What is Carbon 3D Printing DLS™ Technology?
Carbon DLS™ (Digital Light Synthesis™) is an advanced additive manufacturing process that uses digital UV light projection and programmable liquid resins to create high-performance polymer parts. Unlike conventional resin 3D printing technologies, Carbon uses the CLIP™ (Continuous Liquid Interface Production) process, which builds components continuously rather than layer by layer.
This process enables:
- Consistent mechanical properties in all directions
- Smooth surface finishes
- Reduced layer-related weaknesses
- Production of functional parts suitable for real-world applications
After printing, Carbon materials undergo a thermal post-curing process that activates their final mechanical properties, creating durable components with performance closer to engineering thermoplastics.

How Carbon 3D DLS™ Technology Works
The Digital Light Synthesis™ process is based on Continuous Liquid Interface Production™ (CLIP™) and Carbon’s programmable liquid resins. CLIP™ utilizes digital light projection through an oxygen-permeable window, a concept first introduced in a groundbreaking Science journal publication.
Traditional resin 3D printing produces parts that are often brittle and prone to aging or crystallization. Carbon’s dual-component materials overcome this limitation: after the initial UV photopolymerization, a thermal post-cure chemically activates a secondary reaction that transforms the printed part into a true thermoplastic-equivalent structure.

The CLIP™ Continuous Liquid Interface Production Process
CLIP™ is a photochemical process that uses UV light to solidify a specialized liquid resin. The UV image sequence is projected through an oxygen-permeable window beneath the resin tray, creating a continuous build zone where the part forms seamlessly.
Unlike conventional layer-by-layer DLP printing, CLIP™ continuously pulls the solid part upward, producing isotropic components with uniform density and no visible layer lines. This continuous process eliminates lateral stress during printing and allows faster, smoother, and stronger part creation.
Core Components of the System
- Build Platform
- Resin Vat
- Oxygen-Permeable Window
- Dead Zone (Continuous Build Interface)
- UV Light Engine and Motorized Lift System.
dead zone
The “dead zone” is key to the process; it’s the microscopic gap between the window and the part being printed.
This oxygen-rich zone prevents the resin from curing directly on the window, enabling constant resin flow and continuous printing.

Thermal Activation: achieving true Thermoplastic Properties
At the end of the printing phase, the components are UV-cured and partially solidified. During the thermal post-cure, the second reactive component in Carbon’s resin activates, completing the polymerization and producing stable, strong, and durable parts.
This dual-stage curing process ensures outstanding mechanical performance, dimensional stability, and long-term resistance—qualities previously unachievable in resin-based 3D printing.
Exceptional Surface Quality and Mechanical Performance
Traditional resin 3D prints often suffer from weakness along the Z-axis due to their layer-by-layer construction.
The continuous build process guarantees:
Smooth, injection-mold-quality surface finishes
High accuracy and detail definition
Superior isotropy and durability
This makes Carbon 3D DLS™ ideal not only for prototypes but also for end-use industrial production.

Digital Light Synthesis™
Carbon 3D DLS™ (Digital Light Synthesis™) produces isotropic parts with consistent density and strength in every direction.

DLP 3D PRINTING
3D-printed parts are notoriously inconsistent. Their mechanical properties vary depending on the direction in which the parts were printed due to the layer-by-layer construction.
Carbon DLS™ vs Traditional Resin 3D Printing
Traditional resin technologies often show differences in mechanical properties depending on print direction.
Carbon DLS™ produces more uniform parts thanks to its continuous build process, enabling isotropic performance closer to injection-moulded components.
