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. Beyond color and detail, the choice affects production cost, shipping risk, and even how to tell which one you're actually being sent. Here's what 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. For how the two hold up on color and detail specifically, see the full material comparison over a 10-year span — the short version is that resin's color is cured into the material rather than sitting on a porous surface, so it doesn't fade the way sandstone does.

Why Do Some Custom Figurine Companies Use Sandstone Instead of Resin?

Sandstone printing (binder jetting) uses cheaper equipment and materials than full-color resin printing, which is why it's common among lower-cost or newer figurine makers — it's a lower barrier to entry, not a design choice made for the customer's benefit. Full-color resin printing at WJP's precision level requires industrial-grade equipment (like the Sailner systems used in our production) capable of injecting CMYK pigment during UV curing, which represents a significantly larger investment. When you see a figurine priced well below $100, sandstone construction is the more likely reason, not just a smaller markup.

How to Tell What Material You're Actually Being Sent

If you've already ordered from somewhere else and want to check what arrived, a few quick tests tell you which material you have:

• Surface feel: resin is smooth and slightly cool to the touch, almost jade-like; sandstone feels dry, slightly gritty, and chalky, closer to unglazed pottery.
• Weight for size: resin is noticeably denser — a resin figurine feels substantial for its size, while a same-sized sandstone piece feels lighter and hollow.
• Edge detail: look closely at fine features like fingers, individual hair strands, or fabric folds. Sharp, crisp edges indicate resin; slightly blurred or rounded-off fine detail indicates sandstone.
• Light test: hold the piece up to a bright light at an angle. Resin has a subtle sheen; sandstone stays completely matte with no reflection at all.

Which Material Ships Better?

Resin is significantly more impact-resistant in transit than sandstone. Sandstone's porous, brittle structure makes it prone to chipping at thin points — fingers, ears, raised details — if a package is dropped or mishandled during international shipping. Dense photopolymer resin absorbs minor impacts without the same fine-detail chipping risk, which matters more than it might seem for orders shipping internationally over 1–2 weeks of transit.

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 — consistent with the surface-feel test above.

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 — see the year-by-year durability breakdown for how that plays out over time.

Does Sandstone Crack or Chip More Easily?

Yes — 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, both in everyday handling and in shipping.

Every figurine we produce uses industrial-grade photopolymer resin with WJP full-color printing rather than sandstone. Start on our Solo Portrait page to see the difference for yourself, or read more about the technology in What Is WJP 3D Printing?

Frequently Asked Questions

Is resin or sandstone better for a custom figurine?

Resin is generally the better choice for color permanence, fine detail, shipping durability, and overall feel, since WJP printing cures color directly into a dense, non-porous material rather than a porous surface like sandstone.

Why do some companies still use sandstone?

Sandstone (binder jetting) equipment costs less than full-color resin printing systems, making it a lower barrier to entry for newer or budget figurine makers — not necessarily a choice made for durability or appearance.

How can I tell if a figurine I received is resin or sandstone?

Check the surface feel (resin is smooth and cool, sandstone is dry and chalky), weight (resin is denser), and edge sharpness on fine details (resin holds crisper detail).

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.
