What does DLP stand for?
DLP stands for Digital Light Processing
How does Digital Light Processing work?
When an object is ready to print, the build platform descends into the resin filled tank. A light projector underneath the tank projects a UV light and cures the first layer to the build platform. The UV light energy cures the resin to the build platform due to the chemical reaction. The build platform then slightly raises and comes back down to cure the next layer. This process is repeated until the entire object is printed. The printed device needs to be washed so the left-over resin doesn’t distort the object followed by a final cure so the mechanical properties are locked in. The supports should be removed after the final curing to avoid any distortions.

Does Force Feedback impact accuracy and curing?
The force Feedback is a feature which accelerates the device function/device performance. The function has no impact on accuracy of the printing process.

What is the size of the build platform?
The 3Demax build platform size is 5.12 x 2.95 x 3.54 inches.
What is Force-Feedback?
The “Force-Feedback” is an option that accelerates the printing process. Using a highly sensitive load cell, the “Force Feedback” program controls the removal process of the printed piece after curing. It monitors and measures the force of each layer when being printed and adjust it during the printing process allowing it for a faster printing speed.
What impacts printing speed of the printer?
The layer thickness and device’s height will impact printing speeds
How does orientation of the product impact print times?
An object that is flat on the build platform takes less time to print since there are less layers to print. An object that is angled on the build platform takes longer to print since there are more layers to print; however, more objects can be added to the build platform.
What is the lifespan of the resin reservoir tank?
The resin reservoir can last for approximately 300 printing cycles.
How much material does the reservoir tank take?
The material reservoir can store up to 40% of the filling level.
What are supports?
Supports are structures that are added in the Netfabb slicing software that help the device being printed remain stable during the printing process. The supports can be automatically or manually added. The supports can be easily snapped off and finished after curing.
What accessories are available with the DMG 3D digital printing solution?
These are the standard accessories that are part of the DMG 3D Digital Solution.
How is the printer and the accessories cleaned?
The parts of the printer that can be cleaned such as the build platform can be done with alcohol to wipe any resin that might have dripped. The bottom of the reservoir tank can be cleaned with the silicone scraper and window cleaning solution such as Windex.
How does the RFID technology work?
Both the 3Demax printer and the LuxaPrint resins are equipped with RFID (Radio Frequency Identification) technology. The 3Demax printers has a RFID reader and each resin will have its own programmed RFID chip. The bottle of resin is placed by the printer RFID reader which reads the information from the bottle and writes it to the resin reservoir tank. It minimizes errors and ensures reliable automatic identification of material for each print job.
How do I identify the material to be used?
The LuxaPrint material for each print job is selected at the software level when preparing the job in Netfabb, with the resin bottle using RFID technology and is identified by the printer.
What is the nesting and slicing software used?
The nesting and slicing software used is Netfabb by Autodesk.
Can custom supports be added?
Yes, custom supports can be added to a device in Netfabb.
How often should the 3Demax be calibrated?
The calibration of the 3Demax is a quick and easy process that needs to be performed weekly.
How many models can you print?
You can print 10 models vertically. You can print 5 models horizontally.
How long does it take to print models?
10 models vertically can be printed in approximately 90 minutes.
5 models horizontally can be printed in approximately 27 minutes.
Is the DMG 3D Digital Printing Solution a closed or open system?
The DMG 3D Digital Printing Solution is an open system. Third party resins can be added to the solution; however, they are not considered validated.
Is there installation/setup available?
There is an option of a virtual or in-person installation (travel costs will apply). The installation process is not difficult, and it takes half a day to complete. In preparation for the installation, a checklist will be sent to the customer. A Technical Specialist is available for support.
