Download & Install Sintratec Central
With the help of Sintratec Central you can manage your print jobs. You can download, install and get to learn the Sintratec Central even before receiving your Sintratec machine.
Please read the following software manual before you start with your first print.
Especially note the positioning tips and parameter explanations for best printing results.
The toolbar is used to import/export 3D print files/jobs and to get help.
Green bar indicates active tab.
Tab “1. Place”
In the first tab you can load 3D print files into Sintratec Central and arrange them in the print volume (position, position, rotate, and scale). Before being able to position the 3D files you need to load them into Sintratec Central. Open Sintratec Central and either click File > Add STL file or Drag & Drop the 3D files into the main user area. As soon as the first 3D files is loaded into the software the main user area changes and the build volume with its boundaries pops up.
You can either use your mouse to view the build volume or you can use the arrows in the top left corner to change the view of the build volume to a side view or a top view. If you use your mouse, you can rotate the view by holding the right button, pan by holding the middle button and zoom in/out by using the mouse wheel. The “Front” label always indicates the front side of the build volume, i.e. the front side of the printer.
Place STL Files
There are three main positioning operations which can be applied to each 3D file; translation, rotation and scaling.
You can translate a 3D file in all three dimensions either manually with your mouse or by entering the values directly in the according fields. To translate the 3D file manually you can click and hold the left mouse button on the 3D file and move the mouse in the X or Y dimension. If you press and hold SHIFT while manually translating the 3D file, the speed of the movement is reduced allowing to position the 3D file more accurately.
You can enter values in the translation fields to translate the 3D file more accurately.
You additionally can press and hold the X, Y or Z key on your keyboard while moving your mouse to restrict translation in the according dimension.
You can rotate a 3D file in all three dimensions by entering the values directly into the according fields.
You can scale a 3D file in all three dimensions with the aspect ratio either locked or unlocked.
Best Position Practice
Tab “2. Parameters”
In the second tab you can set the parameters and prepare the 3D print file(s) for printing (i.e. the 3D print file(s) get sliced into individual print layers). You can choose between the different Sintratec powders.
Select the powder you’re using and the quality you want.
Choose show preview to see the slicing and the individual layers in a “preview” tab.
Tab “3. Powder”
In the third tab you can control the left and right platform and the coater. You can set the distances the platforms will travel when controlled and apply powder layers of custom height.
Tab “4. Print”
In the fourth tab you can control the printing process.
Software During Printing Process
This section explains the Software during the printing process. Please read “Printing” to learn more about the printing process.
When you start the printing process, the print file will be transferred to your Sintratec printer.
After the print file is transferred, the printer will start/continue heating up. Heat-up your printer by pressing the “Heat Up” button. Heating-up usually takes about 1-2 hours. The get the best quality 3D parts the printer needs to have a homogeneous temperature distribution inside which takes time. You can skip the heating up with “Skip Heat Up”. We don’t recommend to skip the heating up.
When your Sintratec printer is successfully heated up, the printer will prepare the powder bed. You can also skip this step by clicking “Force start scanning”. We don’t recommend to skip the powder preparation.
The print will now start. You can follow the printing process. If you like to end the print early you can click on “Skip to cooldown”.
Target Size and Orientation
Once you have found the perfect digital scaling for your Sintratec printer, it is good practice to write it down as a backup. Even though the machine stores the values, in unforeseen cases they might get lost.
