Internship Project

Keychain

For the first project during the internship training, we were required to design a 3D model of a key chain using Tinkercad after an introductory session about the application with the seniors. After we have finished producing the model, the model will be inserted into Ultimaker Cura first and then printed using the Ultimaker 3D printer.

Cat Keychain

For my first design, I took the idea of making a cat shape. My first design is easy to make because I only need to combine some shapes that are already available in ThinkerCad. To make a hole on the model is also very easy because you only need to place the model and 'Hide' only.

Lego Keychain

For the second design, I took the idea of making a Lego shape by simply combining some parts or objects of the shape that are already in ThinkerCad. This second design is not difficult but requires precision in terms of size so that it does not become a different shape than the others. In addition, this model also requires 2 separate models to print 2 different colors. To print 2 separate colors it is necessary to change the 'setting' in Ultimade Cura.

Doraemon Keychain

This third design is an additional suggestion from me because on the model for the lego keychain I forgot to make a hole. I also made this Doraemon Keychain using the shapes that are available in Thinkercad. I just added different heights so that it is easy to see the color difference to create the line effect.

Zombie Keychain

I got the idea to make a zombie keychain from a game of Plant vs Zombie. This fourth design I made in Adobe illustration. For each shape, the height is different because I want to create a more realistic 3D shape on this keychain. After that I exported each shape into STL. Then in Thinkercad I import back the STL files and only change the height before combining them into 1 model

Batik Block

Bunga Raya Motive

BATIK Blok is one of the techniques to produce batik patterns. On the East Coast, it is better known as Batik Cap or Batik Terap. The initial process in the development of Block Batik involves the use of wooden block nest carvings to stamp a type of natural black dye and this early technique is known as ``Terap Hitam''. In the 1920s the use of wax in the application process was introduced. Correspondingly, blocks made of steel sheets replaced wooden blocks. Steel block patterns are neater than wooden blocks. In addition, special blocks are provided to apply wax to the fabric head, fabric cap, and fabric body.

Motifs that are often used on batik cloth are in the form of patterns of plants and local flowers such as Roses, Orchids, Cloves, Chinese Flowers, creeping roots, ferns, and geometric patterns, especially the Bamboo Shoot motif. These motifs are applied in various arrangements and layouts, such as horizontal, vertical, diagonal, patches, and brick arrangements. Most of these motifs are used on women's clothes such as 'Baju Kurung' but now they are also used on men's shirts as a way of respecting Malay works such as on Thursdays it is compulsory to wear batik shirts.

I chose the hibiscus motif because the hibiscus is the national flower. Another reason I chose hibiscus is because it has unique criteria such as interesting colors and shapes. The name hibiscus is also known throughout the country, and it is easily available throughout the country. In addition, hibiscus has also been used as a batik motif.

To print a 3D model or make a 'block batik' model I make various patterns first. I made it in adobe illustration first before choosing an interesting pattern to make into a 3D model. I made many variations of different patterns because hibiscus is an organic form whose structure is soft and different. After choosing a pattern I then export the illustration into STL. From the STL file, I then opened the file in Thinkercad. I then changed the 'Fill mode' to 'Outer Line' and the height to 10.

Honeycomb Storage Wall

Selection process

Dr Siti Azma gave us the task of choosing 4 models that she had listed to us. The four models are available in Printable to be printed as an exercise for us. We Choose the Honeycomb storage wall set. We had a little difficulty deciding which model to print because we didn't want it to take too long. We chose to print small models such as SD Holders and small containers. We printed this model using PLA Filament.

Wall Honeycomb

After the Holder and small Container are ready. We then clean it by finishing the model using sandpaper. Even if there are a few mistakes, the results of the model still look perfect and good. After that, we cleaned the building plate and proceeded to print the connecting frame or wall honeycomb on the model. We let it print overnight because the model is very large and takes quite a bit of time. After the model has been printed, we then wash some of the gaps in the model using sandpaper and the result of the model can be seen in the picture below.

