The task: 

  • Construct a tower using press-and-fix technology.


  • Only three types of elements, not bigger then 150mm x 150mm.
  • All elements must be cut out on a laser cutting machine from a sheet of plywood in size 900mm x 600mm
  • The goal of building the highest tower.

Used equipment:

  • Laser cutter Raylogic AS-1290C

Used material:

  • Plywood

Team members:

Ilya – teamleader

Valeria – team member

Irina – team member

Process of working:

From the very beginning, the team was interested in the reliability and aesthetic appearance of the whole structure. The name of our laboratory reminded us of the image of the Shukhov Tower and we decided to use it as a prototype.

We cut out the first version of parts from thick cardboard for better understanding what form of parts is better to use

As shown in Picture 1, a 3×3 cm square was proposed as a connecting element. The team agreed that this connecting element would not ensure the reliability of the structure.

Therefore, the team leader suggested using a larger connecting element, and also introduce spacers as the third element, which would help fix the base of the structure.

In Picture 2 you illustrated the 2nd variant of the connecting element, which was cut from the defective material for the sample.

As a result, we found that we badly calculated the size of the grooves on the connecting element, where we planned to insert the beams. Fortunately, we found a hint due to the marriage of the material used: a small hole in the material turned out to be in the place of one of the slots (picture 3). We took this new groove shape to continue.

 To create the spacer, we decided to use the main beam, adding an additional groove (picture 4). The third detail of the design was the “leg” in picture 

During the work on the project, the connecting element received a new hexagon shape. This new form allowed us to save space on the workpiece to accommodate a larger number of beams.

And it’s our result. We also want to say thank you to Alexey, Maxim and Semen for the help!!!

Limitation of the work:

Our team faced the problem with laser. Half of the details were not cut. However, overall we like the look of the tower and its stability. 

The task: Construct «some useful thing» using press-and-fix technology and cut it using a laser cutting machine.

Used equipment: Laser cutting machine. Model A3-1200C.

Used material: Plywood.

Process of working:

I like art-deco. So I decided to make some accessory for home in this style. For example, a pen box.

I started by creating a layout in Rhino. The result was this side of the pen box.

When one side was ready, I began to do slots. And here I discovered my mistake: when I was making creating the pattern, I didn’t take into account the size (material thickness 3.8 mm) slot.

Because the work on creating a picture in Rhino was very painstaking and difficult for me (after all, this is my first independent experience of using Rhino), I decided to get out of this situation by increasing the scale of the thing itself.

For this, I increased the width of the part from 8 cm to 11 cm.

Create coupling elements was not such an easy task. I couldn’t move edge joints from And I did them by myself. As a result each side of each detail was unique. I placed all parts on the layout in sequential order to avoid build errors.

Because I cannot work with the Laser cutting machine for reasons of health, Alexey and Valeria helped me with cutting. I am very grateful for their help and understanding. Here you can see how they were cutting my model.

And it’s a result.

It was an interesting task, but there are a number of drawbacks when working with the laser cutting machine:

  • It can be useful for creation really unique things if you need them. The task takes a lot of time and it can be not economically viable – if you just need a pen box you loose less resources when you just buy it in a shop.
  • You need to use high quality materials and equipment.
