3D - Debrecen is used for making 3D objects from PLA plastic. This guide explains how to print a 3D object from unpacking the box, until printing. It shows how to print a Stanford Bunny (Stanford_Bunny_sample.stl downloadable file), shown on Figure 1. This bunny is often used for stress testing 3D printers.
These are the 3 basics you need to use your 3D - Debrecen printer (Figure 2).
Here are the necessary prerequisites:
Optionally you can have a 3D designer software to create your own 3D objects. I advise FreeCAD as a free CAD designing software.
Setting up the 3D - Debrecen printer
Step 1 - Setting up the hardware
The 3D - Debrecen printer comes to you fully assembled. All you need to do is to
Step 2 - Installing the 3D - Debrecen Printer Software
Step 3 - Loading filament
The PLA filament is essential for 3D printing. It has the same function as the printer ink in a conventional printer. The melted filament is pushed through the extruder head to build up the printed object layer by layer.
How 3D printing happens
3D printing is composed of 3 steps. First, we have to design an object by using a designer a software. After that we have to slice our object to thin layers the printer can create by using a slicer program. This process creates a so called G-code, which the printer can understand. And third, we will have to process this G-code by using the 3D - Debrecen Printer Software to print our object.
Printing a Stanford Bunny
Step 4 - Download a sample file
Usually, design files can be easily recognized from their .stl format. If you don't want to design your own
object by using a CAD-software, you can download premade designs from different websites. The bunny's design can be found here:
Step 5 - Create a G-code file for printing
To get your G-code, you will need to use MakerBot Desktop. We are using MakerBot Desktop 3.9.0. in our tutorial. To download the latest version, please visit this site: http://www.makerbot.com/desktop
Once you have installed MakerBot Desktop, it is ready for creating G-code for multiple printer types. The 3D - Debrecen Printer uses the standard .gcode format, which is also used by MakerBot Replicator Dual.
You will have to change the default device type to Replicator(Dual). To do this, open the Devices menu on the top menubar, go to the 'Select Type of Device' item, and choose Replicator(Dual) from the list (Figure 9).
As a result, the MakerBot's Prepare tab (shown on the image above) is refitted to the size of the printer. 3D - Debrecen Printers use roughly the same size of extruder bed so this option is perfect to see the preview of your bunny.
It is time to configure printer settings. For printing, we won't use any support or raft under the bunny. The heatbed temperature should be 60 and the extruder head should be 250 degrees celsius. The printed material should be PLA. We can set these by clicking on the 'SETTINGS' menu, (Figure 10) and configuring the following options (Figure 11). Please be aware that the right extruder head of the Replicator (Dual) qualifies as the extruder head of the 3D - Debrecen printer.
We will now have to open 'Stanford_Bunny_sample.stl' in the MakerBot Desktop software, which you will find in your Downloads folder.
To do so, you can either drag and drop your design file to MakerBot's Prepare tab, or use the software's browsing capabilities to browse the downloaded bunny blueprint. (Figure 12 and 12-b).
Once you have opened 'Stanford_Bunny_sample.stl', you will see it in the Prepare tab (Figure 13). On the left side of the window, there are five buttons. The view< (selected by default and marked by an eye icon), the move (marked by four straight arrows), the rotate (marked by two curved arrows), the scale (marked by two rectangles), and the information.
To achieve the fastest and best results with the 3D - Debrecen Printer, you will have to position your bunny to the middle of the extruder bed. To do this, you will need to use the move command by selecting it's icon (Figure 13).
If your bunny is not selected by default, click on it to select it. After having your bunny selected and the move function activated, you will be able to drag your model on the extruder bed. Position it to the middle of the heatbed (Figure 14).
When your bunny is positioned, it is ready for printing. 3D - Debrecen printer works with a so called G-code, which is basically a series of printing and movement instructions. To generate the G-code, you will need to click on the 'EXPORT PRINT FILE' button on the top sidebar (Figure 15). Now you should see a classical Save as... window opened.
Since the 3D - Debrecen printer uses the .gcode format, you will have to select the 'GCode, slice only(*.gcode)' from the file formats (Figure 16). You should also browse a location for your result. Once you are done, press the 'Save' button.
A gcode generation progress bar will appear for your bunny (Figure 17). Once it is at 100%, the G-code is ready (Figure 18). In the next step we will open this 'Bunny.gcode' file with the 3D - Debrecen Printer Software and print out the bunny.
Step 6 - Printing the 'Bunny.gcode' with 3D - Debrecen
This is the easiest step. Make sure the printer is powered up and connected to the computer. The only software you will need is the 3D - Debrecen Printer Software.
The 3D - Debrecen Printer comes fully assembled and requires only one software installed to make it fully operational. The 3D - Debrecen Printer Software transforms your .gcodes to real life plastic objects. Our product has no rubber belts like most of the 3D printers on the market, so it is less vulnerable and more cost effective in the long run. The software is available for all the popular operation systems and the printer can be accessed via USB. If you have liked this tutorial, check out our other interesting and related articles below.
