Below is a screenshot of an email confirming that my submission has been shortlisted for the competition. 

Reconsider design

Example of the program Replicator with the converted sketch up as STL file.
Above is a demonstration of the model in the Replicator program. 

During the design process of creating the future milk bottle. There were a lot of complications due to the process of building the shape and the size:

• Firstly, the development of the design brief and to improve the sketch model with approximate dimensions for 3-D model prototyping 
• Secondary use “Sketchup” software to generate 3D and export STL files.

Bottle - sketch up example

Bottle - lid sketch example 

• Thirdly for the 3D Printer, using a 3D printer software known as ReplicatorG conversion. 

Example of generating and changing the Replicator G-Code generation for 3D printer.
This alters the temperature of the plastic through the nozzle and the temperature of
base. 

• Fourthly, a lot of trials, failures and error corrections (takes days or weeks) to arrive at a workable prototype. Shown below: 

 

 

Above are the failures when converting the sketch-up file and replication program into the 3D printer. For example for the handle of the bottle or bottle lid cannot print in mid air. The 3D printer can only print upwards and in layers. Thus of the problem of this makes the plastic curl and deform.  

• Next the successful prototype sample is brought into the Crit session to receive comments, suggestions and recommendations from peers and tutors.  

Miniature designs are taken to crit sessions to received
feedback on model. 

 

• Next refining the final output - accurately determining the dimension uses 'tape measure' function in Sketchup and moving the parts into correct position for 3D Printing - i.e, lining up the parts to make a composite item without printing a section in mid-air. 
• Finally assemble the parts and prove the mechanism works. 

 

 

There are the final images of the 3D design of the future milk bottle. Due to the brief it outlines that this bottle will need to be suitable for children as well as the elderly (especially with arthritis) due to having the disability to be able to grip. There is a big enough space between the handle and the bottle. The elderly can easily grip with two hands or one and the lid of the milk bottle pops open by the top edge of the handle thus making the bottle open to allow access for the milk to pour out. 

The design is not 100% completed due to the lid. The issue of the lid design is not stable enough when the whole lid comes off. There is a mechanism that needs to be able to make this functional.
