microscribe digitalizer

We learn how to use the microscribe digitalizer. The basic tools and a little bit of practice of how can we digitalize an obejct into the computer.

Steps

1. open rhino
2. Go to configuration
3. 3D digitalizer
4. select the microsrobe digitalizer option

There are somo basic tools that we must know as:

1. Curve with digitalize: Hold the right pedal whenever u want to digitalize. So u can scan … if its not hold it is not digitalizing
   
2. Mutliple points: every time u wan t a point u press the pedal and then release.
   
3. Planar section curve:
   -select first the planar point, then the second planar point. So u have an area to hold ur object.
   -Select a based plane. U can change the number of planes u want.
   
   
4. Interpolate points: each time u press a point it is going to join with the nearest point.

Prototyping processes

Fused deposition modeling
-Layer by layer
-Plastic filament or metal wore is unwound from a coil and supplies material to an extrusion nozzle.
-The nozzle is heated to melt the material.

Materials
-Abs polymer
-Polycarbonates
-Waxes.
Model is created in CAD. Send it to the machine.

Types of machines.
-FDM (200mc, 300mc , 400mc and 900mc)
-200 for office

Pros
Good for conceptual models,
Cost effectiveness
Cons
-Expensive


Laminated object manufacturing (LOM)

Rapid prototyping
Works with 3d models
Low cost.

-Layers of glue-backed paper from the model
-Raw materials is readily available
-Larger parts because it uses no chemicals ( no reactions involved)
-Outside model, cross-hatching removes materials.
-Before sealing models have a wood-like texture.
-Not as prevalent as SLS and SLA

How it works?
Layer fabrication with sheets being adhered to subtract with the heated roller.
Works with paper layers!
Models should be sealed with a paint or lacquer to block moisture ingress.
Strong as plastic or metal.
The paper is glue with heat. ( sinterizado)

Open hardware
Social movement, people interest on techonology created new devices byt the combination of pieces from other different companies.

Rep rap

Materials.
Thermoplastic
Ceramic
Icing sugar
Silicone
Woods
Chocolate

Its like a home printer…
Cheaper than an industrial machine.

thinking about prototypes

Thinking about prototypes is an interesting way of seeing how designers interact with their prototypes. And how this processes have been evolving along the years, they way they change from something rough to something more acurate to the "real thing". With technology and the designers experience prototyping has evolve rapidly in a good maner, before CAD printouts give the designer and the client a good idea of what their new design would looks like, but with quick prototypes as stereolithographic ones make it more real.
With this kind of prototypes the designer can actually touch and feel every single part of the prototype and intereact with it as the real product in proction, so that they can have a better idea of how things are going to be.


Is important to say that even if its a prototype, designers have been trying so hard to do it by the fast and the better pad without making so much trail and error, beacuase that makes it a waste of time and resources. "Find out what works and stop doing what doesnt works. "
There are many methods that a designer can use to make a prototypes but nowadays it is important to make them the easiest and quickest way without disaprobing the quality at all.
