01 / Why choose this material

Properties and uses
of white resin.

White stereolithography resin with ABS-like behavior. It comes out smooth and finely detailed, and it is the ideal base for painting. It is the only resin that prints parts up to 1,650 mm in one piece.

White resin is printed by stereolithography: an ultraviolet laser cures the resin layer by layer. The surface comes out smooth and the details sharp, which is why it is used to show the shape of a product or to paint it. It is the only resin that prints parts up to 1,650 mm in one piece. For parts that work, choose Multi Jet Fusion.

White resin applications

Appearance prototypes

Prototypes to show the shape and appearance of a product.

Models

Presentation and design validation models.

Parts for painting

Parts to be painted in the final color.

Presentation models

Large one-piece models for trade shows or clients.

02 / A choice based on usage

Choose white resin
based on your part.

These criteria help define the material, geometry, and working conditions before manufacturing.

01

For showing, not for working

It withstands 46 °C before deforming. Use it for models and appearance prototypes, not for parts in the sun, near heat, or under load.

02

Painting

It is the best base for painting in RAL or Pantone: the smooth surface needs little preparation.

03

Size

Up to 1,650 × 760 × 580 mm in one piece. Beyond that, it is printed in sections that are then joined.

The part's function is the starting point.

Indicate loads, temperature, environment, and appearance needed. If the drawing requires a specific grade, include it in the request.

03 / Finishing also counts

Finishes and appearance

Smooth surface typical of stereolithography. Support marks are sanded; layers may be visible on curved surfaces.

Reference images: material, geometry, and surface preparation influence the outcome. Special finishes are quoted upon request.

04 / From design to quote

SLA 3D printing
in white resin.

Stereolithography builds the white resin part layer by layer: an ultraviolet laser cures the liquid resin on a platform. The part grows on thin supports that are then removed and sanded, and it gets a final cure with ultraviolet light.

Upload a 3D model per part, for example in STEP or STL. SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, and 3DM files are also accepted. Add a PDF drawing with functional dimensions and assembly requirements.

Part tolerances

Printing tolerances depend on geometry, orientation, and material. Indicate assembly dimensions on a drawing for the team to confirm feasibility. CNC machining tolerances are not automatically applied.

Quantity and cost per part

The price per part usually varies little with quantity. Producing more units does not imply the volume savings achievable with machining or molds.

Quote in 24 hours

Parts from 7 working days after confirming the order. The quote specifies the lead time based on geometry, material, finish, and quantity.

How much it costs to manufacture

The price of your part
in white resin.

The price of printing white resin depends on material volume, geometry, build orientation, and post-processing. Quantity usually reduces the unit cost only slightly.

Check the catalog example to compare materials. To know the cost of your design, request a quote with your 3D file.

Frequently asked questions

Before manufacturing
in white resin.

Properties, applications, and manufacturing: answers to prepare your request.

What is white resin and what are its properties?

White stereolithography resin with ABS-like behavior. It comes out smooth and finely detailed, and it is the ideal base for painting. It is the only resin that prints parts up to 1,650 mm in one piece. Photopolymer resin: it is not suitable for parts that work above 45 °C, in the sun for months, or under sustained loads. For functional parts, choose a Multi Jet Fusion material.

What parts can be manufactured in white resin?

You can manufacture appearance prototypes, models, parts for painting, and presentation models. Stereolithography allows validating the appearance and detail of a part without manufacturing a mold. Define the loads, environment, and finish so we can review the application.

What is the difference between printing in SLA resin and in PA12 MJF?

SLA resin comes out smoother and with more detail, but withstands less temperature and is more brittle. MJF PA12 is granular but tough and functional. Resin for showing; MJF for parts that work.

Can a white resin part be painted?

Yes, it is the best resin for painting. Proto&Go! paints it in RAL or Pantone with a matte, satin, or gloss finish. Specify the color when requesting the quote.

What is the maximum size of a white resin part?

Up to 1,650 × 760 × 580 mm in a single piece. The other two resins have a smaller maximum size.

How much does it cost to 3D print a white resin part?

The price of printing white resin depends on material volume, geometry, build orientation, and post-processing. Quantity usually reduces the unit cost only slightly. Upload the 3D file to the Proto&Go! platform to receive a quote with cost and lead time.

What tolerances can I request for a white resin part?

Printing tolerances depend on geometry, orientation, and material. Indicate assembly dimensions on a drawing for the team to confirm feasibility. CNC machining tolerances are not automatically applied.

What file do I need to manufacture a white resin part?

Upload a 3D model per part, for example in STEP or STL. SLDPRT, X_T, X_B, IPT, CATPART, PRT, SAT, and 3DM files are also accepted. Add a PDF drawing with functional dimensions and assembly requirements.
