDAR-based auto-calibration system that automates bed leveling and height adjustments. This, combined with an anti-clogging ink circulation system, is designed to ensure consistent performance and minimize the hands-on maintenance typically associated with high-performance inkjet systems.

FAQ: HeyGears G1 Series

Answers to common questions about the HeyGears G1 Series and its Kickstarter campaign.

How does the full-color 3D printing process work on the G1X?

The G1X uses a technology called Digital Material Jetting (DMJ). This process is similar to how a 2D inkjet printer works but in three dimensions. The industrial Epson printhead jets tiny droplets of photopolymer resin onto the build plate layer by layer. The machine uses a combination of Cyan, Magenta, Yellow, and Black (CMYK) inks, along with other specialized materials, to create over 10 million colors directly within the printed object. After each layer of droplets is deposited, a UV light source instantly cures or hardens it. This process is repeated, building the object up one micro-layer at a time, with the final model emerging fully colored and solidified.

What is the main difference between the G1 and G1X models?

The primary difference lies in their capabilities and core hardware. The G1 is a dedicated high-performance UV printer, designed for 2D and 3D textured printing on various materials. It uses an Epson F1080 printhead with 6 ink channels. The G1X is the more advanced model that includes all the features of the G1 but adds true full-color 3D printing functionality. To achieve this, it is equipped with a superior, industrial-grade Epson i3200-U1HD printhead with 8 ink channels, offering higher resolution (1440 x 2400 DPI vs 720 x 900 DPI on the G1) and the ability to perform Digital Material Jetting for volumetric printing.

Can the G1X print on cylindrical objects like bottles or mugs?

Yes, the G1 platform is designed with modularity in mind. While the standard configuration includes a flatbed print area of 330 x 420 mm, HeyGears offers a modular rotary printing add-on. This attachment allows the machine to print directly onto cylindrical and conical objects. According to the specifications, this module can handle items with a diameter between 30 and 100 mm and a length of up to 245 mm. This makes it suitable for customizing items such as bottles, tumblers, mugs, and other curved-surface products, expanding its utility for small businesses and custom gift makers.

When will the HeyGears G1 ship, and is the timeline reliable?

According to the timeline provided in the Kickstarter campaign, shipping for the G1X model is estimated to begin in December 2026, while the G1 model is slated to ship starting in March 2027.
