A Dentist’s Guide to Choosing Dental LCD 3D Printers

As the world of technology rapidly progresses, dentists are not being left behind. 3D printing has evolved to the point where devices are able to accurately print out dental models, crowns, and bridges to the T.

Creating dental models the traditional way includes the time-consuming process of taking impressions of patients’ teeth using substances such as alginate or polyvinylsiloxane — which often tastes unpleasant — while waiting for the material to settle in the mouth.

After a dental impression has been created, stone is then poured into the impression to create a permanent dental mold. Waiting for the stone to dry could take anywhere from 30 minutes to an hour. This entire process is tedious and mistakes can easily be made. Even if a tiny error occurs, one would need to restart the entire process from scratch.

Resin 3D printing simplifies this process by using CAD software programs to create the perfect dental model. Now, all dentists need to do is scan the patient’s teeth, design it with dental software such as Exocad and then directly import the file into slicer software such as FormWare so that you can slice the file. After that, your dental mold is now ready to be printed out with a 3D printer! This significantly reduces the chance of mistakes and errors. To learn how to set dental supports, please click here

Let’s take a look at what dental resin 3D printers Phrozen currently offers:

Sonic 4K - For Extreme Precision & Accuracy

Precise Dental Printing

With a printing area of 6.1in, Phrozen’s Sonic 4K is best for printing out extremely precise dental parts in 4K resolution.

Dental parts such as immediate dentures, bridges, and crowns, all require precision and accuracy to ensure a perfect fit with your teeth.

As an example, Sonic 4K is capable of containing up to 28 immediate dentures per plate. As the Sonic 4K prints out 1 layer in only 1 second, these can easily be printed out within 25 minutes.

With its compact size, the Sonic 4K is also easy to store in both labs and dental clinics.

The Sonic 4K 3D Printer comes with:

  • 6.1in Printing Area
  • 5in Touch Panel
  • 35 µm XY Resolution
  • 90mm/hour Print Speed 

Sonic XL 4K - For Increased Productivity

Sonic XL 4K Full Plate of Dental Arches

Aimed at professionals, Phrozen’s Sonic XL 4K 3D printer has a 45% bigger printing space than the Sonic 4K, allowing dentists and practitioners to print out large amounts of dental 3D models faster than ever before.

As an example, the Sonic XL 4K is capable of containing up to 5 flat arches per plate while the Sonic 4K can contain only up to 2 flat arches, therefore more than doubling your productivity. The Sonic XL 4K makes it possible for users to print out a full plate of dental arches within 25 minutes.

The Sonic XL 4K is also a great choice for printing out surgical guides that help to guide dentists to accurately place dental implants in patients, or even dental splints which are placed on the surface of the teeth to protect them from damage caused by continuous clenching or grinding.

The Sonic XL 4K 3D Printer comes with:

  • 8.9in Printing Area
  • 5in Touch Panel
  • 50 µm XY Resolution
  • 90 mm/hour Print Speed

Let’s take a look at this chart:

Sonic XL 4K:
With a larger build area than the Sonic 4K, the Sonic XL 4K allows dentists to produce larger quantities of dental models in one-go, saving both time and money.

Sonic 4K:
The Sonic 4K prints dental models with extreme precision, printing out the tiniest of details that are present with 4K resolution. With its compact size, the Sonic 4K is also easy to store either at a clinic or at a lab.

Productivity VS Speed
As an example, if you choose to print dental arches flat at 100 µm layer height using both the Sonic XL 4K and the Sonic 4K, it will take roughly 25 minutes.

The Sonic XL 4K can print out 5 arches per plate at a time while the Sonic 4K can only print out 2 arches per plate. This means that the Sonic XL 4K will be able to print roughly 12 dental arches in an hour while the Sonic 4K will be able to print roughly 4.8 dental arches per hour.
