Resin Vs FDM

Resin printing and FDM (Fused Deposition Modeling) printing are two popular 3D printing technologies that differ in their processes, materials used, and resulting print quality. Here are the key differences between resin printing and FDM printing:

Resin printing: Resin prints require post-processing to remove excess resin and to cure the object fully. This usually involves washing the print in a solvent, such as isopropyl alcohol, and then curing it under UV light to ensure its final hardness.

Printing Process:

Resin Printing: Resin printing, also known as stereolithography (SLA) or digital light processing (DLP), uses a liquid resin that hardens when exposed to a specific wavelength of light (usually ultraviolet). The printer creates objects layer by layer by selectively curing the resin using a light source.

Materials:

Resin Printing: Resin printing utilizes photopolymer resins, which come in various formulations such as standard, flexible, tough, or castable resins. These resins can produce highly detailed and smooth prints with excellent surface finish.

Print Quality:

Resin Printing: Resin printers generally provide higher print resolution and smoother surface finishes due to their ability to produce fine details. They can achieve intricate geometries and intricate designs with sharp edges and thin walls.

Printing Speed:

Resin Printing: Resin printing is typically slower compared to FDM printing. The curing process for each layer can take several seconds to a few minutes, depending on the printer and the height of the layer.
