Choosing a multi-color 3D printer used to mean spending thousands of dollars on a machine that still required hours of tinkering. That era is over. Today’s consumer-grade multi-color printers ship with automatic material systems, high-speed CoreXY motion, and software ecosystems that make four-color (or even sixteen-color) prints nearly as simple as pressing “start.” But the two machines dominating this space — the Bambu Lab P1S Combo and the FlashForge AD5X — take meaningfully different approaches to speed, build volume, material handling, and ecosystem design. This guide breaks down their published specifications, aggregates what verified owners and expert reviewers consistently report, and helps you decide which printer delivers the most capability for every dollar you spend.
Best for: Hobbyists, makers, and small-business operators who want dependable multi-color prints with minimal fuss
Why Multi-Color Printing Matters
Multi-color 3D printing isn’t just about aesthetics — though vibrant, multi-hue models certainly look impressive. It also unlocks practical capabilities: printing dissolvable support interfaces for complex geometries, combining rigid and flexible filaments in a single part, and producing functional prototypes that communicate design intent far better than monochrome alternatives. For small businesses selling custom figurines, signage, or product prototypes, multi-color capability can eliminate painting and post-processing steps entirely.
The catch? Multi-color systems introduce complexity. Filament-swapping mechanisms generate waste (purge towers or purge blocks), add print time, and create new failure modes. The best machines minimize these trade-offs through smart engineering. Below, we evaluate two printers that do exactly that — and we identify where each one excels.

Key Specs to Compare Before You Buy
Before diving into individual reviews, here are the specifications that matter most when evaluating multi-color 3D printers:
- Color/Material Capacity: How many filaments can the system handle simultaneously? More slots mean more colors per print without manual intervention.
- Print Speed: Measured in mm/s, this determines how quickly the printer lays down material. Faster speeds reduce the time penalty of multi-color purge cycles.
- Build Volume: The maximum printable dimensions (L × W × H). Larger volumes let you print bigger parts or batch multiple smaller ones.
- Hotend Temperature: Higher max temperatures unlock engineering-grade filaments like nylon, polycarbonate, and carbon-fiber composites.
- Enclosure: A fully enclosed chamber retains heat, reducing warping with ABS, ASA, and other temperature-sensitive materials.
- Auto-Leveling & Calibration: Automated bed leveling and vibration compensation save setup time and improve first-layer adhesion.
- Connectivity & Software: Slicer compatibility, cloud printing, and camera monitoring affect day-to-day workflow.
Bambu Lab P1S Combo — The Multi-Color Benchmark
The Bambu Lab P1S Combo bundles the P1S enclosed CoreXY printer with Bambu’s Automatic Material System (AMS), creating a turnkey multi-color solution. The AMS unit holds four spools and supports daisy-chaining up to four AMS units for a maximum of 16 colors or materials in a single print — a specification that remains exceptional at this price point.
Specifications Breakdown
Bambu Lab lists the P1S at a maximum print speed of 500 mm/s with acceleration up to 20,000 mm/s². The build volume is 256 × 256 × 256 mm — a generous cube that handles most hobbyist and small-business projects. The fully enclosed chamber helps maintain stable temperatures for ABS, ASA, PA, and PC filaments, while the direct-drive extruder supports hotend temperatures up to 300 °C. Auto bed leveling, vibration compensation, and flow calibration are all handled automatically.
On the software side, Bambu Studio (the proprietary slicer) is well-regarded for its multi-color workflow: users assign colors to model regions, and the slicer automatically generates purge towers and tool-change sequences. The printer includes a built-in camera for remote monitoring via the Bambu Handy app or Bambu Cloud.
What Verified Owners and Reviewers Report
Across major review outlets and verified customer feedback, the P1S Combo is consistently praised for its out-of-box reliability. Reviewers frequently highlight that multi-color prints succeed on the first attempt with default slicer profiles — a rarity in the 3D printing world. Print quality at high speeds is described as excellent, with minimal ringing artifacts thanks to the input shaping system.
