FABLAB PERU

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

An embedded system (also known as “embedded”, “embedded” or “integrated”) is a computing system designed to perform specific functions, and whose components are integrated on a motherboard.

Group Task: As a group task, we'll make prints with different characteristics using 3D printers. Individual Task: Design and print 3D objects. 3D scan an object (and optionally print it).

Visit to iFORNITURE Fab Lab

To develop the group project, I visited the iFORNITURE Fab Lab, located in Lima, Peru, where our friends Cristian Loayza and Evelyn Cuadrado are based. We observed various pieces of equipment, including the 3D printer, CNC router, CO2 laser cutter, and other Fab Lab equipment. When testing different materials and printers, we observed variations in the results obtained depending on the different configurations. We were able to optimize the printing time of the models, as they were printed simultaneously.

Individual assignment

Design and 3D print an object. To perform this task based on a 3D model, you can download some 3D design files, one of them is the thingiverse.com software which is very interesting and challenging for 3D printing. In this case, I chose a 3D design based on a wagon wheel, which I found very interesting.

Printing procedure using Bambu Studio

In this section, we can see the steps followed to 3D print the wagon wheel selected using the thingiverse.com software. In this case, for 3D printing, I downloaded the Bambu Studio software, taking advantage of the fact that I have a Bambu Lab A1 printer.

Printer selection

The selection of the Bambu A1 printer was then made.

Printer Features

In the setup menu, you can see the specific details of the Bambu Lab A1 printer that need to be entered, such as bed type, quality, and other information.

Import image

Next we import the image that was previously downloaded in STL format.

Laminate plate

Then in the Laminate plate option, the printing details are verified, such as line type, time, filament, among others.

Preview of laminated plate

Below you can see the laminated plate showing the corresponding heights and the codes that are generated.

Finalized print of the wheel

After setting up the printer, the finished 3D print of the wagon wheel is shown, resulting in an excellent print according to the required object.

Designing a 3D object with Solidwork software

In this section we will use 3D modeling, parts and design assemblies and simulation of object drawings for production. SOLIDWORKS 3D CAD software is a good option to take the design to the printing of objects since it facilitates the image converted to STL format to be exported to the Bambu Lab software and then printed in 3D.

Open a new drawing document in SolidWorks

The first step is to open a new drawing document in SolidWorks. In this case, we create a preliminary drawing of the object chosen as a design for a utensil such as a cup.

Plane of rotation

The next step is to create a rotation plane to generate the complete image in 3D design.

Rotated 3D image

The next step is to obtain the rotated image in 3D

Side view for race handle design

Fixing the handle

Next we set the vertex and angle parameters of the handle

Final view of the 3D designed rate

Bambulab A1 3D Printing

We started 3D printing the cup on the Bambulab A1 printer.

Final 3D print

Final sample of the 3D print of the cup.

3D Scan KIRI Engine

To perform the 3D scanning, I used an app called KIRI Engine for my smartphone, since the UNCP Fab Lab doesn't have a scanner. So I downloaded the app to my cell phone.

To scan an image, I used a Lego robot object, taking an average of 20 photos as directed by the application. I then downloaded the image in OBJ format and imported it into Bambu Lab Studio.
