Group Assignment Contribution

In this Week, I have Contributed in the understanding characteristics of My 3D Printer

Characteristics of my 3D Printer

In our Lab we have two Printers one is from Creality and another one is from Flash Forge

About FlashForge Creator 3 Pro

The FlashForge Creator 3 Pro is a professional IDEX (Independent Dual Extruder) 3D printer, allowing dual-material and multi-color printing. It has a 300°C high-temperature extruder, enabling compatibility with a wide range of filaments like PLA, ABS, PETG, PC, and Nylon. The heated flexible build plate improves adhesion and makes print removal easy. With an enclosed chamber, it maintains stable temperatures for better print quality. The active leveling system ensures precise calibration. It features Wi-Fi, USB, and Ethernet connectivity for remote operation. It cost comes around Rs. 2L

Designing the 3D Printer File

For Designing the File we are going to Fusion 360 which is a software for 3D moels and can able to render and simulate in it

Initially what we are gonna do is to draft a 2D sketch of a hollow pipe by drawing a single line with a 10mm lenght and 10mm height

Next we are gonna draw the profile of the hollow pipe by drawing a circle on the opposite plane

Then we will use the Sweep Protrusion to extrude the pipe to a height of 100mm

Then repeat this process for the all 4 Directions

Afterwards we can make it more shine by adding colors

Why can't we design the 3D printer file subractively?

Its because the Moulding can be done for the straight and some certain angles can be moulded but here the pipes are internally connected so that it can't be done by any moulds

Initially we need to choose the 3D printer to match the bed size, we have chosen Creality Smart CR-10 Pro

Setting Configuration & Support Selection

Machine Setup

We have to setup the proper bed Temperature in our Machine

1. For the Material what we are using is PLA
2. So the Bed temperature we would be set around will be around 210°C to 220°C
3. And the Bed temperature will be around 60°C
4. So this is the setup we have to get it done in our machine

In the below image we can see the initial stage of part printing

3D Scanning

As in our lab we don't have any 3D Scanner, so we have to use the app called KIRI Engine

Model that I planned to scan is my day to day friend

About KIRI Engine

KIRI Engine is a 3D scanner app that can be downloaded from the Google Play Store. This app allows users to scan objects in 3D using their smartphone camera. The app can be used to scan small objects, but it is not suitable for large objects. The app is available for both Android and iOS devices.

Download KIRI Engine from Google Play Store

For the 3D scanning we are gonna use the app known as KIRI engine

Here we need to give around as a 50 Images as input then It would blend all the images then it will give us a 3D model and it can be downloaded

Initially the model was not the best model so we have to refine it by using the Refine feature of the app. So I need to do the same Process again

After Further Refination I got this model

Learning Summary

• Learned how to design a 3D object using Fusion 360.
• Understood how to export a 3D model as an STL file.
• Learned how to prepare a 3D model for 3D printing using Slicer.
• Successfully printed a 3D model using a 3D printer.
