3D Scanning and Printing

This week we focus on the procedures for using a 3D Scanner and printing tests of objects with different characteristics.

the assignment was:

group assignment: test the design rules for your 3D printer(s)

individual assignment: design and 3D print an object (small, few cm3, limited by printer time) that could not be made subtractively. 3D scan an object (and optionally print it).

Group assignment

To perform this group assignment, we printed on different locations and 3D printers in a distributed way, and then we could evidence and compare the results.

By testing different materials and printers we can notice that there is variation in the results given by the different configurations.

We were able to optimize the printing time of the models since they were printed at the same time.

You can see the complete documentation on the group's web page

Individual assignment

Design and 3D print an object

For this assignment find an interesting 3d model in order to understand its complexity in design and the feasibility of its printing. I downloaded a file from thingiverse.com that I found interesting and challenging for my first steps in 3D printing.

Printing procedure

In this section we can see all the steps performed to print the selected object

Designing a flower pot

We will design a small flower pot in Rhinoceros

I will start from an octagon inscribed in a circumference of diameter 60 mm.

We use the array tool to multiply the octagons x 4.

We use the loft tool to create the perimeter surfaces.

Result of creating the perimeter surface.

We make scale modifications in the XY plane.

We make modifications by rotating in the XY plane.

We generate a surface for the base from the octagon.

We generate an offset on the 1.5 mm thick surface.

Final result of the pot with a thickness of 1.5mm.

final render of the flowerpot.

Printing the flowerpot

We set up the printing using Cura Ultimaker.

In UltimakerCura we import the .stl file.

We configure the filling density at 20% in standard quality.

we apply slice

The printing time will be 2 hours 3 minutes, 16gr. and 5.34m. PLA filament.

We preview the print.

We export the G code to print.

We start printing using the Ender 3-V2 printer

3D Scan

For the development of this activity I visited OCIDE (Central Office of Innovation, Development and Entrepreneurship) of the Federico Villarreal University, this is a state university.

They have a desktop 3D scanner EINSCAN SE / SP V2, this scanner can be used easily, the learning curve for its use is very short.

3D scanner setup

The first step to scan an object is to calibrate the equipment, we use the calibration screen.
