backlight from a UV lamp. After each layer is cured, the lamp pauses to operate. During the
pause, the layer solidifies and the platform rises and lowers itself so the resin is equally
distributed in the vat. The printer is equipped with an LCD screen which is responsible for
projecting successive layers and masking the UV light. Thanks to that, the resin that is outside
the image of a layer is not cured and can be used to print the rest of the model. The printer
allows users to print multiple parts at the same time without affecting the accuracy and printing
speed. Once the printing process is finished, the model has to be post-processed in two steps.
The first step involves cleaning the print from residues of uncured resin in a liquid detergent,
whereas the second step involves additional UV curing so that the object acquires its intended
properties.
Everything begins with preparing a model. The work on the project can start in any
program which creates 3D models and generates .stl, .obj files. These are the standard file
formats supported by most types of modeling software - the model is saved as a set of
three-dimensional triangles (triangle mesh). The next step is to open the .stl file (or .obj、.nmk
files) in NovaMaker - the program created specifically for Nova3D devices. NovaMaker
prepares the model by slicing it into individual layers and saving it as a .cws file. NovaMaker
also allows you to choose the material type to be used for the model and to adjust the necessary
print settings, such as layer thickness, layer exposure time, exposure off time or how many
support structures should be generated. The file is then ready to be printed.
To start the printing process, turn on the printer, prepare the material which corresponds
with the one you have chosen in NovaMaker and carefully fill up the vat with an appropriate
amount of liquid resin. While working with the Nova3D BENE4, you can start, stop and pause
the printing process in NovaMaker. Once your file is prepared, you can transfer it from
NovaMaker to the printer’s storage in two ways. You can either save the file on a USB flash
drive and plug it into the port at the back of the device or transfer the file from NovaMaker
over Wi-Fi / Ethernet cable. In addition, NovaMaker allows you to add several printers to the
panel and create a network of devices. This solution makes it possible to produce 3D models in
a small series and manage the whole process from the screen of your computer. Each printer
