Kyoto Student 3D Prints a Plywood Bending Jig

Ryo Kosaka, a maker and pupil at Kyoto Institute of Technological innovation, develops a approach of bending plywood employing 3D printed joints and SPF boards.

As a woodworking approach, bending plywood can make for exclusive styles that are both of those potent and stunning. The only issue is it is not accurately easy…

The regular course of action demands urgent sheets of plywood involving two halves of a mould. And generating that mould commonly demands noisy resources that choose up a whole lot of area.

Now, many thanks to Ryo Kosaka, a maker and pupil at Kyoto Institute of Technological innovation, there is a quieter, additional conservative way. In spot of molds, he takes advantage of a body manufactured of one x four SPF beams and 3D printed joints.

The body is the equal of the “containing” mould 50 %. Performing as the other 50 %, the 1 that applies force to the plywood, is an inflated rubber ball.

Identifying the form of the closing solution is a make a difference of altering the body. And many thanks to Kosaka’s pivoting joints, performing so is simple! Screws fasten two beams to a joint and a bolt retains the angle involving them.

A different seriously interesting attribute of Kosaka’s jig is that you can increase as a lot of bends to a piece of plywood as you want! Just lengthen the body with additional beams and additional joints!

How to Produce and Use a Plywood Bending Jig

In get to take a look at his thought, Kosaka’s initial task was an angled lamp foundation. Its form included two bends, which demanded 3 beams with 3 joints.

The initial action was to style and design the lamp. The ensuing sketches dictated the framework of the body.

Of system, only fastening two beams jointly states very little as to the genuine curve the closing plywood piece will choose. For that, Kosaka established a versatile polypropylene sheet involving two beams, guiding the radius of the curve.

Kosaka then lay quite a few sheets of plywood, painted with glue, within the body. At last, in get to push the plywood versus the SPF beams, he inserted an inflatable rubber ball within the total contraption and pumped it up.

The closing solution, adhering to some submit-processing, was virtually flawless — a sound outcome for a initial path. Because then, Kosaka has experimented with a handful of other styles, which include a curved rectangular shelf.
