Features of DLP (Digital Light Processing) 3D printers

DLP is one of the resin printing methods, which use a liquid resin that hardens under ultraviolet light. The other resin printing methods are SLA and LCD; to learn more about them, see the guide below.

Features of resin 3D printers

What makes DLP different

You may have heard the name DLP when buying a projector. Like a projector, DLP shines light only on the parts to be printed to build the object. A DLP printer exposes a whole layer at once, so it prints faster than an SLA printer. The focus can be adjusted, so the UV light can be both precise and intense. However, as the build area gets larger, the resolution of the projector drops, so DLP is not suited to large objects.

The table below compares the features of the three resin printing methods.

	Advantages	Disadvantages
DLP	Fast printing UV intensity and resolution can be adjusted, allowing accurate and strong prints	Hard to print large parts with high accuracy
SLA	Very high accuracy	Longer print times
LCD	Low-cost printers Fast printing	Exposure time per layer is fixed regardless of the part size, so print time is hard to shorten
