Will the polyproplene process work ?

I have done a quick look into researching the injection process of one single piece , and if this will be strong enough and work. My findings have been informative.

To the left is the Bellini chair designed by Mario Bellini. He has made the chair using the injection molding process and the chair is a single piece, no seams no blemishes. The one difference to my idea of just using polypropylene is that the chair is a mix of both polypropylene and fiberglass. This gives added strength and durability.

From seeing this I wanted to see other mixes of materials that other designers have used.

This is the Mem chair by Kristalia. The chair is again made in injection molding and is reinforced with glass. From this description I assume its fiberglass and not just glass used. I am keen to use fiberglass to strength my own chair.

I also did come across another small piece of information.




This is the Lisboa chair designed by Jon Gaspar. Its is a single piece again that only uses polypropylene only. The process is different though using injection molding that is gas assisted. I am unsure if this makes them hollow. Either way I will be using injection molding to make a solid object.

After scrolling down I did see that the Lisboa chair is polypropylene and fiberglass.

I will now be using a mix of polypropylene and fiberglass to make my chair and using the injection molding process. 

One simple curve

 After a chat with my tutor , he recommended I look ad adding a curve from the back to the seat of the chair. I have done some drawing to look at the idea and I do like it . This means i will have to do some remodeling of the chair on rhino.

We also spoke about maybe have a different material for the chair, maybe wood or metal but something to keep in tie with the cat theme. I will do two models one as a single molded piece and the other with a different material for the legs (including fixings)

I will research to make sure that the polypropylene injection process will work by looking at other products that have done this and other materials possible for the chair.  

Something to show

After a day of sitting infront of a computer i wanted to show something for my labour. Its not rendered or anything but I have the shape and form sorted now. I used rhino to model the chair and now i will use maya to render. The model had a few dips but i sorted them out and smoothed it all out.

Presentation board ideas

I have drawn up some quick ideas to show my thoughts on photo shop. I want the idea to be that all the black is darkness and the white spots are spotlights shinning onto the images. The big image can be one of many things e.g. Chair in a white brick room, chair in a room with cat on it etc. The small ones are the chair but rotated so that the user sees it from all angles. The green is wher the name or text would go but liek i said these ideas are not set full and are very early thoughts.

Its all about angles

Now I am happy with my chair and the design I wanted to get it drawn from several angles, it helps me visualize the chair more easily and will help in later modelling stages. Any more i do ill post. I do have a habit of drawing products from one view and getting to comfortable so in future projects i want to start soon rotating the product and get a better understanding of it.


We also got told today that we need to end this project with three presentation boards (or images ready for boards) so  straight off i have come up with a idea for one board which is aimed more at the public. This is just a idea and not a definate choice of board layout yet.

More refined and to the point

Material Idea

As I stated earlier i want my chiar to be one single piece made from plastic. I am now undecided on if I want the chair to have a mate or gloss finish to it but I am certain I want it to be black. I have seen the plastic POLYPROPYLENE. This has been used in chairs before so I know how it looks and the finishs. It can be injection moulded. Below are some examples.

I did also like the plastic my hp laptop is made of but through a little bit of research i found that laptop outer cases are made of POLYPROPYLENE anyway. Which leads me to decide this will be my chosen material for my chair. Its the finish i would like and it to me looks simple and smooth .
