Lumade - 3D Printed Desk Lamp System

This is our first instructables and our first 3D printing project, and so we are sorry if there are any problems.

In this Instructables, we will explain how to create and build Lumade - 3D printed desk lamp system. 

The starting point of the design of Lumade was to be able to build the same lamp for different uses such as attached with a clamp, wall mounted and positioned on a flat surface like a desk with just changing the number of joints used. 

The instructions start with a first step related to the finishing of the lamp, where some suggestions are provided. Next, a step related to the modification and 3d printing of the joints is shown. Then there is the build, which is separated into 2, getting ready for assembly and assembly.

Supplies

MATERIALS

• 1x Wood Stick (Dim 100 x 2 cm)
• Wood Screws (Dim=4 mm)
• Light Bulb e14 socket
• Cord set e14 (example: IKEA STRÅLA Cord set)
• PP Sheet A3 x 0.5 mm (example: a plastic placemat)
• Rubber washers (1” ODx1/4” IDx1/8”)
• 3D printing filament filament 1 kg spool
• Large head bolt M6 x 25 mm or M6 x30mm
• Optional: Clamp (for the clamp lamp)
• Optional: x 3 wall screws (for the wall lamp)

TOOLS

• Screwdriver
• Drill
• Scissors/ Utility knife
• Wood saw
• Double sided tape
• Measuring tape
• Pencil
• Optional: Sand paper
• Optional: Paint or coating for finishings
• Optional: Paper tape

Step 1: Finishings and Color Combinations

Here, some Suggested color combination are provided:

• Elegant: Silver PLA and Beech wood
• Playfull: Orange PLA and Beech wood
• Japanese: Black PLA and Bamboo

Some precautions in case you want to paint the wood:

1. Make sure you paint on a protected surface so that you don’t make a mess.
2. With the brush cover all the wood following the direction of the grain.
3. Let the wood air dry

Step 2: Choose Your Style - Geometric/Organic/Gear

Choose the style of the lamp you want between Geometric and organic, for both the locking pin is the same f and the instructions in this instructables are specifically for these two styles. The gear style is a collaboration with another group from our university course, the bakery, and it needs springs and different screws and bolts for the assembly.

You can find all the files sorted in folders on our drive too: link

Step 3: Choose the Lampshade: Movable or Fixed

Choose which lampshade you want to make, you can find the files on our drive too: link

Step 4: How to Modify 3d Models (Optional)

First, make sure you choose the joint style you like the most.https://drive.google.com/drive/folders/1_QvfcW3Dm8XiEHkIv65Q_7VzsaQHjGH8?usp=sharing

If you want to use pieces with different dimensions than the ones suggested the 3D models must be modified. For all the models. Step files are provided which can be opened and modified on various CAD programs, such as Fusion360, and Rhinoceros. In addition, the models for the organic style and the lampshade are provided (or will be provided) as Fusion360 files too, these files are parametrically designed. To modify the parametric models we suggest to look at this tutorial by Prusa3D: Parametric modeling in Fusion360 - Original Prusa 3D Printers

The files are on our Drive:

• Step files
• Fusion 360 files

Step 5: 3d Print the Choosen File

1. Download the 3D models from the provided links
2. Choose the material, PLA is fine, technical materials aren’t required
3. Import the models into a slicer, for example, Ultimaker cura
4. Choose the printer you are going to use and choose the parameters for the 3d model
5. Slice the model
6. Start to print
7. Postprocessing

The models are already in the right orientation to be printed

• PrintSettings - 0.4 mm nozzle
• Wall line count: 3
• Infill Density: >20%
• Infill Pattern: Cubic or Gyroid
• Support: Off

POST-PROCESSING:

After the pieces have been printed, they need a bit of post-processing, and the custom supports need to be removed. This page shows in red all the supports that need to be removed from each piece. In the lampshade pieces with a thin surface in the middle of the piece, this surface needs to be cut away with a cutter.

Step 6: Build Part

CUT THE WOODEN POLE into 1x 20 cm, 1x 30 cm, 2x 25 cm (for the lamps without the wooden base you need only the 30cm and the 20cm)

1. Measure the wood pole with the measuring tape
2. Cut the pole with the saw

CUT THE LAMPSHADE

1. Print the lampshade paper model of the lampshade we want
2. Apply the papar tamplate on top of the plastic sheet
3. Apply the paper over the PP then cut along the lines

Step 10: Lampshade Assembly

Two types of lampshade can be created: the fixed lamp and the moving lamp

what do you need:

moving lampshade:

• top piece (Movable lampshade top)
• bottom piece (Movable lampshade bottom)
• connector piece (Movable lampshade light fixture connector)
• cup piece (Movable lampshade cup)
• central body (Movable lampshade central body)
• x6 petals (Lampshade multiple parts template)

fixed lampshade:

• Top piece (static lampshade top)
• Bottom piece (static lampshade bottom)
• Plastic sheet (A3 Static lampshade template)

STEPS:

Moving lampshade

1. Take the six petals and insert them in the pins on top of the bottom piece.
2. Take the central body and press it on top of the bottom piece, being careful to align the pins and the holes between the two pieces, if the fit is too tight the piece can be sanded and if it is too loose some masking tape can be applied.
3. Screw the cup on what was assembled.
4. Take the strala lamp cord and socket and make the socket pass inside the top piece, rest it behind the socket.
5. Unscrew the piece shown in the diagram.
6. Insert the connector piece and screw the piece shown in the diagram to lock it in place. Then take this assembly and insert it in the previously assembled part.

Fixed lampshade:

1. Fold the sheet and connect the bottom part and the lampshade sheet with each other, then connect them from the bottom with the top part of the lampshade, the lampshade is assembled
2. Unscrew the ring from the lamp socket and insert the lamp socket from the top in the lampshade and then screw the ring from the bottom sandwiching the two parts of the lampshade

Step 11: Final Assembly

Connect the lampshade to the structure:

1. Insert the lampshade at the end of the structure and lock it in place, the locking mechanism is the same shown in the passage 4 of the assembly of the structure.
2. Take the cable and use the clips to secure it on the structure.

Plug the lamp in the socket and enjoy !

Step 12: Warnings

JOINTS SCREWING

since the joints have a friction system, they need to be screwed every time they loosen their grip

BREAKAGE OF THE PIECES

in case of breakage the pieces must be replaced

SMALL PIECES

Small pieces can be dangerous for children as they can be easily swallowed

TIGHTENING

After having positioned the lamp on the desired surface, the screws of the joints must be tightened until the lamp stays in the position but not tightening them to the point where it stays can cause undesired movements of the lamp. Tightening it too much makes it harder to adjust it with only one hand.
