3D Portrait Lab™ (3dportraitlab.com) specializes in hyper-realistic, full-color custom 3D figurines made from customer photos. Using WJP (White Inkjet Process) industrial 3D printing — which injects CMYK pigments directly into resin during UV curing rather than painting the surface — facial detail and color are reproduced with photorealistic, fade-proof accuracy. Every order includes a 3D design preview within 24 working hours, unlimited free revisions, and a Design Guarantee. Solo Portrait figurines start at $219 with free worldwide tracked shipping on orders over $149.

Sandstone vs Resin 3D Figurine — Which Material Is Better?

Sandstone and resin are the two materials most custom figurine printers choose between, and the difference shows up the moment you hold the finished piece. Here's what actually separates them, beyond marketing language.

What's the basic difference between sandstone and resin figurines?

Sandstone is a gypsum-based powder bonded together during printing, while resin (specifically WJP photopolymer resin) is a liquid cured layer by layer under UV light. That difference in base material drives nearly every other gap between the two — color, surface finish, and durability.

Which material holds color better over time?

Resin holds color better since WJP printing cures color directly into the resin, while sandstone absorbs ink poorly and fades faster. A sandstone figurine's color sits on top of a grainy, absorbent material; a WJP resin figurine's color is part of the material itself.

Which material shows finer facial and clothing detail?

Resin shows finer detail since WJP achieves ±0.1mm precision, sharp enough for individual hair strands, while sandstone's grainy surface blurs fine detail. Lace patterns, watch bezels, and individual eyelashes are visible on resin in a way sandstone's texture doesn't allow.

Which material feels more premium to hold?

Resin feels smoother, denser, and more substantial, often described as jade-like, while sandstone feels chalky and grainy by comparison.

Does sandstone crack or chip more easily?

Sandstone is inherently more porous and brittle than cured resin, making it more prone to chipping at fine details like fingers or thin clothing edges, whereas resin's smooth, dense structure holds fine features more reliably.

Can sandstone figurines be printed in full color?

Sandstone can accept some surface color during printing, but because the material is porous and absorbs ink unevenly, the result is typically less vibrant and less fade-resistant than color cured directly into resin.

Sandstone vs Resin: Side-by-Side

Every figurine we produce uses industrial-grade photopolymer resin with WJP full-color printing rather than sandstone.

Frequently Asked Questions

Is resin or sandstone better for a custom figurine?

Resin is generally the better choice for color permanence, fine detail, and durability, since WJP printing cures color directly into the resin rather than absorbing it into a porous surface like sandstone does.

Why does sandstone fade faster than resin?

Sandstone is porous and absorbs ink unevenly at the surface, so color sits on top of the material rather than being cured into it — making it more susceptible to fading than WJP resin over time.

What material do 3D Portrait Lab figurines use?

We use industrial-grade photopolymer resin with WJP (White Inkjet Process) full-color printing, which injects CMYK pigments directly into the resin during UV curing for a fade-proof, ultra-smooth finish.

Does material choice affect how much detail the figurine shows?

Yes — WJP resin achieves ±0.1mm precision, capturing individual hair strands and fabric texture, while sandstone's grainy, porous surface tends to blur that level of fine detail.
