3d print a small personalized cube
- Software used: 123D Design for 3D model designing, Netfabb Basic and Cura
- 3D printer: Ultimaker2
1.Designing the 3D model
- added a BOX primitive to the stage
- insert a CYLINDER primitive, set its radius and place it on the top of the cube
- select Extrude tool from the toolbar (Construct option) and apply it to the top face of the cylinder.
- an arrow appears and I triggered the arrow through the Box content in order to create a hole in the box.
- resize your box by selecting it and using the Scale tool. I made quite small to print it faster with the 3D printer.
2. Exporting the 3D model
- to export it, we click on « Autodesk 123D design » logo, a menu appeared and selected Export as 3D -> STL .
3. Analyzing the model
This is an important step as we need to check before printing if our model is fully closed and orientable, thus when printing the 3d printer will not print something wrongly.
- opened Netfabb Basic and open the .stl file saved previously
- Selected option Extras -> New analysis -> Standard analysis in the main menu.
- A table appeared on the right side with the features of my model. I needed to ensure that it appears – Surface is closed: YES and Surface is orientable: YES.
- closed Netfabb without any save made.
4. Preparing the model for print
- opened Cura and load the STL file.
- on the left side, added the printing options (*these options are for printing with low-detail in order to achieve a fast and efficient time of 3D printing and less use of material):
- Layer Height: 0.2 mm
- Shell thickness: 0.8 mm
- Retraction: enabled
- Bottom/Top thickness: 0.6 mm
- Fill density: 20%
- save it as a STL file and also export it as a a GCode file by using the main menu: File -> save GCode
5. Printing the 3D model
- the STL file needs to be added to a SD card.
- added this SD card to the Ultimaker 3D printer and found the file to print
- remove the material left from last time
- used the main menu of the printer – Material -> Change (there will be some waiting time for the printhead to heat) -> Remove material (select Ready)
- insert new material
- took a new spool of filament from the FabLab resources and added it behind the 3D printer instead of the old material
- added the filament at the dedicated place by pushing it inside the tube and stopped when it got in the tube.
- the machine detected the material and after loading it, we needed to select the type of material used – we selected PLA.
- after setting up the material, we got back to choosing the file and start printing
- when starting printing, the printer will display how long it is going to take.
Final note: we had to eagerly check in the beginning if the printing is going right by observing the process.
