A digital representation of a 3D object that contains all the information needed to create the object

A process where an object is built layer by layer using a UV laser and a photopolymer resin

A liquid material that solidifies when exposed to UV light

The platform that holds the object during the printing process and moves downwards after each layer is cured

The process of exposing a layer of resin to UV light to harden it into a solid layer

The process of removing excess resin and applying fresh resin to the surface after each layer is cured

A series of processes applied to the printed object after it is finished to improve its quality and durability

Ensuring the machine's accuracy and precision by setting up the laser source, filling the resin tank, and calibrating the platform

Creating a digital representation of the object you want to print using software like CAD.

Converting the 3D model into an STL file, which is a language 3D printers understand.

Slicing software divides the 3D model into thin layers. Each layer represents a cross-section and instructs the printer on material deposition.

Preparing the 3D printer includes loading the material, calibrating settings, and ensuring proper alignment and cleanliness of the bed.

The printer follows the sliced model's instructions and deposits material layer by layer to build the object.

A 3D model is represented as a collection of triangles in the STL format.

Computer-aided design (CAD) software is used to create digital 3D models.

The printer follows the layer by layer instructions from the sliced model and uses a toolpath to deposit material.

The process of dividing a 3D model into thin, horizontal slices that represent layers of the final object.

The path that the printer's nozzle or laser follows to deposit material, including the outer perimeter and inner fill patterns.

The structures generated by slicing software to support overhanging parts during printing, preventing them from collapsing.

A machine language that instructs the 3D printer on how to move its axes and deposit material according to the toolpath.

A 3D printing technology that cures liquid photopolymer resin layer by layer using a digital light projector.

The transformation of a liquid resin into a solid state when exposed to specific wavelengths of light.

The container that holds the liquid resin in DLP 3D printing.

A manufacturing method that builds objects layer by layer from a digital model, starting with a CAD design.

A manufacturing process where material is removed from a larger workpiece using cutting tools based on a CAD-generated path. It involves operations like milling and drilling.

A 3D metal printing technique that uses a wire as feedstock and deposits it onto a substrate layer by layer using a laser.

The ability to create objects with intricate shapes and complex internal structures.

A drawback of WAAM where the range of materials that can be used is limited compared to other methods.

A challenge faced by WAAM in maintaining precision and quality when producing smaller components.

A major benefit of WAAM allowing for high deposition rates, making it efficient for large-scale components.

An advantage of WAAM offering a cost-effective alternative to traditional manufacturing methods.

A 3D printing technique that uses a projector to cure liquid resin layer by layer, creating detailed and smooth objects.

A component in DLP 3D printers that projects the image of each layer onto the liquid resin. It allows for precise control over the curing process.

A 3D printing technology that uses a heated nozzle to extrude melted plastic filament onto a build platform, layer by layer, to build an object.

The ability to print objects with intricate details and complex geometries.

The speed at which the 3D printer can build an object. DLP 3D printers are known for their fast printing speeds.

The size of the printing area on the 3D printer. While DLP 3D printers have many advantages, some are limited by the size of objects they can print.

The ability of a 3D printer to handle different types of materials. DLP 3D printers can be used for various materials, from rigid plastics to flexible polymers and even bioinks.

The deposition process in WLAM allows for controlling the thickness and shape of each layer of material deposited by the laser. This control is crucial for achieving desired part geometry and specifications.

The molten metal solidifies rapidly as it cools, impacting the microstructure and properties of the final 3D printed part. The speed at which it solidifies can influence strength, toughness, and other characteristics.

Processes applied after the initial 3D printing to refine the part's final properties and appearance. Examples include heat treatments to alter strength or machining to achieve precise dimensions.

WLAM processes can create parts much faster than powder-based additive manufacturing, making it suitable for creating larger quantities of parts.

Using wire as a feedstock is more cost-effective than using powder, and the equipment involved in WLAM generally costs less than other advanced laser-based 3D printing.

WLAM enables the creation of complex 3D shapes and internal structures that would be impossible to achieve with traditional manufacturing methods. This is useful for lightweight designs and integrating functionality.

Since wire is used as feedstock, there is no material waste during the process. This is unlike powder-based 3D printing where some powder is not used in the final part.

The laser offers precise control over the heat input, which minimizes distortion and improves the final part's mechanical properties.
