3D printing often results in visible layer lines or surface imperfections, making it challenging to achieve a perfectly smooth finish.

Post-processing refers to the steps taken after the 3D printing process to improve the surface quality, remove support structures, and enhance the overall appearance of the printed part.

Infill density, which refers to the amount of material used to fill the interior of a 3D printed part, plays a crucial role in determining its strength and rigidity.

Removing support structures from a 3D printed part can be challenging, especially for complex geometries, and may require specialized tools or techniques.

PLA (Polylactic Acid) is a widely used material in 3D printing due to its ease of use, low cost, and biodegradable nature.

Slicing involves dividing a 3D model into thin layers, generating instructions for the 3D printer to build the part layer by layer.

Layer height, which refers to the thickness of each layer deposited during the 3D printing process, significantly influences the accuracy and resolution of the printed part.

Many 3D printers have limited build volumes, which can restrict the size of objects that can be printed in one piece.

Nylon is a strong and durable material often used in 3D printing for functional parts that require high mechanical strength and toughness.

Extrusion involves forcing molten material through a nozzle to create a continuous filament, which is deposited layer by layer to build the 3D object.

Nozzle temperature plays a crucial role in determining the surface quality of a 3D printed part, as it affects the flow and consistency of the molten material.

Printing objects with complex geometries often requires the use of support structures to prevent overhangs from collapsing. These supports can be challenging to remove and may leave marks on the printed part.

TPU (Thermoplastic Polyurethane) is a flexible and elastic material often used in 3D printing for applications requiring flexibility, such as gaskets, seals, and wearable items.

Adhesive bonding is a common method for joining 3D printed parts together, as it provides a strong and durable bond without the need for specialized tools or techniques.
