SASKIA HELINSKA

Saskia, a Fabricademy alumna, was a major inspiration for me in applying to the program. Her final project, Unflatables, left a strong impression on me with its innovative approach to inflatables in design. I truly appreciate how she explored new dimensions with this project, showing the potential of inflatables in creative fields and inspiring others to think outside the conventional boundaries. Her work exemplifies the experimental spirit of Fabricademy, making her a role model in my own journey here.

Process and workflow

In Rhino, design a compact pneumatic bending actuator by defining its length, width, height, and chamber separation for precise movement. Incorporate internal channels for airflow, ensuring smooth pneumatic control. Optimize wall thickness for flexibility while maintaining durability. Use Grasshopper for parametric adjustments, enabling easy modifications. Create tubing connection points and refine edges to prevent weak spots. By integrating these elements, the actuator achieves efficient bending motion with controlled air distribution.

3D Print Model

step 1: Design the Actuator Using Rhino software

step 2 : slicing software using ultimaker cura

In Ultimaker Cura, prepare the 3D model for printing by importing the Rhino-designed actuator and orienting it for optimal strength. Adjust layer height for resolution, infill density for flexibility, and wall thickness for durability. Enable supports if needed for overhangs and set the build plate adhesion type to prevent warping. Fine-tune print speed and temperature based on the filament used, ensuring smooth extrusion. Finally, slice the model and preview the layers before exporting the G-code for printing.

Step 3 : Choose 3D Printing Material

When selecting a 3D printing material for projects that require flexibility and elasticity, consider using thermoplastic polyurethane (TPU) filaments. TPU is a highly durable and versatile material known for its rubber-like properties, making it ideal for creating flexible, impact-resistant parts. Its elasticity allows it to bend, stretch, and compress without breaking, which is perfect for applications like wearable devices, flexible joints, or protective covers. Additionally, TPU maintains its shape and resilience over time, even under stress or repeated use, ensuring long-lasting performance in various environments.

step 4: 3D Printing

After selecting the printing material, it is time to proceed with 3D printing. The finalized STL file is loaded into the slicing software, where print settings such as layer height, infill density, and support structures are configured to ensure optimal results. Once the parameters are set, the model is sent to the 3D printer, where the material is gradually deposited layer by layer to bring the digital design to life. Careful monitoring during the printing process helps ensure accuracy, prevent errors, and achieve a high-quality final print.

Results

I'm a little disappointed with my result because it didn't turn out as I expected. The TPU created some gaps, allowing air to pass through when compressed, which affected the outcome. This issue led me to rethink my approach, and I've decided to use a mold and silicone for my next experiment to achieve a better seal and improve the overall functionality.

Vinyl Inflatable

To make inflatable I wanted to make something like paper art. you will need;

• Baking paper
• Heat transfer vinly sheet
• Iron
• Scissors
• Pencil

Steps

1. Cut the Baking paper in a square shape then fold it into a triangle

2. Use scissors to cut out shapes from your baking paper( I did a snowflake and hearts).

3. Cut 2 vinyl sheet larger than the baking paper

4. Stack the vinyl sheet, baking paper, and another vinyl sheet in that order, making sure the baking paper extends slightly beyond the vinyl in the area where you'll insert the straw.

5. Cover with a cloth and iron slowly.

6. After ironing and letting it cool slightly, peel off the clear sheet from both sides of the vinyl to make it easier for air to be blown in.

7. Insert a straw and blow air into it. Observe how it bends.

Results

It's the outcome I noted in the draft—a different shape with a longer top edge that forms a pathway for airflow to spread, making it curve slightly when air is blown into it.

I've been making leaf-shaped vinyl inflatables and enjoying the process. Experimenting with shapes and sealing techniques has been rewarding, as the inflatables take on dynamic, lifelike qualities. Small design adjustments influence their inflation and behavior, making this hands-on exploration both a learning experience and a source of new ideas.

Soft Robotic with Gelatin

My mate Magali and I experimented with soft robotics using gelatin. At first, we weren’t sure how the material would behave, but through testing, we explored its flexibility and responsiveness. Step by step, we refined our approach, learning how to control its movement and structure. It was a fascinating process that combined biomaterials with soft robotics, opening up new possibilities for innovative designs.

Process

After conducting the experiment, we had to wait 24 hours for the gelatin to fully set. This waiting time was crucial, allowing the material to stabilize and achieve the right flexibility for soft robotics. It required patience, but once ready, we could properly test its movement and responsiveness.
