### Additive Manufacturing #

### Additive Manufacturing

Additive manufacturing is the process of creating a three #

dimensional object by adding material layer-by-layer. This technology is in contrast to traditional subtractive manufacturing methods, where material is removed from a solid block to create the desired object. Additive manufacturing is also commonly referred to as 3D printing.

### AM Facility #

The heat bed maintains a consistent temperature during the printing process, ensuring proper bonding between layers.

### Infill #

### Infill

Infill is the internal structure of a 3D print #

It is the material that is printed between the outer walls of a model, and it provides strength and support. Infill patterns and densities can be customized to optimize print time, strength, and weight.

### Layer Height #

### Layer Height

Layer height is the thickness of each layer in a 3D print #

Layer height affects the resolution, print time, and surface finish of a 3D print. Smaller layer heights result in higher resolution prints, but they also increase print time and require more precise calibration.

### Material Extrusion #

### Material Extrusion

Material extrusion is a 3D printing technology that involves melting and… #

FDM and FFF are examples of material extrusion technologies.

### PLA (Polylactic Acid) #

### PLA (Polylactic Acid)

PLA is a biodegradable thermoplastic material made from renewable resourc… #

It is a popular material for 3D printing due to its ease of use, low warping, and non-toxic fumes. PLA is suitable for creating prototypes, toys, and artistic models.

### Post #

Processing

Post #

processing is the process of finishing and enhancing a 3D print after it has been printed. This can include removing support structures, sanding, painting, or applying a sealant. Post-processing is necessary to achieve a high-quality, finished product.

### Resin #

### Resin

Resin is a liquid photopolymer material used in 3D printing, particularly… #

Resin is cured by exposure to light or heat, creating a solid object. Resin is known for its high resolution and detail, making it suitable for creating dental models, jewelry, and detailed prototypes.

### Slicing #

### Slicing

Slicing is the process of converting a 3D model into machine instructions… #

This involves dividing the 3D model into layers and generating G-code instructions that specify the movements, speeds, and other parameters required to create the 3D print.

### SLA (Stereolithography) #

### SLA (Stereolithography)

SLA is a 3D printing technology that uses a laser to cure liquid resin la… #

SLA is known for its high resolution and accuracy, making it suitable for creating detailed models, dental applications, and jewelry.
