5. 3D Scanning and printing¶
This week I worked on defining my final project idea and started to getting used to the documentation process.
3D PRINTER DESCRIPTION¶
The equipment that will be used for this week, in 3D printing, is an Ultimaker 2+, one of the equipments that are within the 3D printing area, in the Digital Fabrication Laboratory of the Continental University based in the city of Cusco.
Equipment Description.¶
Printing Technology: FFF (Fused Filament Fabrication)
Printing volume: 223x223x205 mm.
Filament Diameter: 2.85mm
Printing materials: PLA, ABS, CPE, CPE+, PC, NYLON, TPU 95th.
Nozzle diameter: 0.4mm / 0.6mm / 0.8mm.
These are some of the most common features for the use of the equipment, in addition to the software required for 3D printing.
Software used.¶
For print management, the use of the CURA software, which is the device’s own software under the ultimaker brand name, is considered further. In it you can modify some parameters
Rules for 3D printing management.¶
- Side and top faces: They help the design to have a certain shape, if they were hollow, as well as vases or completely solid.
- Filling: Parameter that allows to regulate if the piece will be completely solid or will have a certain density to save material, this helps the piece to have rigidity. Well, that will depend on the field of application.
- Support: The support is generated at points where the piece can be violated by gravity, since we are talking about molten plastic material at about 200 ° C, in short, so that the material does not go down and damage the figure is done that technique.
- Adhesion: Adhesion is a tool that can help the printed parts to hold better to the base so that it can not come off, this usually occurs in elements that occupy less space on the base, but are extensive in case of height, example: print a shaft of more than 100mm.
In order to prove the description, a test printout is made where we explain in detail the necessary considerations.
Examples.
In the case of the design, we have worked with FreeCad.
3D Scanning¶
In the case of 3D scanning, use is made of the ACADEMIA 20 equipment, a professional scanner for academic use that belongs to the CREAFORM company. We proceed with the installation of the software plus the activation of the license for use.
We start the program to control the equipment.
We proceed with the equipment calibration issue, if necessary, but here we leave it as an example.
We proceed with the help of the table for the calibration process, this thanks to the targeds.
We adhere the targeds or reference points to achieve accurate scanning of a complex object, also mention that the scanner presented some difficulties on reflective surfaces.
We scanned the object with the appropriate object-scanner separation dimensions, being: about 30 to 40 cm, also we helped us with the green LED indicator that indicates the equipment, optimal distance.
