Micro DLP Printing Process

Micro digital light processing (DLP) utilizes UV light to rapidly photopolymerize layers of resin. This 3D printing DLP technology produces parts at a resolution of 1.9 microns and with a layer thickness down to 1 micron. By comparison, traditional DLP 3D printing technologies typically achieve resolutions between 80 and 100 microns.

Micro DLP Printing Advantages

High-resolution output for miniature features
Lower cost—no need for tooling
Diverse applications across industries
Unparalleled precision for micro-scale parts

Micro DLP Printing Best Uses

Materials for Micro DLP Printing

TTH currently offers three proprietary epoxy-based materials: D-810, T-700, and Performance P-900, each engineered to perform reliably in micro DLP printing environments.

D-810 is similar to Acrylonitrile Butadiene Styrene (ABS), commonly used in 3D printing. It provides strength and flexibility for structural applications.

Performance P-900 is a ceramic-filled epoxy that mimics engineered plastics used in injection molding. It tolerates high temperatures and resists excessive wear, making it ideal for demanding micro-scale applications.

T-700 is a clear, non-cytotoxic material similar to PMMA (polymethylmethacrylate), offering transparency for microfluidics and medical device components.

Nano Dimension, the creator of the Fabrica Tera 25, continues to expand its material development pipeline. In addition to material advancements, surface finish capabilities are evolving. TTH has successfully tested metal plating on D-810 material, increasing part strength and functional usability.

Micro DLP Printing Equipment

TTH uses the Fabrica Tera 25 from Nano Dimension, a micro DLP system designed for extremely fine feature resolution. Unlike traditional systems, this equipment supports micro DLP 3D printing at significantly smaller scales, producing precise miniature components.

The Fabrica Tera 25 prints at resolutions between 1–5 microns—approximately one-tenth the thickness of a human hair. With layer thicknesses down to 1 micron and tolerances of ±1 micron, entire assemblies can be printed in a single build. These capabilities make micro DLP printing especially valuable for medical device and microfluidics manufacturing, where channels and holes under half a millimeter require consistent clearance.

Demand for micro DLP printing equipment continues to grow, with production parts delivering measurable value across global applications.

Micro DLP Design & Build Guidelines

Miniature-scale 3D printing supports industries such as medical devices, electronics, automotive, aerospace, and defense. When planning micro 3D printing projects, consider the following guidelines:

Layer Thickness: 1–5 microns
Surface Roughness (RMS): 0.8 micron
Standard Lead Time: 3–5 days
Tolerances: ±1 micron
Build Speed: 1 mm height per hour
Build Volume: 50 mm × 50 mm × 100 mm

What Our Partners Are Saying

I’ve been working with TTH for 20+ years. That spans 2 employers for me. In the case of both employers, I was just one of several of my colleagues that trusted TTH for prototype and production parts. I think that alone speaks volumes. I don’t know anyone that returns to a vendor that lets them down, and when you keep coming back after 20 years, it tells a pretty compelling story.

TTH has always lived up to its name by staying on the leading edge of technology. They were the first to introduce me to SLS parts a couple of decades ago allowing me to perform functional tests with printed parts which enabled us to shorten time to market. Relatively recently, they introduced me to Carbon DLS and printed urethane parts that we ended up using in production, solving some very challenging technical issues and freeing us from the confines of tooled parts. TTH provides more than just prototype and production parts, they provide solutions and a relationship that in my experience has been tremendously beneficial.

-Steve R., Project Engineer, Consumer Products (Small Appliances)

Most of my 30 year career has been spent finding vendors that meet my Cost, Service, and Quality requirements. The number of suppliers that can meet those criteria for a sustainable period of time are few. TTH is one of those companies. The management team at TTH is always willing to work with us to improve efficiency and offer solutions that exceed our expectations. If you are looking for a partner, not just a supplier, the team at TTH will not disappoint.

Frequently Asked Questions

Q: What are micro 3D printing services and how do they differ from standard 3D printing?

A: Micro 3D printing services use high‑resolution technologies like Digital Light Processing (DLP) to produce extremely detailed parts with fine features and smooth surfaces that are too small or delicate for traditional 3D printing processes. This makes micro 3D printing ideal for precision components, small assemblies, and highly detailed prototypes.

Q: What is micro DLP and how does it work?

A: Micro DLP is a form of digital 3D printing that uses a projector to cure liquid resin layer by layer with focused light patterns. This enables TTH to achieve very high accuracy and surface quality on small, complex parts — often used in medical devices, micro‑mechanical parts, and detailed prototypes.

Q: What kinds of applications benefit from DLP 3D printing technology?

A: DLP 3D printing technology is especially beneficial for applications requiring fine detail, tight tolerances, and smooth finishes. Typical uses include miniatures, dental or medical components, jewelry patterns, microfluidic devices, and any small parts where precision and surface quality are critical.

Q: Why choose TTH for micro DLP 3D printing services?

A: TTH combines advanced micro DLP technology with engineering expertise and quality processes, offering reliable, high‑resolution 3D printing. Their capabilities allow customers to prototype and produce detailed parts with excellent dimensional accuracy and repeatability.
