Carbon DLS 3D Printing Services

Carbon DLS 3D Printing Process

Carbon Digital Light Synthesis (DLS) is a photochemical process that uses both light and oxygen to build parts. UV images generated by a digital light projector are projected through an oxygen-permeable window into a reservoir of UV-curable resin. Parts are built continuously in 25–100 micron layers, then washed, support-removed, and thermally cured to achieve final mechanical properties.

The result is production-ready parts delivered in days, not weeks, with exceptional surface finish and isotropic strength. Compared to SLA, FDM, and MJF, carbon DLS uses thermoset materials engineered for repeat production rather than one-off prototypes.

Frequently Asked Questions

Q: What is Carbon Digital Light Synthesis (DLS) 3D printing?

A: Carbon Digital Light Synthesis (DLS) is a high‑performance 3D printing technology that uses light and oxygen‑permeable optics to rapidly cure resin into strong, detailed parts. It bridges the gap between prototyping and production by delivering parts with excellent mechanical properties and fine surface quality.

Q: How does DLS 3D printing from Carbon differ from traditional 3D printing?

A: Unlike some traditional methods that build parts layer by layer with visible step lines, Carbon DLS produces smoother part surfaces and greater consistency. It also enables faster build speeds and uses engineered materials that can meet demanding functional and end‑use part requirements.

Q: What kinds of parts can be produced with Carbon DLS 3D printing?

A: With Carbon DLS, TTH can produce functional prototypes, production‑grade components, tooling, and customized parts that require durability, accuracy, and fine details. It’s ideal for applications across automotive, medical, consumer goods, and industrial markets.

Q: Why choose TTH for Carbon DLS 3D printing services?

A: TTH combines Carbon DLS technology with expert design and manufacturing support, ensuring parts are optimized for performance and manufacturability. Their advanced process control and quality systems deliver reliable additive manufacturing results for both prototyping and production runs.

What Our Partners Are Saying

I truly enjoy working with the team at The Technology House - it has been a true partnership. Their extensive knowledge in product development and manufacturing is beneficial not only to Carbon, but also to end customers looking for manufacturing help. The Vitamix success story with Carbon is one proof point of their incredible work. You won't be disappointed when working with The Technology House!

- Dana McCallum, Head of Market Development at Carbon, Inc.

I have partnered closely with TTH for over a year, and working with them has been a wonderful experience. Their entire team is always pleasant to work with, their project managers are incredibly knowledgeable, and their attention to quality and timeliness is best in class. I simply cannot recommend them highly enough for any project big or small.

- Jordan G., Additive Manufacturing Professional

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.
