3D dental printers: technology comparison and explanations
If you are interested in buying a 3D printer for your dental laboratory but are not familiar with the technical processes, you may quickly feel overwhelmed. For example, how does an LED UV printer differ from an LCD printer or a 4K DLP printer? What is additive manufacturing all about? We help you to shed light on the subject with a 3D dental printer technology comparison. We endeavour to provide explanations that are easy to understand. However, we actually limit ourselves to 3D printers for the dental sector. Otherwise this text would get out of hand.
3D dental printer technology comparison: SLA or DLP?
3D printers basically work according to the principle of additive manufacturing. New layers are always added to the existing ones. Imagine making a pottery bowl that you slowly build up from the bottom to the top with new rings. Dental printers commonly use two technologies that are closely related: stereolithography (SLA), which was developed back in 1984, and digital light processing (DLP), which is based on it.
The difference lies in how the resin is cured as a material layer by layer - in your tray, this would be the task of the burner. With SLA, a laser is used, which can work with a layer thickness of 0.05 to 0.01mm. DLP printers used a projector that originally projected light onto alignable mirrors. These directed it to the desired location, where it hardened the layers. Nowadays, LCD or LED screens are often used instead of mirrors. These make the printers considerably cheaper. As DLP printers can also work even more finely than SLA machines, they are preferable.

Innovative precision:
MTK19 high-gloss tool
Dentona's innovative technology enables precise and high-quality results in the telescope technique. Thanks to advanced milling techniques and specially developed tools, optimum surfaces are achieved that require hardly any post-processing. One example of this is the MTK19 high-gloss tool, which, with its 16 cutting edges, leaves an excellent surface that can be easily polished to a high gloss. In addition, the MTK19 Black and Green variants have been developed to remove residues and further refine the surface using rubber polishers. Watch our video to see how the MTK19 delivers fine and precise results in action.

Mit dem 3D-Drucker sind wir nun in der Lage, aus den Abformdaten selbst ein physisches Modell herzustellen, das alle unsere Ansprüche erfüllt: zeichnungsscharf und dimensionstreu. Wir arbeiten seit Jahren mit der 3Shape-Software und mussten die gewohnten Prozesse für den Einsatz des 3D-Druckers nicht verändern. Der Anwender ist mit einem 3D-Drucker von dentona nicht auf ein System festgelegt. Die zum Drucker mitgelieferte Slicing-Software liest jede STL-Datei. Somit kann die additive Fertigung problemlos in den Prozess eingebunden werden.
3D dental printer technology comparison: Frequently asked questions (FAQ)
What does the resolution mean?
A 4K DLP printer, for example, works with a screen that has a resolution of 4K. This means that it can transmit the light for curing in particularly fine detail. You can remember a simple rule for this: The greater the resolution specification, the more precise the printing can be. This applies regardless of whether it is an LED or LCD printer.
What is a 3D printer with UV light all about?
When you read terms such as LED UV printer, you can already guess that there are models with this light source that are special. Devices that work with ultraviolet (UV) light are able to post-cure synthetic resins. The product never comes out of the printer fully cured. Post-curing eliminates this problem. In the dental laboratory, for example, this can be extremely important when creating models, as these must not be soft.
Choose a 3D printer for your dental laboratory or dental practice now and help your patients even better.
As you can see, understanding the technology is actually not difficult. DLP devices are never wrong. High resolution is also almost always a wise choice - unless you are working with very specialised, simple products. Printers with UV also generally make sense for dental laboratories. However, it really depends on the individual case - we will be happy to advise you.
