Inside the Carbon 3D Printing DLS™ Process
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.
How Light Shapes Matter: The CLIP™ Process
with Carbon 3D printing
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.
Engineering Design, Redefined
Modern CAD and simulation software allow engineers and designers to push the limits of creativity—and Carbon 3D DLS™ brings those designs to life faster than ever before.
The process enables geometries impossible with traditional manufacturing, supporting lightweight structures, custom lattice patterns, and advanced functional designs.

Lattice 3D Print with Carbon DLS™: Engineering Complexity at Production Scale
Lattice 3D printing represents one of the most strategically valuable capabilities Carbon DLS™ brings to industrial manufacturing. A 3D printed lattice structure is not simply a lightweight infill pattern: it is a precisely engineered geometry where cell size, strut diameter, and density gradients are calibrated to deliver specific mechanical behaviors—such as controlled stiffness, energy absorption, or thermal management—within a single component.
Prototek’s engineering team designs these complex geometries using Carbon Design Engine, the DfAM software developed specifically for DLS™ workflows. This allows us to create variable-density lattice structures where different zones of the same part exhibit different mechanical responses (softer for comfort, stiffer for load-bearing) without assembly or adhesives.
Industrial applications of our lattice 3D print solutions include cycling saddle padding for Selle Italia, rowing seat pads for Filippi, helmet liner systems, and custom cushioning for automotive interiors. In each case, we achieve performance that conventional foam or injection-molded thermoplastics cannot replicate, with consistent repeatability from tens to thousands of units.
Carbon 3D Technology: Redefining Polymer Additive Manufacturing
Carbon 3D technology has fundamentally shifted the benchmark for industrial production. While conventional resin-based printing produces brittle, anisotropic parts with limited long-term stability, Carbon’s Digital Light Synthesis™ delivers fully isotropic components with injection-mold-quality surface finishes and certified mechanical properties.
The material portfolio gives engineers access to a broad range of functional polymers within a single platform. A component produced in EPX 82 epoxy resin behaves structurally like a glass-filled thermoplastic, while the same geometry printed in EPU 46 delivers controlled energy return.
As a leading European Carbon partner—with seven active printers operating 24/5—Prototek brings this capability to clients across automotive, aerospace, medical devices, and industrial machinery. Whether you need a single validated prototype or a certified production batch, our infrastructure is sized to deliver.
Carbon DLS 3D Printing: Industrial-Grade Production
Carbon DLS™ 3D printing has become the preferred platform for engineering teams requiring the mechanical performance of injection molding combined with the tooling-free economics of additive manufacturing.
The industrial relevance of Carbon DLS™ 3D printing lies in three key advantages:
Fully Isotropic Performance: Unlike FDM or standard SLA, DLS ensures consistent mechanical properties in every direction, which is critical for end-use components exposed to multi-directional loads.
Unrestricted Design Freedom: Rapid iteration during development without the geometric limitations imposed by traditional molding.
Production Scalability: Prototype, validate, and serially manufacture components using the exact same materials and process chain.
With a dedicated DfAM engineering team optimizing every geometry before production, Prototek offers far more than machine capacity: we provide a complete engineering and manufacturing partnership tailored for the European market.

Carbon Digital Light Synthesis™: The Science Behind the Process
Carbon Digital Light Synthesis™ is the proprietary process that permanently changed the mechanical performance ceiling of polymer 3D printing. The technology operates through a dual-cure material system that eliminates the historical trade-offs of additive manufacturing.
The CLIP™ Principle: First, UV light is projected through an oxygen-permeable window, photopolymerizing the resin. An oxygen-rich “dead zone” prevents premature curing, allowing the part to be continuously extracted upward rather than built layer by layer. This eliminates inter-layer weaknesses.
Thermal Post-Cure: Second, a controlled baking process activates a secondary chemical reaction within Carbon’s dual-cure resins. This converts the printed part into a stable, interpenetrating polymer network with predictable, long-term mechanical behavior.
The result is a component that combines the geometric complexity of resin printing with the structural integrity of engineering thermoplastics.
