Assignment
The goal of this week is to design and produce something with a digital fabrication process (incorporating computer-aided design and manufacturing) not covered in another assignment, documenting the requirements that your assignment meets, and including everything necessary to reproduce it. Possibilities include (but are not limited to) composites, textiles, biotechnology, robotics, folding, and cooking.
My idea of today is making a Christmas tree decorated with LEDs.
Used materials
To design my christmas tree, I used defferent materials, including:
Designing process
To design my christmas tree, I used CNC router software called Vcarve pro
Cutting with cnc router
Fiberglass preparation
A fiberglass is a form of fiber-reinforced plastic where glass fiber is the reinforced plastic. This is the reason perhaps why fiberglass is also known as glass reinforced plastic or glass fiber reinforced plastic. The glass fiber is usually flattened into a sheet, randomly arranged or woven into a fabric. According to the use of the fiberglass, the glass fibers can be made of different types of glass.
Fiberglass is lightweight, strong and less brittle. The best part of fiberglass is its ability to get molded into various complex shapes. This pretty much explains why fiberglass is widely used in bathtubs, boats, aircraft, roofing, and other applications.
I cutted two small pieces of 100 cm X 50 cm. Afterward, I created chapes of christmas tree from fiberglass.
Preparetion of Resin And Hardener
Epoxy resin comes in two parts: a resin and a hardener. Mixing the resin and hardener together prompts a chemical reaction between the two, transforming them from a liquid into a solid. Measuring accurately and mixing thoroughly is essential to making sure your epoxy resin cures properly.
There are 3 simple steps when measuring and mixing epoxy resin to ensure a perfect pour:
- MDF
- Determine how much epoxy resin you'll need
- Accurately measure both resin and hardener
- Mix thoroughly for 3 minutes, scraping the sides and bottom as you stir
Decoration
To decorate my Christmas tree, I decided to use LED strip composed by the white SMD LEDs and to control LED, I used Attiny45 microcontroller made during the electronic design assignment. more details.
