Micro 3D Printing is an advanced form of additive manufacturing used to produce extremely small, highly detailed parts. We offer Micro 3D Printing (micro SLA) with a resolution down to 10 microns, allowing for intricate parts with exceptional accuracy and surface detail.

Unlike SLS or SLA, Micro 3D Printing delivers much higher resolution and detail. Our microArch S240 3D printer, manufactured by Boston Micro Fabrication, cures fine layers of resin using light projection. This enables feature-rich components with very fine tolerances making it ideal for applications where standard resolution simply isn’t fine enough.

Micro 3D Printing is ideal for:

• Small, detailed engineering components
• Miniature housings or enclosures
• Medical and dental parts
• Microfluidic and research tools
• Watch and jewellery prototypes
• Electronic and sensor housings

If your part requires fine detail and a smooth surface finish, Micro 3D Printing is likely to be a strong fit.

This technology is particularly valuable to:

• Medical and dental sectors (for accurate tools, guides and components)
• Product design and development (especially in wearables, optics or handhelds)
• R&D teams working on next-generation miniaturised devices
• Watchmaking and jewellery (where fine detailing is essential)

Our Micro 3D Printing service offers exceptional accuracy and detail, with:

• Layer heights typically set at 10 or 20 microns
• The ability to fine-tune layer heights for specific features — for example, adjusting to an odd value such as 12 microns to maintain accuracy on a delicate feature that might otherwise be missed by other technologies
• Resolution down to 10 microns, with crisp edges and fine detail on miniature parts
• Thin walls and tight tolerances ideal for functional prototypes and trial-fit components

This level of control ensures outstanding accuracy, even for the most intricate or high-precision designs.

We use specially formulated engineering resins suitable for fine-feature prototyping:

• Matrix HTL: A high-temp, low-viscosity engineering material with excellent strength and rigidity. Finished parts can withstand temperatures up to 114°C, making them ideal for demanding environments.
• Matrix BIO: A biocompatible resin suited for non-implantable medical applications. This material is sterilisation-friendly and has passed multiple ISO 10993 biocompatibility tests.
• Matrix HTA300: Industry-leading, ultra-high temperature resistant rigid plastic suitable for the harshest thermal environments.

Download our datasheets to learn more about these materials.

The key consideration is size:

• The build envelope is 100 x 100 x 75 mm which is smaller than with standard SLA or SLS.
• Wall thicknesses need to be optimised for fine resin curing

We can advise on best practice to ensure your part prints successfully.

We recommend choose our P1 finishing process, which is the removeal of support witness marks. Learn more about our finishing options.
