- Page 15 3Dent™ Health and Safety Notes Risks when handling photopolymers WARNING! Risk of injury! The use of the photopolymers intended for the machine may cause risks to the health and safety of the operator or third persons. In order to ensure a safe handling of the photopolymers, the following hazard and precautionary statements must be observed.
- Page 16 Also make sure that the relevant material safety data sheets supplied with the photopolymers are observed. Those components of the photopolymers delivered by EnvisionTEC that have been classified as hazardous do not have a threshold limit value (TLV). Therefore, it is not necessary to give concrete instructions concerning the TLV.

- Page 20 Delivery Delivery The 3Dent system has been packed carefully prior to shipping, in order to practically rule out the possibility of damage to the machine if transported properly. If you notice any external damage to the packaging upon delivery, indicate this damage to the transportation company immediately and ask them to sign a damage report.
- Page 21 Construction of the 3Dent machine Construction of the 3Dent machine Different from other Rapid Prototyping systems, the 3Dent system does not use a projector but a laser unit for the curing of resins. Beside a much longer life cycle of the light source, this technique has the advantage of a minimized preparation phase for a build job and provides a more accurate processing.
- Page 22 3Dent™ Construction of the 3Dent machine Build Platform The 3Dent uses a removable granite build platform. The use of a removable platform allows for an easier cleaning and prevents remains of cured material to fall into the liquid resin. Figure 1: Granite build platform...
- Page 23 • Always use the supplied eye protection. The laser unit in the 3Dent machine consists of a rail-mounted laser head which is moved in x and y-direction by two independent control modules. Using a multi-cavity laser diode with an orthogonal mirror spinning at 20,000 rpm, the light is reflected through the spinning drum and goes through a series of optical elements, thereby focusing the light onto the surface of the photo polymer.
- Page 24 Laser beams focused through optical instruments increase the chance of eye hazard. Material Identification Module The 3Dent has a Material Identification Module (MIM) installed, that will help you monitor the material consumption at any time.

- Page 27 Consequently, the two units have to be connected through a network to be able to transfer the prepared job files to the 3Dent system. Alternatively you can use a USB stick to transfer the build job files to the machine.
- Page 28 3Dent™ Normal Operation Normal Operation Standard Procedures 7.1.1 Opening and Closing the PSA To open and close the PSA assembly, do the following: Unlock the PSA frame by lifting the locking lever up. Then lift up the PSA frame and use the latch at the top of the machine to secure it in the upper position.
- Page 29 3Dent™ Normal Operation 12. Reinstall the build platform into its frame and secure it with its brackets. 7.1.3 Cleaning the PSA After accomplishing the build job, clean the PSA using the provided squeegee. After that, check, whether any residues of cured material remain on the surface of the stretched film.
- Page 30 Normal Operation The material vat has a capacity of about 15kg. This makes the vat one of the heaviest parts of the 3Dent system that can decisively influence the machine’s balance. The positioning of the material vat as well as the initial filling will be carried out by the service technician during the machine installation.
- Page 31 Processing a Build Job The creation of a build job is carried out with the EnvisionTEC Software Suite. The application should not be installed on the Ultra 3SP machine, but on an individual computer.
- Page 32 3Dent™ Normal Operation Follow the next steps to start the job: 1. Open the 3SP Control application. 2. Make sure that there are no material residues on the PSA, build platform or platform frame. If you find any remains of cured resin, clean the build platform and PSA (see chapter Cleaning the Build Platform and Cleaning the PSA).
- Page 33 3Dent™ Normal Operation After completion of a build job, please take the following steps: 1. Open the PSA and lock it in the upper position, see chapter Opening and Closing the PSA. 2. Elevate the build platform out of the resin.
- Page 34 3Dent™ Regular Checkings Regular Checkings When your machine is delivered, it is thoroughly installed and calibrated by an authorized service technician. However, due to the high strain and pressure values the system is exposed to, the alignment of the components may be affected after a certain operating time.
- Page 35 3Dent™ Regular Checkings Take the following steps to check the PSA’s orientation. 1. Take out the material vat. 2. Clean the build platform and the PSA. 3. Start the 3SP Control application, close and lock the PSA. 4. Connect the machine with [Connect].
