Blender is a popular open-source 3D modeling software known for its capabilities in creating organic and freeform shapes, making it suitable for designing objects with complex geometries.

STL (STereoLithography) is the most commonly used file format for 3D printing. It represents a 3D object as a series of triangles, which can be easily interpreted by 3D printers.

Overhang Minimization is a design principle that aims to reduce the need for support material by designing the object in a way that minimizes the presence of overhanging features.

Slicing is the process of dividing a 3D model into thin layers, typically in the Z-axis, to prepare it for 3D printing. This allows the printer to build the object layer by layer.

Material cost is generally not a direct consideration during the design phase for 3D printing. The focus is primarily on optimizing the design for printability and functionality.

Print Orientation refers to the angle and position at which a 3D model is placed on the print bed. It affects factors such as print time, support material requirements, and the overall quality of the printed object.

Hollowing is a design technique used to reduce the amount of material required for printing an object. It involves creating a hollow interior with a thin shell and an infill pattern, which helps save material and reduce print time.

Support structures are added to 3D prints to provide temporary support to overhanging features or complex geometries that cannot be printed without additional support.

Wood is not a common material used in 3D printing. PLA, ABS, and PETG are widely used thermoplastic materials for 3D printing due to their ease of use, affordability, and diverse applications.

Layer Height refers to the thickness of each layer in a 3D printed object. It directly affects the resolution and detail level of the printed object.

Infill Optimization is the process of strategically distributing infill material within a 3D model to achieve the desired balance between strength and weight. It helps reduce material usage and print time while maintaining structural integrity.

Rafts are used in 3D printing to improve the adhesion of the first layer of the print to the print bed. They provide a larger surface area for the first layer to adhere to, reducing the risk of warping or lifting.

Computer Numerical Control (CNC) is a subtractive manufacturing process, not a 3D printing technology. Fused Deposition Modeling (FDM), Selective Laser Sintering (SLS), and Stereolithography (SLA) are common 3D printing technologies.

Support Removal is the process of removing the temporary support structures added to a 3D printed object during the printing process. It involves carefully detaching the support material without damaging the printed object.

Modular Design is a design principle that involves breaking down an object into smaller, independent modules or components. This allows for easier assembly, disassembly, and maintenance of the printed object.
