What We Do

Singapore's Precision UV Printing Specialists

UV printing is a digital printing process where ultraviolet light instantly cures ink as it is applied, producing vibrant, high-resolution prints with exceptional adhesion and durability. Unlike conventional printing, there are no solvents and no drying time — ink solidifies on contact, locking in detail and colour fidelity.

At 3D Specialist, we apply UV printing directly onto 3D-printed parts and flat substrates including plastics, metals, glass, wood, and composites. This makes it ideal for adding branding, product markings, decorative graphics, and serial numbers to finished components with permanent, scratch-resistant results.

Whether you need a single branded prototype or a production run of marked components, our UV printing service delivers consistent, photographic-quality output on virtually any surface. We handle the complete workflow from substrate preparation to final quality inspection.

How It Works

The UV Printing Process

Step 01

Surface Preparation

The 3D part or substrate is cleaned and inspected to ensure optimal ink adhesion. Surface contamination, oils, or residues are removed before printing begins. This step is critical to achieving sharp, long-lasting results across all material types.

Step 02

Step 2 — UV ink application and instant curing

Print & Instant Cure

Our UV printer applies ink layer by layer at up to 1200 DPI. As each pass is deposited, integrated UV lamps cure the ink instantly — producing sharp edges, vibrant colours, and a surface that is immediately dry and handling-ready with no smudging or bleed.

Step 03

Step 3 — Quality inspection and finishing

Inspect & Finish

Printed parts are inspected for colour accuracy, edge definition, and adhesion quality. Where required, additional coatings or varnish layers are applied for enhanced gloss, matte finish, or scratch resistance before the finished pieces are packaged and delivered.

White Ink

White Ink UV Printing

Opaque base layer for dark and transparent surfaces

White ink is an essential capability for printing onto dark, black, or transparent substrates where CMYK alone would be invisible. We apply a white ink underbase before the colour layers, ensuring your graphics remain vibrant and fully opaque regardless of the surface beneath. White ink can also be used as the sole print layer for clean, minimal aesthetics.

UV varnish and gloss effects printing Singapore

Varnish & Effects

Varnish & Specialty Finishes

Gloss, matte, and tactile spot varnish effects

UV varnish layers add a premium dimension to printed parts, enabling gloss or matte coatings, selective spot varnish effects, and raised tactile textures. These finishes enhance both the visual and physical quality of your printed components, making them ideal for premium packaging, branded products, and presentation models.

Part Marking

Industrial Part Marking

Serial numbers, barcodes, and QR codes on components

UV printing is an effective solution for permanent part identification across industrial and commercial components. We print serial numbers, part codes, barcodes, QR codes, and compliance markings directly onto finished parts with precision and repeatability — no masks, no labels, no adhesive residue. Variable data printing allows each part to carry a unique identifier.

Advantages

Why UV Printing Outperforms

UV printing combines the quality of digital graphics with the permanence and speed of industrial manufacturing processes. It is the most versatile direct-to-object printing technology available for finished 3D parts and flat substrates.

High-Resolution Quality

Up to 1200 DPI output delivers crisp lines, photographic imagery, and fine text that conventional printing methods cannot achieve on rigid 3D substrates.

Durable, Scratch-Resistant

UV-cured ink forms a tough, chemically bonded layer resistant to scratches, fading, moisture, and environmental exposure — lasting far longer than stickers or pad printing.

Multi-Material Versatility

Print directly onto plastics, metals, glass, wood, acrylic, and composites with the same machine and process — no substrate-specific tooling or changeover delays.

Instant Cure & Fast Turnaround

UV inks cure immediately as they are applied. No drying time means parts are handling-ready right off the machine, enabling 1–2 day turnaround on most orders.

Eco-Friendly Process

UV inks contain no solvents and release negligible VOCs during curing. Instant cure also eliminates the energy consumption of conventional drying ovens.

Full Customisation

Variable data printing allows unique serial numbers, QR codes, or personalised designs on individual parts within the same batch — with no additional setup cost per variation.

We accept vector files (AI, EPS, PDF) and high-resolution raster files (PNG, TIFF, PSD) at a minimum of 300 DPI at final print size. For best results, supply artwork in CMYK colour mode with all fonts outlined. If you only have a low-resolution file, contact us first and we can advise on whether it's suitable or suggest workarounds.

Yes, absolutely. UV printing is well suited to finished 3D-printed parts across FDM, SLA, SLS, and MJF. The surface should be clean, dry, and reasonably smooth for best adhesion. For FDM parts with visible layer lines, light sanding or priming beforehand improves print quality significantly. We can advise on surface preparation as part of your order.

UV-cured inks form a chemically bonded layer that is significantly more durable than pad printing, screen printing, or label application. The cured ink is scratch-resistant, UV-stable (resistant to fading under light exposure), and water-resistant under normal conditions. For applications requiring even greater abrasion resistance, we can apply a clear protective varnish overcoat.

There is no strict minimum order quantity. We handle single-unit jobs for prototyping and sampling as well as production runs of hundreds of parts. Setup costs are minimal compared to screen printing or pad printing, which makes UV printing particularly cost-effective for short runs and variable data jobs where each part carries a unique identifier.

Yes, and this is a popular combined workflow. We 3D print your parts, apply any required post-processing such as sanding or priming, and then UV print your graphics or markings in a single order. This eliminates the need to coordinate multiple vendors and ensures the substrate is prepared correctly before printing. Contact us with your full requirements and we'll quote the complete pipeline.

Yes. White ink is available both as a full underbase layer for printing on dark substrates and as a standalone spot colour. Varnish options include high-gloss, soft-matte, and spot varnish for selective coating effects. Raised tactile varnish can also be applied for premium decorative finishes. Specify your requirements when requesting a quote and we'll confirm compatibility with your substrate.
