The Raydent Studio 3D printer is a well-designed and quite small unit. I’ve positioned it inside a cupboard that’s only 30 centimetres deep. When I’m not using it, I just close the cupboard door and everything is out of the way.
What’s good about it
I mainly use the printer to create study models and temporary crowns. The resin has a very high strength of about 90 megapascals so it’s strong enough to withstand normal occlusal forces. The temporary is strong enough to be left in place for several months if required.
The printer comes with a suite of software, the most important being Designer and Studio. I collect the scan data and import it into Designer. Using this program, I can modify the model in multiple ways. When I’m happy with the end product, I export it to Studio and it will design the support structure. Then I run the program and the model prints out in about 30 minutes. It’s possible to print four models at a time but that takes longer as more information requires more processing.
I’m planning to expand its use to make inlays and onlays. The resin strength is quite high and I believe it could effectively replace composite material. I also use it to make custom-made trays I use to take an impression for dentures.
What’s not so good
The resin for the printer only comes in A2 colour. Hopefully, they will expand the colour range in the future. The printing table is a bit small. There are times when it can be a struggle to fit a model onto it.
