Research Seminar Technology

Machine: Laser Cutting Machine

Software: AutoCad

Material: Playwood 3.7mm

Limitations:  10*10 cm, Press fit model

Goal

Use Laser Cutter and it’s sofware

Learn New software (Rhinoceros, Autocad, etc.)

Look for some inspiration on the web (external references)

Step 1

Look for some references on the web (Google, pinterst, etc), sometimes ideas don’t come at the very first time and you can get them everywhere.

Step 2

Start working on the idea, in order to make your idea come to life, do some sketching, remember “Less Ketchup more Sketchup”

Step 3

What are you waiting? once you have the idea and your drawing you to the nearest laser cutter machine and bring to life.

[Rember always use the correct safety gear and be as careful as you can]

Step 4

It’s alive! now finally done, cut and ready to test it.

As you can see the final result worked as it was supposed to do, but remember to be careful at the time of laser cutting, always check the power and the speed of the machine this will be really useful to make sure you cut is perfect and you don’t have a low quality result, also always have in mind the dimensions of your creation, sometimes they can be tricky at the time of cutting.

Remember master make perfect, sometimes things don’t come up like they are supposed to be at the very first try, keep practicing and become a Laser cutting Jedi.

Class: Technology

Machine: Laser cutting Machine

Software: Rhinoceros

Material: Plywood (4 mm approximately)

Limitations:  10*10 cm, Press fit model

Goals:

  • Learn How to use Laser Cutter
  • Learn New software (Rhinoceros, Autocad, etc.)
  • Find out what is Pinterest

Process:  

First of all, the question was what to do. As it was mentioned in the previous class Pinterest is very useful to find inspiration, I decided to start from there. Honestly, it wasn’t really useful. 

So next, after some days of straggling for a masterpiece, I decided not make things difficult and did something that first came to my mind. It was a sligh.

I haven’t done any sketches of my future project, and I have to agree it was a mistake (I will explain it below). So I decided to start drawing in Rhino cause it was the only software I somehow knew. The 2D model looked like this:

As you already can see I made a mistake. the longest pieces don’t have enough holes. 

Then I exported the file to .dxf format and sent to laser cutter, Than was my second mistake: I didn’t make any photos while it was cut. 

After I assembled it, it looked like this:

Because the construction is modular you can do pretty many things with it only using your imagination. For example, Bookshelf with the ladder (special thanks to Andy, that is his idea) :

Results:

I learn some basics of laser cutting, 2D drawing. I made some mistakes, which were crucial for my project. However, if you use some creativity you can make quite interesting things with the material you have.

Class: City and Technology 1st year

Software: Rhino 6

Material: Plywood

Machine: Laser cutter Raylogic AS-1290C

Challenges:

  • learn how to use Rhino 6;
  • create a useful item
  • size of the item should be not bigger then 10cm x 10cm;
  • learn how to make press fit models
  • learn how to use the laser cutting machine

Idea: The primary goal was to create an item, which will be used at home. At the start, the idea was to create a photo frame with lightning inside. However, some changes were made during the process. In the end, the napkin holder was created.

Preparation: Due to the lack of experience in creating items the first step was to create cardboard maquette. All details were fit, so drawing was made in the Rhino 6.

The second step was to cut designed item by using the laser cutter. Due to the miscalculation, the first problem appeared: side detail did not fit. Connector on the side detail was not deep enough to feel for the squire details. So, the redesign was needed.

Was decided to make the connectors deeper. The final side detail is shown below. The two samples were cut to test the connection.

Finally, details of the item were able to connect without glue, and the item reminded the napkin holder, moreover napkin holder is more useful then photo frame.

Introduction:

This is about what it takes to get things done. Every project has a life cycle and the hardest of all the stages is the materialization – the manifestation of the physical project. This is the true challenge and test of a makers worth. Working on the realization of great ideas requires tools and manpower. In this instance both were equal to the task of realizing Elena and Ivan Mitrofanova’s project “Green Spark”

Tools:

Class: Technology, CNC Milling
Software: SketchUp, 3dsmax, ArtCAM, Match3
Material: Plywood 10*10*1 sm

Challenges: Create a tile with your own drawing using cnc machine

IDEA

 

The idea was to create a panel of Soviet hruschovka with its typical inhabitants.

 

DESIGN PROJECT

In the beginning, the base unit with clear dimensions in the sketchpUp was designed, exported to 3dsMax, where entourage and staffing – curtains, grandfather, cat and flower were added. Later, the model was exported to stl.

model from scetchUp

finished model

PREPARING WAY

To create a tile it was necessary to prepare a path for bits in the CNC machine. The path consists of two parts: draft and finish. Rough removes large masses, has a big step, but it works roughly. Pure has a smaller step on all axes, but takes much more time. When creating a path, you need to upload a file stl, specify the thickness of the material, and also the bit for the finishing and roughing path, then in the final path, you can choose the way to create the picture in the last step: one-way, two-way, radial and ect.

TOWER – GNM

Assignment Parameters:
The assignment was to construct a tower using press fit laser cut modular pieces with a dimensional 
limit of 150mm on the length. 

Materials:
Modular patterns were restricted to 3 patterns or modular units.
Laser Cut plywood

Modular Units for Tower Structure

Pre-Design - Conceptual approach:
The concept was based on attainment of the maximum height without compromising the structural 
integrity of the tower frame. with these two parameters as the basis, it was evident that 
additional stability could be attained by the use of a cross-pattern of "beam" structures. 
Horizontal elements were left out. 

Iterations and Re-Design:
In line with the initial concept of simplicity, there were few iterations between the initial 
design and the final version.

Assembly of Tower

Fully Assembled Tower

Troubleshooting:
The initial design had stability issues due to the initial proposal of framing the beams using 
continuous interlocking. This made the initial design heavy. Whereas the interlocking pattern 
was maintained for the base in order to keep the structure stable, the interlocks were discarded 
at the subsequent upper levels, making the structure lighter and allowing for attainment of 
increase height.

Cutting & Assembly:
Cutting out of the modular units was done using a laser cutting machine.
The cutting process took about 45 min.

The Team

Credits:
Whereas the final product was a product of active team work on the part of all team members, 
the cutting work was conducted under the guidance of the course supervisor Ivan Mitrofanov 
since at the time non of the team members could conduct the cutting works independently.
