05_Week work:
This week my goal was to know the different types of scanners, printers and filaments, in order to be able to differentiate the proper use of each occasion. Depending on the project it is advisable to use one type of technology or another. High-end scanners such as the Artec Spider can scan with high quality.

Sofware:
Cura, 123DMake, Rhino, Sense, Artec Studio 11 Profesional.

Machines:
Scanner: Artec Space Spider, Artec Eva, Sense. 3D printer: Printrbot simple, ProJet CJP 460Plus

Artec Spider + Projet CJP 560Plus:

In this assigment we have seen the headquarters of 3dsystems in Costa Rica to be able to test the different type of scanner that there is in the market. For group assigment we tested the Artec spider, currently one of the most quality scanners on the market. I wanted to try scraping a product with a lot of texture, to be able to compare it with the original and check the high resolution of the scanner, and then print in 3d with one of the high quality dust printer Printer CJP 560 plus. From my perspective, to be the best scanner with one of the best printers the results were not all that good I expected. In the video you can see the process and the final results obtained..

Scanning:

In the assigment group, We use different types of scanners, to understand the characteristics of each one. We try to scan several pieces but depending on the reflective material or opacity of the part the scanner can detect it or not with higher quality. Finally we used a white coral, since it was the object that best obtained the information to be able to move to 3D printing.

Name: Artec Spider. Manufacturer: Artec. Pros: High quality scan, texture+geometry, 0.1 mm presicion. Cons: short range, small scale objects

Name: Artec Eva. Manufacturer: Artec. Pros: High quality scan, large objects. Cons: less precise compared to Spider (0.3mm), cannot scan textures

Name: Sense Scanner. Manufacturer: 3D Systems. Pros: Availability, user friendly, cheap. Cons: Low quality scan, single scan only.

Name: XBOX Kinnect Manufacturer: Microsoft. Pros: Availability, user friendly, cheap. Cons: Low quality scan, multiple image scan using KScan3D

Cura and Sense Scanner:
The software I have used for 3D impressions has been the Cure. It is a very easy to use and very predictive program. I imported the piece in format .stl to the program and then apply the parameters needed for printing. Print Parameters: Layer height: 0.1984 mm, shell thickness: 0.8 mm, enable retraction, button/top thickness: 0.4 mm, fill density: 15%, print speed: 30 mm/s, printing temperature: 200c, support type: none, platform adhesion type: none, filament diameter: 1.75 mm, flow: 100.

The printer must be at least 210 degrees to be able to insert the filament in order to be able to print. In this assigment I did several tests both scanning and printing. In the photos you can see the different results. The scanner you use in this case was:

Name: Sense Scanner. Manufacturer: 3D Systems.

Modeling and Printing:
This part of the assigment was a challenge for me, because the modeling of the piece was very complex. Take great time for the measurements and inclinations of the piece to be correct. The program I used to model in 3D has been Rhinoceros. Casa día I am getting more familiar with this program and I find many advantages when it comes to industrial design, since you can choose the exact measurements at all times, including the angles of the piece.

For printing I will need PLA filament with holder, alcohol, paper towels, pliers, blue masking tape, a flattening tool. In my experience it is very important that the bed, this well clean and do not touch much to not leave the fat of the hands. That's why it's always good to clean with alcohol the strips of masking tape to protect the bed. Layer height: 0.1984 mm, shell thickness: 0.8 mm, enable retraction, button/top thickness: 0.4 mm, fill density: 15%, print speed: 30 mm/s, printing temperature: 200c, support type: none, platform adhesion type: none, filament diameter: 1.75 mm, flow: 100.
