Chair Parts For Lazer Cutting

In this post, I would be showing a JPEG image of the AutoCAD file which I handed in for laser cutting. In the picture you would be able to see 4 different line colours (black, blue and red, purple). The black represents the outline of the chair parts which would be cut through and the red would have a 2mm recess. As for the other two colours, blue is for the 'through all' cuts within the wood and the purple would be a recess of 4mm.

Each part of the design contains 6 similar shapes. Every 3 pieces would be sticked together accordingly to increase the thickness of the material and would have a mirror image of the other 3 pieces making the design symetrical when assembled together.

Change In Seating Design

Following up in this post is concerning with the seat of the cafe chair which I am modeling up. The material and design of the seat would be changed to make the design different from the usual cafe chair. The seat would be made using 4mm thick steel wire in the shape of a spide web. The jointing of each part would be welded to each other. The outer most layer of the web would have double the thickness to enable it to be slotted in a 4mm groove/recess which would laser cut into the plywood.

1:1 Scale Chair (mock-up)

This is the updated version of the previous chair which has its high backrest chopped off. This design is lighter than the previous design in terms of the amount of material used and is more suitable as a cafe chair. There are going to be some slight changes with the final design which includes some modification to be done with the locking system. With this design, the locking system could be seen from the outside but as for the new design, the locking system would be hidden in between the three layers of wood which I would be using. This gives the cafe chair a more simplified and cleaner look.

Final Concept - Bamboo

My final concept is called Bamboo. This chair is based on the original shape which was a cilindrical design and turned into an octagonal shape to enable production. This chair is hold together using a clip type of locking system on each side of the board. On the base of the chair which holds the seating area, wires will be placed in a criss-cross position to strengthen the seat. Boards are sticked together in two plies for strength.
