This can make it faster than SLA for certain types of prints. The resolution of the projector determines the precision, and high-resolution projectors can achieve incredible detail. DLP is often used in applications requiring both speed and precision, such as manufacturing small electronic components.

• Two-Photon Polymerization (2PP): Now, this is where things get really interesting. 2PP uses a highly focused laser to cure resin at a specific point in space. By controlling the laser with extreme precision, it's possible to create structures with features smaller than the wavelength of light. This allows for the creation of incredibly tiny and detailed objects, such as microfluidic devices and metamaterials. 2PP is at the cutting edge of 3D printing technology and is pushing the boundaries of what's possible.

• Material Jetting: Material jetting involves depositing tiny droplets of material onto a build platform, similar to how an inkjet printer works. However, instead of ink, these printers use specialized materials like polymers or metals. The precision comes from the ability to control the size and placement of the droplets. Material jetting can be used to create multi-material objects with varying properties, making it suitable for applications like creating realistic prototypes and medical models.

• Micro-stereolithography (Micro-SLA): As the name suggests, Micro-SLA is a miniaturized version of SLA. It uses a high-resolution light source and optics to cure resin with extreme precision. This technology is capable of creating objects with features as small as a few micrometers, making it ideal for microfabrication applications. Micro-SLA is used in the production of micro sensors, micro actuators, and other micro scale devices.
