ROLE

Product design, configuration of CAM files

(group project, 3 members)

DURATION

October - November, 2020

(4 weeks)

TOOLS

Digital: Fusion 360, AutoCAD, Illustrator

Physical: laser cutting machine, CNC router cutting, and 3D printer.

SUMMARY

To learn what it takes to design and execute designs in laser cutting, CNC, and 3D printing, in the Laboratorio de Fabricación Digital class, the premise was to design a bench to be manufactured with a CNC router cutting machine, a lamp made with laser cutting and a 3D printed car.

Bench: CNC router cutting

For the CNC router cutting premise, we proposed to design a bench with three pieces in total: two legs and a seat. We added an openwork representing the initials of the group members as well.

3D MODEL AND RENDERS

The CAD and 3D model were made in Fusion 360.

OPENWORK

Taking the initials of the members of the group (2 M and A), we designed a logo to incorporate into the bench and engrave on the lamp.

PARTS

The three pieces fit together to form the bench, without the need for inputs in the assembly.

BENCH CAM

The CAM file to configure the CNC router machine was made in Fusion 360, based on the 3D model.

PROTOTYPE

Lamp: laser cutting

Regarding the laser cut premise, we designed a four-piece table lamp in MDF and a 3mm acrylic insert. The acrylic insert leaves the screen assembled with kerfing, in addition to having a place to put the light bulb.

PARTS

The lamp consists of a lampshade, a base of two interlocking pieces, and an acrylic insert that fits into the lampshade.

KERFING

We used the kerfing technique, where cuts are made to allow a planar material to be curved, to make the lampshade.

ENGRAVE

The engraving of the logo, in the case of the lamp, is placed on the base.

LAMP CAM

We made a CAM file to set up the laser cutting machine along with a simulation to determine the total cutting time.

Car: 3D printing

Finally, the design of the toy car arises from the interest of working with a morphology that integrates different shapes, fretwork, inserts and perforations. Its production method is 3D FDM printing.

3D MODEL

Like the bench, the 3D modeling was done in Fusion 360.

STRUCTURE

It consists of three pieces: the main structure of the truck and two pairs of wheels with their axles.

UNION

The union between the wheels and the truck is through a socket designed in such a way that it allows them to fit in and not come out.

3D PRINTING

The printing of the truck was through the FDM model, where the material is deposited in a plastic state that is then solidified and printed from the bottom up. The material was PLA plastic with a total time of 2 hours and 40 minutes.
