Archimedean Spiral Table Lamp
Introduction: Archimedean Spiral Table Lamp
Hello Makers.
I was inspired by the Archimedean spiral to make this lamp. First, I tried to design on paper with make segment design. Then I cut paper and stick all parts with paper tape to ensure the design is feasible or not.
I use Fusion360 to accurately design and fabrication of design with an accurate angle.
Gather all supplies to start making lamps.
Supplies
1> 6 color 2 mm Acrylic sheet ( Yellow,Violet,orange,green,blue,red)
2> Fevi-quick adhesive
3> Glue gun
4> Paper tape
5> Laser cutting machine access
6> Laptop or computer for design
7> White Led Strip & 12 v adaptor
Step 1: Make Paper Prototype
* First, i start to draw lamp designs from archimedean spirals.
* I want to make this lamp from different colors of acrylic.
* The different parts had different lengths & widths and become smaller to bigger from the center to the outer region.
* After designing in 2D, I start to make it in 3D using paper.
* I cut paper pieces in approximate dimensions and join them with paper tape.
* With approximation, the dimension model design looks well.
* After making a paper prototype it is ensured that the design is feasible to make.
* Then choose the material for my lamp.
* I choose 6 different types of acrylic with a thickness of 2mm which is better for laser cutting and easily joinable with adhesive.
* For very accurate fabrication I use to design lamps in CAD software.
Step 2: 3D Design in Fusion360
1. I use fusion360 for 3D design.
2. First, I start to draw all pieces in 2d sketch.
3. Then I extrude all pieces in 2mm thickness.
4. Apply Color to all pieces as per the color available in my acrylic sheets.
5. I arrange 3 same-color parts at 125 degrees to make my design.
6. 492
Similarly, place other parts. Now I have 15 different small assemblies of the same color.
7. Now I arrange them in decreasing angles to make an internal archimedean spiral design.
8. I started from 148 degrees on the outer part and decrease to 125 degrees while going inside.
9. I want to place a light strip inside, so, I designed supports from 2mm acrylic to support the LED strip inside the lamp.
10. Place them in the center of each flat part of the lamp.
11. To make the rigid connection of the side parts with the center part, I design a port to connect it from the inside to make the lamp rigid and stable on the table. This part is made using 3d printing.
Step 3: Preparation for Laser Cutting
* For making this lamp I use different colors of Acrylic.
* That’s why we separate designs for different colors of acrylic for laser cutting.
* I export separately.DXF file for laser cutting as per color code of acrylic.
* Here I attach .DXF file for cutting.
Step 4: Laser Cutting
* For laser cutting, we have 6 color acrylic sheets. we arrange all designs as per the color of acrylic.
* We upload one-by-one designs in the machine and cut acrylic as per design.
* After all laser cutting, we have all 2D parts.
* We cut a total of 45 parts for the lamp and 15 LED supports.
Step 5: 3d Print Part
* To connect side parts to the center part, I design supports which is 3d printed and join 3 acrylic part at the correct angle.
* I attach reference .stl for 3d print.
* Also, attach the Internal support part which is useful to connect the side and center parts connection.
* print "Internal support part " 20 pieces.
Step 6: Test Assembly.
* After laser cutting, I assemble the part with paper tape to ensure the cut angle is as per design.
* it looks good and the joining angles are perfect as per design.
Step 7: Proceed Final Assembly
* Now we move to the final assembly.
* For actual assembly, we use Gluegun and Fevistick adhesives.
* For the outermost part, I use Feviquick for making strong bonds between parts.
* For internal support, I use a Glue gun to stick parts inside.
* Use a few quick-to-joint parts on 125 degrees using 3d printed support.
* Then I stick LED strip supports in the center of the center part with a glue gun.
* Place LED strip inside LED support.
* Then stick all 15 parts at an angle to make an archimedean shape. 646