Common complaints center on the proprietary ecosystem: the AMS uses Bambu’s RFID-tagged spools for automatic filament identification, and while third-party filaments work, some users report occasional feeding issues with certain spool sizes. The purge waste generated during color changes is another frequent criticism — though this is inherent to any single-nozzle multi-color system, not unique to Bambu. A smaller subset of reviewers note that the enclosed design, while great for temperature-sensitive materials, can make mid-print adjustments less convenient.
Who Should Buy This
The P1S Combo is ideal for makers, hobbyists, and small-business operators who want the most proven, reliable multi-color 3D printing experience available at a consumer price. If you value a polished software ecosystem, extensive community support, and the ability to scale up to 16 colors, this is the machine to beat. It’s also an excellent choice for users who print with engineering-grade filaments regularly, thanks to the enclosed chamber and 300 °C hotend.
FlashForge AD5X — Speed and Volume Challenger
The FlashForge AD5X enters the multi-color arena with aggressive specifications designed to challenge established players. It’s a CoreXY machine rated at 600 mm/s maximum print speed — 20% faster than the P1S on paper — and it ships with a multi-color system that supports up to four filaments simultaneously. FlashForge has a long history in the consumer 3D printing space, and the AD5X represents their push into the high-speed, multi-material segment.
Specifications Breakdown
The AD5X’s headline spec is that 600 mm/s maximum speed, paired with a direct-drive extruder capable of reaching 300 °C. FlashForge emphasizes one-click auto leveling for quick setup, and the machine includes an enclosure for printing temperature-sensitive materials. The build volume, while not fully detailed in the truncated product listing, appears competitive based on the machine’s physical dimensions and FlashForge’s marketing materials.
The multi-color system supports four filaments, which covers the majority of multi-color print jobs (most decorative and functional multi-color models use two to four colors). While it doesn’t match the P1S Combo’s 16-color maximum, four colors handle the vast majority of real-world use cases.
What Verified Owners and Reviewers Report
As a newer entrant to the high-speed multi-color segment, the AD5X has a smaller body of verified reviews compared to the P1S Combo. Early adopters and tech reviewers generally praise the raw speed — the 600 mm/s capability translates to noticeably shorter print times on speed-optimized profiles, particularly for large single-color sections within a multi-color print. The auto-leveling system is described as straightforward and effective.
On the other hand, some reviewers note that FlashForge’s slicer software (FlashPrint) has historically lagged behind Bambu Studio and PrusaSlicer in terms of multi-color workflow polish. The community and third-party profile ecosystem is also less mature, meaning users may need to spend more time dialing in settings for specific filaments. A few early reviews mention that the multi-color system’s purge handling could be more efficient, though FlashForge has been releasing firmware updates to address this.
Who Should Buy This
The AD5X is a strong pick for buyers who prioritize raw print speed and are comfortable doing some profile tuning. If you’re an experienced 3D printing enthusiast who doesn’t mind a less polished software ecosystem in exchange for faster throughput, the AD5X delivers serious capability. It’s also worth considering if you primarily need four or fewer colors and want a machine from a well-established manufacturer with a track record of long-term firmware support. For buyers who want to explore how spec-driven purchasing decisions work across other product categories, our streaming stick buying guide applies a similar analytical framework.
