Group Work Assignment Reflection
Safety Issues with Silicone
Skin and Eye Irritation: Silicone can cause irritation if it comes into contact with the skin or eyes. It's important to wear protective gloves and safety goggles. Fume Inhalation: Some silicone products, especially those that cure using acetic acid, release fumes that can be irritating or harmful if inhaled. Use these products in a well-ventilated area. Fire Risk: Although silicone itself is generally non-flammable, the fumes can be hazardous near open flames or high heat sources. Chemical Sensitivity: Some individuals may have allergic reactions or sensitivities to the chemicals in silicone products.
Preventative Measures
Wear Protective Gear — Always wear gloves and goggles. Consider using an exhaust fan or working outdoors. Avoid Sensitive Areas — Prevent silicone from contacting eyes, mouth, and other sensitive body parts. Proper Storage — Store in a cool, dry place away from direct sunlight. Keep containers sealed. Follow Instructions — Read and follow the manufacturer's application and curing time instructions. Safe Disposal — Dispose of excess silicone according to local regulations.
Safety Issues with AB Glue
Preventative Measures
Wear appropriate PPE (gloves, goggles, mask) Work in a well-ventilated area Keep glue away from heat and open flames Follow manufacturer's instructions for safe use and disposal Store in a cool, dry place with containers tightly closed
Individual Assignments
Design a mold around the process you'll be using, produce it with a smooth surface finish that does not show the production process toolpath, and use it to cast parts.
Design and 3D printing the module
I choose fushion 360 to design the module,and then use Bambu Studio to print the module.
Mold Making and Casting
I use the cardboard and the the axis of 3D print filament as material of mold， use the hotglue gun to glue the them together.
Mix the two materials together, and then pour the mixture into the mold.After that remember to remove the bubbles in the mold by using tooth pick or something sharp and thin. Place the mold for 24 hours to cure.
