Overview of 3D printing with How-to videos from Asiga

How-to: Printing a dental model, from design to print!

The video below shows you how to make 3D models from a 3D scan to the printed model. The video begins by showing the well-known intra oral scan. After scanning two complete jaws (o+b), this scan is exported to the CAD design software. In this case the software from 3Shape is used, but that can also be from another software supplier such as exocad or dentalwings.

The model is produced in the CAD design software based on the scans. These can be different models such as implant or stump models. In all cases, a hollow or full model can be used. In this example a full model is printed with “drain holes”. This is to prevent deformation due to, among other things, vacuum forces. The models are also provided with the text tag (in this case a negative one) during manufacture and then it is saved as .STL.

The STL files saved with the CAD software are opened with the Asiga Composer 3D printing software. In the Asiga Composer print software the print is prepared and nested for printing. In this case we use the auto-placement functions to easily and quickly nest it on the build platform. The supports are also used to support the models during printing. These supports are generated with the support generator and the default settings.

We close the video with the “post processing” where the printed models are chipped off the building platform. The prints are then washed in at least 2 isopropyl alcohol baths and dried with compressed air. The models from then on for another 20 minutes in the Asiga Flash curing unit or in the Otoflash G 171. In this video we used the Asiga Max 3D printer, Asiga DentaMODEL, Asiga Flash and the Otoflash G171 that are available from us.

How-to: Printen van een dentale studiemodel, van design tot print!

This video gives an easy and quick overview of the digital creation of a study model. Here we briefly discuss the CAD design software in which the model is cut out and where the plinth is placed. After placing the plinth, the models are imported into the Asiga Composer software, whereby we assume that the models are placed vertically in the Asiga Max. The models are printed with the Asiga dentaStudy model resin and this is printed on a layer thickness of 100 microns. At the end of the video we give a short overview of the removal of the models, the post cleaning of the models with the ISOPROPYL alcohol 98+% and the post curing with the Asiga Flash. If there are any questions about 3D printing for your practice or about this video, please contact us.

How to design and make a custom impression tray with Asiga 3D Printer.

The video below gives a good overview of the digital process of making an individual bite spoon. From the first stage, the video shows an intra oral scanner being used. Various scanners can be used for this, such as the Aidite Cameo scanners. After the digital print, the file is sent to the Exocad design software. In the design software, the spoon is designed based on the scanned jaw. With or without an implant, with a small or large handle, a thick or thin design, you can decide for yourself. Once the design is ready, the .STL file is exported from the design software and imported into the Asiga Composer Software.

The spoons are nested in the composer software. The spoons are often printed vertically to prevent extra support. In this video printing is done with the Asiga spoon liquid Asiga DentaTRAY.

After the Asiga DentaTRAY comes out of the printer, it must be cleaned according to protocol and the supports are removed from the trays. After that, the spoon still has to be post-hardened. This according to the protocols for the class I MDR certification. During this post curing we used the Otoflash G171 where no N2 has to be used. The Otoflash is used according to the following scheme:

2000 flashes
Turn over and wait 5 minutes (cool down)

2000 flashes
Turn over and wait 5 minutes (cool down)

2000 flashes
Turn over and wait 5 minutes (cool down)

2000 flashes


Take into account the cooling period before you use the 2000 flashes again. In total you use 8000 flashes with the otoflash.