Other Parts ( Shelf, hook and fastenes)

We chose additional Components after we noticed that the model seemed to lack something. We select the Shelves, hooks and fasteners that are already in the website. We changed the settings that are different from before by patching the thickness or infill in the model so that it doesn't break easily. It takes about 7 hours to print. After the model is printed we then clean the surface of the model using sandpaper. All the results of the Honeycomb model can be seen in the picture.

Hinge Project

Lego project Error

For the first project to make hinges, I made a model of the robot, but after the model was printed it failed due to the mistake of not seeing the shape or movement that would join it.

Turtle shape with Hinge

This model is based on the shape of a turtle. This model uses a hinge that is easy to make, but the process of making it takes time because it is necessary to see the effect of movement on all the hinge shapes on the legs. The results of this 3D model print are very interesting because the shell on the turtle model can make other shapes such as pen holders, phone stands and more.

Laputa Toys V1 with Hinge

This model is taken from the cartoon castle in the sky. The first process of making this model is sketching the shape of the hinge that I want to use. Then this model is made using thinkercad application. The 3D rendering process takes quite a long time because it requires precision for every movement such as hands, body, feet and more. After I was sure of the shape of my model, I then printed it using a 3D printer. And the results of the model can be seen in the picture.

New Filament - Research

CPE

CPEs (co-polyesters) are very strong and versatile materials with growing popularity in filament form for FDM 3D printing. As a printing material, CPE is highly durable, creating prints with high strength and intricate detailing. In addition, its layer adhesion is excellent with minimal warpage and shrinking.

CPE vs PLA

CPE has a much higher flexural strength than PLA
CPE is more chemically resistant and water-tight than PLA
CPE can be less prone to scratches or surface damage
CPE is more difficult to print with
CPE filament usually has fewer color options
CPE cannot be smoothed with chloroform, unlike PLA

Batik Block

For our test for filament, Dr gives us 4 filament that we can choose to print first. So we chose CPE, Because it is easy to setting in cura. The model we want to use in CPE is Batik Block. We just make it small thickness at the outline. CPE is very suitable for use because it is heat resistant, that's why we chose the block Batik model because it is heat resistant when dipped in wax.

PolyFlex

PolyFlex™ TPU95 is a thermoplastic polyurethane (TPU) based filament specifically engineered to work on most desktop 3D printers. It has a shore hardness of 95A and can stretch more than 3 times its original length. It is flexible and can make anything like clothing, shoe, phone case, watch strap, and more.

Cable tape

Our test for the second filament is to use PolyFlex filament, PolyFlex or the code for the filament is TPU95 is it a rubbery filament. TPU95 is a rubber filament that can be printed using 3D printing. Rubber 3D printing can make a variety of interesting objects, including shoes, watch straps, hair ties and more. We chose the cable tape inside the Printable because there is a 3D shape available there. After choosing the appropriate cable tape, we then continue to place the object into Cura to be set first before printing. The printout can be seen in the picture.

PolySmooth

PolyMax™ is a family of advanced 3D printing filaments produced with Polymaker's Nano-reinforcement technology, to deliver exceptional mechanical properties and printing quality. PolyMax™ PLA is an incredibly easy-to-print filament with improved mechanical properties, making it an excellent alternative to ABS.

This Filaments using for industry for making chain and more. This is because this filament is very durable and very strong.

PolyMax

PolySmooth (PVB) is a filament created by Polymaker to obtain a glossy and smooth finish when exposed to isopropyl alcohol or ethanol, but maintaining balanced mechanical properties and being easy to print.

Infographic for Makerspace

Laser Cut Machine

This is my first design for an Infographic poster. This poster is used for people who are in the Makerspace to follow the rules before using the laser cut machine. My idea is to make sure that people who see it, understand every rule that is written. I used less bright colors in this poster. I got admonitions and advice to change the poster design because this poster design does not attract attention.

Dresscode In Makerspace

The second poster is about dress code at the Makerspace. This poster uses illustration design to convey about the clothes that should be worn in the makerspace. This poster also received criticism and advice to use brighter and more attractive colors and change the shape of the design to be slightly different because the design I produced is almost the same as the existing design.

Laser Cut Machine

Second Design

For this second design I use more colors to attract the attention of the reader, besides that, I also use illustrations that are easy to understand.
