As told in the planning, each of us would come up with a multiple reproduction methods for Harry. We pitched these ideas to each other and discussed which would suit the purpose of this project best. Afterwards everybody choose their favorite and best method, making sure we had a diversity of production techniques.
Sander Plaster Print
The goal of this technique is to recreate Harry as well as possible. Therefore, the existing cup will be plaster printed in several pieces. Af varnishing the inner and outer surface, these pieces will be glued together in order recreate the cracks. The holes shall be filled with separately (Ultimaker) 3D-printed parts.
Irene Paper printing
Using the technique of 3D printing paper it is possible to make a relatively inexpensive product using a 3D printer. We don’t expect this technique to be waterproof. By experimenting with lacquer or varnish we can find out the possibilities to make the cups usable for daily usage. To print the rough version of Harry it will cost €34,- euros.
Kotryna 3d printing/plastic injection molding
With this technique we could achieve a very sophisticated look for a high end product. With this design we would bring out the beauty of 3D printing by making an expressive carcass which will either support the cavities in the structure or the whole structure. This also accentuates the historical marks on the object, which is necessary because the original form is then recreated in transparent material. The latter can either be achieved by plastic injection molding (which is beneficial if this is produced in larger numbers) or by using a Objet500 Connex printer (very convenient, because the whole object can be printed out in one go). Moreover, this design would be very interesting if steel 3D printing could be achieved in very small diameters, since then the translucent material could be glass.
Jorinde Vacuum Forming
The main reason for choosing this technique is because 3d printing is too expensive for a consumer product, so the product is still not used for its purpose. The most used cup has got to be the plastic disposable cup. This cup is made with the technique thermoforming, but this is not achievable in the short amount of the we have. Therefore the simplified technique vacuum forming will be used. With vacuum forming s sheet of plastic is heated and forced against the mold by the suction of air. It is important that form is mold-releasing.
With this technique it isn’t possible to use different materials or make holes. To preserve the historic character of the cup the difference between the shards will be made visible with a difference in height. CNC milling at PMB cost 10 euros.
|Basic (existing) shape||Cracks||Holes||Speciality|
|Sander||Plaster, several separately printed parts||Through glueing the parts together||Seperately 3D-Printed||Trying to recreate Harry as well as possible|
|Irene||Paper||Different colour||Low budget|
|Jorinde||Plastic, vacuum formed as one part||height difference
between the shards
|Holes have to be filled, visable with height difference||Making an old thrown away cup into a useable and disposable product|
|Kotryna||Plastic, (partially) 3D printed (and plastic molding)||Surface texture, carcass deformations||Carcass or carcass deformations (depends on the final design)||Showcase of 3D printing possibilities and accentuating historical footprint in newly added details|
