Final Project¶
WEEK 1: From January 9 - January 15
Calendar¶
Materials Research 1¶
The research at the beginning of the project is focused on materials. It is important to define, at least with what we are going to start doing the first tests. After researching the options on the market, which are many and varied, I have made a selection in this table from a range of 6 different types.
2 of these filaments are what I believe could meet the requirements.
-
The TPU (thermoplastic polyurethane) flexible filament. - About TPU
-
Vegetable filament
The TPU (thermoplastic polyurethane) flexible filament¶
So-called thermoplastic polyurethane (TPU) is a type of elastomer that is characterised by its high flexibility and durability in processing, combining the properties of both thermoplastics and rubbers. Can stretch more than 3 times its original length. The advantage of using these filaments for 3D printing is they allow for the creation of deformable objects.
First 3D test materials:
-
Flexible filament. Width 1.75m (Acccreate). Color Brown. They call it soft PLA, but it seems that it can be a little difficult to work with. (Oullin workshop).
-
PolyFlex TPU95, flexible filament. Width 1.75. Color blue. (Oullin workshop).
Vegetable filament¶
Biosourced and compostable. High shock resistance, it can be used as a substitute for PP. A very interesting material suitable for food contact. Similar to Polypropylene PP. PP is known for its resistance to abrasion and its ability to absorb shocks, as well as relative rigidity and flexibility. Very shiny and smooth parts with a very high solidity with a slight flexibility.
First 3D test materials:
- Vegetable filament (ArianePlast) Width 1.75. White color. Bought online.
Final Cost of 1 piece Research 1¶
How to calculate the cost of the material per piece:
- Filament cost represents the cost of a 1KG spool of filament, multiplied by the weight of the print in grams (110), divided by 1000 equals print cost.
