IN our lab the instructor explains the major fator to consider When designing for 3D printing,
there are some design rules that you should keep in mind to ensure successful printing.
Here we got some key tips to help you test the design rules for 3D printing
Wall thickness: Make sure that the walls of your model are thick enough to be printed.
Generally, a minimum wall thickness of 1mm is
recommended, but this can vary depending on the printer and the material used.
Overhangs: Overhangs are areas of your model that are printed without any support structures.
Generally, overhangs should be kept to a maximum angle of 45 degrees to ensure successful printing
Support structures: For areas of your model that require support during printing, you'll want to add support structures. These can be automatically generated in most 3D modeling software, or you can manually add them.
Make sure that you add enough support structures to prevent any sagging or warping of your model.
Orientation: The orientation of your model can have a big impact on print quality. Experiment with different orientations to find the best one for your model.
Keep in mind that some printers may have specific requirements for orientation.
.
Material choice: Different 3D printing materials have different properties, so it's important to choose the right material for your project. For example,
some materials may be more prone to warping or require higher printing temperatures than others. but in our lab we have used pla as material to print madel with good apealence
Test print: Before printing your final design, it's a good idea to print a test model to check for any issues. This help us to save time and materials in the long run.

It was a challenge in getting an
integrated part to move after printing it as one piece on a 3D printer.
This have been frustrating, as I likely put a lot of time and effort into designing and printing the part.
However, after some reflection, I realized that a door hinge could be printed and act like that.
This realization likely gave you a burst of energy and motivation, as I saw a potential solution to your problem.
You were likely eager to test out your idea and see if it worked, and it's possible that the satisfaction of finding a
solution to my problem helped to motivate me even further.
DESIGN PROCEDURE OF MY DESIGN OF HOLIZONTAL DOOR HINGE
Design of hinge in solidworks
Design of the base of hinge : after realising that the hinge composed with base and movable link for locking .Above pictures shows how the base of the hinge is designed.

here you can see that my hinge lock was designed with the respect of base dimension even caonsidering fitiness of the lock in base of the hinge after printing the model.

Installation of silising software
Ultimaker Cura is a free and open-source slicing software that is widely used in the
3D printing community. It allows users to prepare 3D models for printing by slicing them
into layers and generating G-code, which is a machine-readable language that
tells the 3D printer how to move and extrude the filament to create the object.
below you can find the procedure i used to install it in my pc.
Open the software and select your 3D printer from the list of available machines.
Import your 3D model into Ultimaker Cura by clicking on the "Open File" button or dragging and dropping the file into the software.
Once the model is loaded, you can adjust the print settings such as layer height, infill density,
and print speed to optimize the print quality and speed.Next, I imported the STL file into
the 3D printing software on my printer, which is a Creality Ender 3. I set the printer to use a
layer height of 0.2mm and a printing speed of 60mm/s. I also used a material called PLA, which
is a biodegradable
plastic that is easy to work with and produces high-quality prints.
When you are satisfied with the print settings,
click on the "Slice" button to generate the G-code file.With the printer
set up and ready to go, I began the printing process. The printer used a process
called fused deposition modeling (FDM) to build the hinge layer by layer. The printer
extruded the PLA filament through a hot nozzle and deposited it onto the print bed in
the exact pattern required by the model. The printer continued to build up the layers until
the entire hinge was complete.
Save the G-code file to an SD card or transfer it to your 3D printer
using a USB cable or Wi-Fi connection.
Overall, the 3D printing process was a fantastic way to create a precise
and functional hinge for my project. The ability to design and print complex shapes in
a variety of materials has opened up a whole new world of possibilities for makers and
designers alike. I hope this introduction has been informative and
inspiring for those looking to explore the exciting world of 3D printing.
3D Scanning
The first step is to download and install the Sense software from the official website.
The Sense software is available for both Windows and Mac operating systems.
You can visit the official website to download the latest version of the software.
Connect the Sense device to your computer,After installing the Sense software,
connect the Sense device to your computer using the USB cable provided with the device.
Make sure that the device is properly connected
to your computer and is turned on.
Launch the Sense software,Launch the Sense software on your computer.
The software will automatically detect
the Sense device.after sellecting type of sothing you are ging to scan a aprompt you to start scanning.
Calibrate the Sense device
Before you start scanning, you need to calibrate the Sense device.
Follow the on-screen instructions to calibrate the device.
The calibration process involves capturing images of a
calibration card that is provided with the device.
Start scanning
Once the device is calibrated, you can start scanning.
Hold the Sense device steady and move it around the object you want to scan.
The software will capture the images and create a 3D model of the object in real-time.
Refine the scan
After completing the scan, you can refine the 3D model using the editing tools
available in the Sense software. You can remove unwanted data,
fill in gaps, and smooth out rough areas to create a more accurate model.
Export the scan.
Once you are satisfied with the 3D model, you can export it in various file formats, such as OBJ, STL, and PLY.
You can then use the exported file in other 3D modeling software or 3D printing software.
That's it! These are the steps used 3D scanning technology using the Sense device and its software.
I hope this helps. below you can find the link to download the my file.
