HeyGears G1 vs Bambu Lab A1 Mini vs Mosaic Palette 3 Pro: Full-Color 3D Printing Showdown

The Full-Color Desktop Revolution

Three different approaches to full-color 3D printing just landed on the desktop market, each with a radically different philosophy. We break down the specs, workflows, and real-world trade-offs.

HeyGears G1: The All-in-One Color Platform

Price: $1,999 (Super Early Bird, Kickstarter)
Technology: Precision Piezo Inkjet + UV curing
Resolution: Up to 1440 x 2400 DPI, 3.9-picoliter droplets
Build volume: Not specified (desktop unit)
Key features: Full-color 3D printing, 2D UV printing on 400+ substrates, water-soluble supports, Epson I3200 printhead, integrated white-ink circulation, automatic printhead cleaning
Workflow: HeyVerse + Blueprint Studio software with AI-assisted model generation from text or images

The G1 is the most ambitious: it combines 3D texture printing, full-color 3D printing, and 2D UV printing into one machine. No painting steps, no assembly — objects come off the build plate looking finished. The G1X variant adds transparent material support and runs three operational modes from one platform.

Bambu Lab A1 Mini + AMS: Multi-Color FDM

Price: ~$300 (printer) + $299 (AMS) = ~$600
Technology: FDM with Automatic Material System (4 filaments)
Build volume: 192 x 192 x 180 mm
Key features: Enclosed, auto-leveling, multi-material support, 4-color printing via AMS, active chamber temperature control
Workflow: Bambu Studio slicer with paint-on support generation, automatic calibration

The A1 Mini takes the FDM route to color: print layer by layer with up to 4 filaments, relying on the AMS to swap colors mid-print. It's the most affordable entry into multi-color, but you're limited to 4 colors and the layer-line aesthetic of FDM.

Mosaic Palette 3 Pro: Universal Filament Splicer

Price: ~$699
Technology: Filament splicing (works with any FDM printer)
Colors: Up to 8 filaments simultaneously
Key features: Pre-cut filament spools, automatic splicing, works with any printer, cloud-connected calibration
Workflow: Mosaic Canvas software generates spliced G-code, feeds a single strand to your existing printer

The Palette 3 Pro doesn't sell you a printer — it makes any FDM printer multi-color capable by splicing filaments together before they enter your extruder. More flexible than being locked into one ecosystem, but adds complexity and a second machine to your setup.

Head-to-Head Comparison

Who Should Buy What

Choose the HeyGears G1 if: You're a small business or creator producing full-color figurines, collectibles, or product prototypes. You want finished-looking parts with no painting. The $2K price tag is justified by eliminating post-processing time.

Choose the Bambu A1 Mini + AMS if: You want an affordable, reliable entry into multi-color printing. You're already in the Bambu ecosystem or want the simplest setup. You don't need photorealistic color gradients.

Choose the Mosaic Palette 3 Pro if: You already have a favorite FDM printer and want to add multi-color capability without buying a new machine. You need more than 4 colors and don't mind the extra complexity.

The Bottom Line

Full-color 3D printing is no longer just for industrial service bureaus. The HeyGears G1 represents a fundamentally different approach — inkjet-based color that rivals traditional manufacturing in finish quality. But at $2K, it's a specialist tool. For most makers, the Bambu A1 Mini + AMS remains the sweet spot for multi-color FDM. The Palette 3 Pro fills a niche for those who want flexibility across any printer.
