The best 3D printers are used to make everything from arts and crafts to heavy industrial parts. However, when choosing the best printer, it’s essential to know the various models and their specializations. Only then can you buy what you need. Below we’re going to compare two models that often get mistaken for one another: DLP vs LCD 3D printers. Then, we’ll explain why it makes sense that people often get confused and the crucial differences setting them apart.

KEY TAKEAWAYS:

  • Both DLP and LCD printers use a light source to cure liquid resin into a 3D object.
  • DLP printers use a powerful digital projector to cure resign, which is highly accurate and dramatically reduces print time.
  • LCD printers are more cost-efficient and use an LCD backlight to power UV laser beams.

Insider Tip

Always wear proper protective gear and use a room with good ventilation whenever operating your 3D printer.

Differences Between DLP vs LCD 3D Printers

DLP and LCD 3D printers operate similarly, creating objects using a light source to cure the liquid resin. The light source projects onto the resin vat, solidifying the material layer by layer.

It sounds wildly similar, and that’s because it is. However, these two printers differ in their light source, impacting the machine’s print quality, speed, and cost.

DLP printers use a light that comes from a digital projector. It’s a highly intense light that sits below the vat of resin, and as it flashes, it cures layers of resin.

LCD printers are a much newer technology than DLPs. Here, an LCD backlight is used to project a handful of UV lasers which can cure selective parts of the resin to create an object.

If you finish this and want to know more about the various 3D printer types, we have more great articles comparing FFF vs FDM printers. And if you’re curious to keep learning about resin-based devices, we have one comparing DLP vs SLA printers.

Precision

If you compare a high-end model of either printer type, you’ll achieve better accuracy with a DLP device. LCD technology is less precise than DLP lighting. However, DLP printers tend to be more geared toward professionals and are expensive. Therefore, LCD remains an excellent option for hobbyists looking for a printer that delivers good quality.

Print Time

Both print models are faster than FDM printers. However, DLP lighting is known to be some of the fastest 3D print technology available. Digital light processing uses an incredibly powerful projector that can format an entire layer in a fraction of the time it takes for an LCD printer to accomplish the same thing.

Warning

The resin used in DLP and LCD printing can harm human skin. Make sure to use proper protective gear while operating.

Cost

The greatest advantage of LCD printers over DLPs is the cost. On average, LCD 3D printing technology ranges from $200-$2,000. On the other hand, DLP’s begin at around $500, and the professional models start at $2,000-$3,000. However, the most expensive DLP printers can reach upwards of $500,000.

STAT: Resin for 3D printers costs about $50 per liter. (source)

DLP vs LCS 3D Printer FAQs

Is a 4K LCD printer better than a 2K LCD printer?

The higher LCD resolution results in excellent accuracy and lower print times.

What is an SLA?

SLA printers are a separate type of resin-based 3D printer. However, they use a UV laser beam that can only cure specific parts of a layer for a 3D model instead of curing an entire layer simultaneously, like DLP and LCD.

What is filament-based printing?

Filament-based printing remains the most common form of 3D printing. It melts and extrudes a plastic material into layers to format 3D objects.
