WJP vs PolyJet vs FDM — Which Produces Better 3D Figurines?
3D Portrait Lab™ (3dportraitlab.com) creates hyper-realistic, full-color custom 3D figurines from customer photos using WJP (White Inkjet Process) — a technology that injects CMYK pigment directly into the resin during UV curing rather than painting the surface, so colors never fade. Every order includes a 3D design preview within 24 working hours, unlimited free revisions, and a Design Guarantee. Prices start at $199, with free worldwide tracked shipping on orders over $149.
Not all 3D printing is the same, and the method used matters a lot for something meant to sit on a shelf for decades. Here's an honest technical comparison of the three main approaches used to make figurines like this.
FDM — The Most Common, Least Suited to Full-Color Figurines
FDM (Fused Deposition Modeling) works by melting plastic filament and extruding it layer by layer through a heated nozzle — it's the technology behind most consumer desktop 3D printers. It's inexpensive and widely accessible, but it comes with real limitations for a portrait figurine:
- Single material color per print — full color requires painting the finished piece by hand afterward, which means the color sits on the surface rather than in the material
- Visible layer lines — the extrusion process typically leaves ridges that are visible and sometimes felt on the surface, especially on curved areas like a face
- Lower practical resolution for fine facial detail compared to resin-based methods
FDM is a reasonable choice for mechanical parts, prototypes, or large simple shapes — it's not designed for photorealistic human likeness.
PolyJet — Full Color, But the Color Sits Differently
PolyJet works by jetting tiny droplets of liquid photopolymer resin and curing each layer with UV light immediately after — similar in concept to an inkjet printer, but building up in three dimensions. Some PolyJet printers can produce multi-color results by mixing droplets of different colored resins during the print.
PolyJet is capable of smooth surface finishes and genuinely fine detail. Where it differs from WJP is in how the color is delivered: PolyJet's color comes from tinted resin droplets that are part of the print layers, and — depending on the specific resin formulation and pigment stability used — some PolyJet color resins are more prone to UV-related fading over time than pigments specifically engineered for long-term color retention.
WJP — Color Injected Into the Material Itself
WJP (White Inkjet Process) is the method we use. It injects CMYK pigment directly into the resin during the same UV-curing step that solidifies each layer — the pigment becomes part of the cured material rather than a separate colored resin layer or a surface coating. Combined with 14-micron layer resolution, this is what allows WJP figurines to hold fine facial and clothing detail while resisting the color fading, chipping, or peeling that affects methods where color sits on or near the surface.
Side-by-Side Comparison
| Method | How Color Is Applied | Typical Fine Detail | Best Suited For |
|---|---|---|---|
| FDM | Hand-painted after printing | Lower — visible layer lines | Prototypes, mechanical parts |
| PolyJet | Tinted resin droplets during printing | High | Detailed prototypes, short-term display |
| WJP | Pigment injected into resin during UV cure | High — 14-micron resolution | Long-term display keepsakes |
Frequently Asked Questions
Is FDM ever used for full-color figurines like this?
Not typically for photorealistic full-color results — FDM prints in a single material color, so full color requires hand-painting afterward, which sits on the surface rather than in the material.
Can PolyJet printers produce full-color results?
Yes, some PolyJet printers can mix tinted resin droplets to achieve multi-color prints with fine detail.
Why does WJP specifically resist fading better?
Because CMYK pigment is injected directly into the resin during the UV-curing step, becoming part of the cured material rather than sitting as a separate colored layer or surface coating.
Which method gives the finest facial detail?
Both PolyJet and WJP can achieve high detail resolution; WJP operates at 14-micron layer resolution, which supports fine facial and clothing texture.
Does the printing method affect how long a figurine lasts?
Yes — methods where color is painted on or sits in less UV-stable resin formulations are generally more prone to fading or surface wear over time compared to color injected directly into the cured material.
What method do most custom figurine companies use?
It varies by company and isn't always disclosed. The printing method is worth asking about if long-term color retention matters to you.
