Laser Cut Lamp – Group 17

By Anya | Published: January 5, 2012

DIGITAL FABRICATION – LAMP – RIBBING

Specifications
Technique : ribbing
Material: methacrylate
Thickness : 3 mm

Design process
To articulate ribbing as an inverse technique as opposed to outward expression.
To attain fluid forms within a rigid geometry

Joinery detail
-insertion
-grooves and notches

The following were our observations:

Material
1. During the laser process, there is loss of material.
2. Loss of material varies with the speed and power used to laser.
3. The size of the sheet also affects the laser process with larger sheets prone to bulging.

Laser cutter machine
1. The slc gave us well cut, clean edged members, along with crisp engraving.
2. The blc settings were harder to control, with the engraving and cutting resulting in cracked edges and murky details despite varying speeds and power settings.

Technique
1. For a 3 mm thick sheet, a groove of 2.8 mm was the snuggest.
2. The methacrylate sheet is not flexible and is prone to cracking and splitting, more so if it is forced into a groove of a smaller size.

Milled Portrait

How to make a valcromat face?

In this exercise, it is expected to digitally design and fabricate in a Valcromat Panel and to explore the material effects that can emerge from the articulation between design, fabrication and material parameters.
With this surface as a case study we explore a specific material effect that will come out of the design strategies for surface design and/or curve pattern developed in Rhinoceros and also the definition of both the tool and machining path geometries in RhinoCAM, the composition of the material sandwich.

In order to define our work, we want to create an image, a ‘’pop art’’ portrait using the 3 colours (that will be the three layer of the valchromat panel). Our purpose was the design of this abstract portrait will come both from our own design and especially from the material effects and the capabilities of the machine. During the production process we found out that with this material (Valcromat Panel) the design follows the fabrication.

PLEXI_CUBE

PLEXI_CUBE

In this project we were working with plexiglass (methacrylate) and we focused on creating a lamp using the technique of ribbing.

We decided to explore the possible different connections between the elements of our lamp and keep the form relatively simple, having the external volume of a cube as abounding box and in its center a sphere that will provide the necessary space for the lamp. The general idea was to increase the complexity of the ribbing technique, using more than two different axises for the planar sections. In the process we realized the bending and breaking limitations of the material and the effect topology of objects has in contouring-ribbing objects.

Cutting surface = 5400 cm2 Material used = 3787,3 cm Waste Material = 1612,7 cm2 (29,86 %)

Folding Wood

By anna.kulik@iaac.net | Published: December 2, 2011

WOODEN FOLDED LAMP

The main purpose of our project was to find out how to work with material, what are its features. Our technology was folding, and material – wood. So we wanted to prove, that we could really fold it. Work with a material in its extreme points.

After we found the technique, we started creating the lamp, thinking about main purposes: avoidance of the direct light; thoughts about the rhythm; saving materials; using of one-way fold to save time of cutting process; creation of the form from one piece – without the introduction of any other materials (like glue) in between.

PERCENTAGE OF USING MATERIALS

THEORY

A=410*462=189420mm² = 1894 cm²
B= A – lamp hole (r=14mm) = 189420 – 615.44 = 188804.56 mm² = 1888 cm²
C=A-B= lamp hole (r=14mm) = 615.44
D=B/A*100= 0.996 = 99.6%

REALITY ( WITH 2 CM MARGE)

A = 450*502 = 22590mm² = 2259cm²
B = A – 2cm Marge – lamp hole (r=14mm) = 189420 – 615.44 = 188804.56 mm² = 1888 cm²
C=A-B= lamp hole (r=14mm) + 2cm Marge  = 615.44 + 36480 = 37095.44mm² = 370cm²
D=B/A*100S=.835=83.5%