Head-to-Head: Spec Comparison
Let’s put the numbers side by side to clarify where each machine leads:
| Specification | Bambu Lab P1S Combo | FlashForge AD5X |
|---|---|---|
| Max Print Speed | 500 mm/s | 600 mm/s |
| Max Colors (Single Print) | 16 (with 4× AMS) | 4 |
| Hotend Max Temp | 300 °C | 300 °C |
| Enclosure | Yes (fully enclosed) | Yes |
| Auto Leveling | Yes (+ vibration comp.) | Yes (1-click) |
| Direct Drive Extruder | Yes | Yes |
| Remote Monitoring | Built-in camera + app | Varies by configuration |
| Slicer Software | Bambu Studio | FlashPrint |
Speed vs. Color Capacity
The AD5X wins on raw speed (600 vs. 500 mm/s), but the P1S Combo wins decisively on color capacity (16 vs. 4). For most users, the practical speed difference is modest — both machines are dramatically faster than budget printers — while the color capacity gap is significant if you plan to print complex multi-color models like detailed figurines, geological maps, or branded merchandise.
Software Ecosystem
Bambu Studio is widely regarded as one of the best slicers available, with deep multi-color integration, automatic purge optimization, and a large library of community-tested profiles. FlashPrint is functional but less polished for multi-color workflows. This is a meaningful differentiator for users who want to minimize time spent on slicer configuration.
Reliability and Community
The P1S Combo benefits from a massive user community, extensive YouTube tutorial coverage, and a well-documented troubleshooting knowledge base. The AD5X, being newer, has a growing but smaller community. For first-time multi-color printer buyers, this ecosystem advantage can save significant time and frustration.
Purge Waste: The Hidden Cost of Multi-Color Printing
Both of these printers use a single-nozzle design with a filament-swapping mechanism. Every time the printer changes colors, it must purge the previous color from the nozzle — typically by extruding a block or tower of waste material. This purge waste adds material cost and print time to every multi-color job.
The amount of waste depends on the number of color changes, the colors involved (switching from dark to light requires more purging), and the slicer’s optimization settings. Experienced users report that a typical four-color print can generate 20-40 grams of purge waste, though this varies widely. Both Bambu Studio and FlashPrint offer settings to minimize purge volume, and some advanced users route purge material into infill to reduce waste further.
This is an important cost consideration: if you’re printing multi-color models daily for a small business, purge waste can add up to several kilograms of filament per month. Factor this into your operating cost calculations.
Which Printer Delivers More Value?
Defining “value” depends on your priorities:
- If you want the most colors per print and the smoothest out-of-box experience, the Bambu Lab P1S Combo is the clear winner. Its 16-color capability, polished software, and proven reliability make it the safer investment for most buyers.
- If you prioritize raw speed and are comfortable with a less mature multi-color ecosystem, the FlashForge AD5X offers a compelling alternative with its 600 mm/s capability and competitive feature set.
- If you’re a beginner to 3D printing, the P1S Combo’s extensive community resources and automated calibration features reduce the learning curve significantly.
- If you’re an experienced maker who enjoys tuning profiles and wants the fastest possible throughput, the AD5X’s speed advantage may justify the trade-offs in software polish.
For most buyers reading a multi-color 3D printer buying guide, the Bambu Lab P1S Combo represents the strongest overall value proposition — not because it’s the cheapest or the fastest, but because it delivers the most complete, reliable, and scalable multi-color printing experience available at a consumer price point.
Frequently Asked Questions
Can I use third-party filament with these printers?
Yes, both printers accept standard 1.75 mm filament from any manufacturer. The Bambu Lab P1S Combo uses RFID-tagged spools for automatic identification, but third-party filaments work — you just configure the material settings manually in the slicer.
How much purge waste should I expect?
Purge waste varies by model complexity and color count. A typical four-color print may generate 20-40 grams of waste, though slicer optimization and techniques like flushing into infill can reduce this significantly.
Do I need an enclosure for multi-color printing?
Both printers include enclosures, which is ideal. An enclosure isn’t strictly necessary for PLA, but it’s essential for ABS, ASA, nylon, and polycarbonate — materials that warp without stable chamber temperatures.
Is 500 mm/s vs. 600 mm/s a noticeable difference?
In practice, the difference is modest. Real-world print speeds are often limited by acceleration, cooling, and the geometry of the part rather than the maximum advertised speed. Both machines are dramatically faster than older-generation printers.
