Third-generation light-curing 3D printing technology

Third-generation light-curing 3D printing technology

CLIP, or Continuous Liquid Interface Manufacturing, is an innovative upgrade based on traditional SLA technology. It leverages the oxygen-inhibition polymerization effect of acrylates and introduces a transparent, breathable Teflon film at the bottom of the resin tank, allowing both light and oxygen to pass through simultaneously. By precisely controlling the amount and timing of oxygen entering the resin pool, a “dead zone” several dozen micrometers thick forms near the film—this zone is incapable of undergoing photopolymerization. Meanwhile, ultraviolet light causes the resin in the remaining areas to solidify, “growing” the printed object out of the liquid state.

LCD light-curing 3D printing technology, also known as mask-based stereolithography, is an emerging 3D printing technique. Similar to SLA and DLP technologies, LCD light-curing 3D printing works by using a light source to solidify liquid resin. However, its unique feature lies in the fact that the light source is controlled by an LCD screen. This technology leverages the imaging principle of liquid crystals: a computer program provides image signals that create selectively transparent areas on the LCD screen. Under the irradiation of ultraviolet (UV) light, the UV light passing through these transparent areas forms a UV-light image region, causing the liquid resin exposed to it to solidify. Meanwhile, the parts of the LCD screen that remain opaque cannot be cured by the UV light. The entire process proceeds layer by layer according to a pre-set 3D model; by sequentially stacking and solidifying these resin layers, a complete 3D-printed object is ultimately constructed.

Second-generation light-curing 3D printing technology

Digital Light Processing, or DLP for short, emerged more than a decade after the advent of SLA (Stereolithography) technology. It is a variant of SLA and shares a similar principle with SLA’s forming technology. This technology is also widely recognized in the industry as the second-generation photopolymerization-based additive manufacturing technique.

The earliest commercial 3D printing technology

The earliest commercial 3D printing technology

The stereolithography process, also known as stereolithographic fabrication and abbreviated as SLA, refers to a manufacturing method that uses ultraviolet light to induce a polymerization reaction in liquid photopolymer resin, thereby curing it layer by layer and producing a three-dimensional solid object. Parts fabricated using SLA exhibit high dimensional accuracy and represent one of the earliest commercially available 3D printing technologies.

Directed Energy Deposition 3D Printing

Directed energy deposition 3D printing technology is an additive manufacturing process that delivers raw materials—either in powder or wire form—to a substrate and uses a focused laser beam, electron beam, or plasma/arc energy source to melt the material, depositing it layer by layer in continuous fashion to form small molten pools.

Sheet lamination 3D printing

Sheet lamination 3D printing

Sheet lamination 3D printing is a technique that produces 3D objects by stacking and laminating extremely thin sheets of material—such as paper, plastic films, metal foils, or composite materials. The final shape is formed through mechanical cutting or laser cutting. Layers of different materials can be bonded together using various methods, including heating or ultrasonic bonding, depending on the specific material properties.

The fastest 3D printing method for materials such as metals and ceramics.

Binder jetting is a three-dimensional printing process that uses a liquid binder to bond powdered metal materials layer by layer, thereby creating solid, complex-shaped parts. This technology combines features of both powder-bed fusion and material jetting. In binder jetting, the binder is deposited onto a layer of powder, bonding individual areas together to form a solid part—one layer at a time. The materials most commonly used in binder jetting include granular metals, sand, and ceramics.
