Ba-Ro-La Lampara

For our project, we were assigned the material paper/cardboard and the geometrical manipulation ‘fold’. Our concept for this lamp was inspired by origami and the use of the water bomb technique. The water bomb technique is the basis of numerous types of patters that can be used to make geometric manipulations within a surface. We also wanted to work with the idea of manipulation based on user requirements as well as light studies to help filter soft light through.

For our materials, we used two different thicknesses of cardboard within our lamp design.

MATERIAL LIST:

  • Cartulina Marron 3h. Weight, 40 gr. Measures, 50 x 65 cm
  • Fedrigoni Negro/Negro. Weight, 700 gr. Measures 70 x 100 cm

CUTTING PARAMETERS FOR “Cartulina Marron 3h”:

  • Speed = 100
  • Power = 5

ENGRAVING PARAMETERS FOR “Cartulina Marron 3h”:

  • Speed = 97
  • Power = 16

CUTTING PARAMETERS FOR “Fedrigoni Negro/Negro”:

  • Speed = 100
  • Power = 85

ENGRAVING PARAMETERS FOR “Fedrigoni Negro/Negro”:

  • Speed = 100
  • Power = 50

RECOMMENDATIONS:

For the Cartulina (thin cardboard) it’s necessary to use a wooden base, because we soon learned that the paper was too thin to hold on its own. The thicker cardboard was much easier to cut; it doesn’t need a wooden base.

We also tried multiple times and with different techniques to engrave on both sides of the paper, but that proved to require too precise a job for the machine to complete. We recommend working in one side only.

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.

Scales : Milling

The inspiration for this exercise came from the undulating scaled surface of fish skin. The geometry of the panel breaks from the repetitive nature of real fish scales by the introduction of a point of distortion. This point of distortion is further emphasized by using particular milling strategies.

In order to achieve the desired form, two milling finishings were used. The first strategy used was a parallel finishing. The tool diameter was 12mm ball mill with stepover control as 35% of the tool diameter. The spindle speed was set to 8077 and the cutting speed assigned was 15.24. The total time taken for this strategy was 70 minutes. The second finishing was a radial finish using the same 12mm dia ball mill tool with stepover control as 150% of the tool diameter. The cutting speed assigned was 15.24. The entire mat took 40 minutes to mill with this finishing.

Expandable Structure

The aim of this project was the exploration of the advantages of the FDM printing as a fabrication technique. For this exercise, it was developed a set of prototypes of joints for a mechanical assembly. The concept pursued was to give the structure the capacity to change in length. The design of the joints gave the final piece the ability to expand and retract. Basically there were used three variations of the same joint for the structure.

Milling : Curves

This project was developed to explore the CNC milling processes through different digital designs, materials and tools. The material selected was the Valchromat (595 x 395 x 24) mm. For this exercise it was studied the design possibilities between Rhino and Rhino CAM in order to calibrate them with the milling machine. The concept used for the Valchromat, was to create soft curves that allows the interaction between the layers of the board.

Techniques

Horizontal Roughing: 26mm ball tool, 25 min

Parallel finish: 6mm ball tool,25 min
