ASSIGNEMENT # 3

DESIGN, MAKE, AND DOCUMENT A PRESS-FIT CONSTRUCTION KIT

PRESS FIT JOINTS DOCUMENTATION

%

The first i knew was the new cutting high format machines present in our wood local distributors. at the image the vertical bed cutting pannel machine, security, speed and precision.

On the other hand the preliminary search was referenced the work of Ricardo Torres of Fab Academy 2013. His work it's an excellent referent to get index about different union types that can be used in our excercises on this assignement.

WHAT TO DO

%

To develop a “cube” that fit between the hands could be the minimum experience possible way “press fit” fabrication technology. Concern from there the query was how to use ahead reduce wasting, by the method of using the maximum material in a bucket developed as like it.

So the things, it necessary have has to planned a design of one or more objects fiting inside a cubic box that allows to getting the objective: “press fit”. At this point the challenge include how large objects can surround at small objects ones to anothers.

Here, the “matryoshka”; traditional russian dolls, created 125 years ago, its a hollow nestable object which one the most known series knew was a 75 parts sample.Usually takes place in a first issue but are repeated in her new models equals to first one, but with different size by porportion and warrantized for be containment and at the same time be content again.

WHAT I LEARNED?

%

Interested in making with the press fit methode, a little research about it, obtain different exercises made by professionals and too by neophytes. So i got some key learnings:

1- press fit is especially used for developments in various materials laminate wood, cardboard, polycarbonate, polystyrene, and others; but can be used other various materials. Laminate wood are the most favored in our context -colombian- probably because the industrial materials has not so affordable price.

%

2- flat-rolled plan boards systems determining more “basic” results otherwise that which others that boost from the same material properties (flexibility, resilience, inhercial section ... Others).

3- The process require a minimum of required skills in hardware and software and some knowledge of vector formats exchange and having discrimination criteria of the three-dimensional drawings readable.

4- If you do not have such programs, the parameter of the multiple steps of sections and joints, even allowed to actually get accurate results. This combine with the advantage of reach a custom piece by piece detail level.

WHAT I TRIED FINALLY?

%

Attempted goal was a matryoshka collection of sucessively containers type that can have a different shapes and sections of changing. This resulted in a cubic form exercise with a simple face that contain with in two pieces for more.

Finally took a laser cutting with the below specifications
