3D printed Virtual Reality gear

Our target was to design a VR headset that can be fully 3D printed. The soft parts such as the straps and foam can be printed using a flexible filament. However, the real challenge was to design it in a way that it doesn’t need any screw or another external component (this needs few drops of glue only). Use of lenses at 37mm. The first version can be found at the end of the post. The length of the smartphone should be at 140mm approximately. This VR headset is fully adjustable, but if you still have a small issue with the focus try to switch places on the parts 2a and 2b. There are two types of straps with length at 190mm and 250mm. Using the short straps, there are extensions (part 9) that should be printed also. This model is better than a simple Google Cardboard or a VR box and improves the experience of the virtual reality games.

3D printed stylus pen

A capacitive touch screen is made by an array of sensors and is able to identify a contact through the electrical voltage variations. A simple stylus pen works as a conductor and transmits an electrical charge between your finger and the screen. Then a microprocessor detects the electrical changes and estimates the coordinates of the touch. Thus, using a conductive filament is possible to produce functional 3D printed stylus pens for smartphones and tablets. This post is to demonstrate how the stylus tip should be.

Close up of a 3D printed mini stylus pen with a conductive filament

First of all, the conductive filament should not be too resistive because the signal could be too weak. Also, when the microprocessor receives the contacts and estimates the locations, it is possible to ignore areas thinner than 1/4 inch. This is to avoid unwanted activations and is considered as the size of a human fingertip. As it is illustrated in Figure 3, an angle of 20 to 45 degrees is recommended for the tip, since it needs a flat contact and at this angle is more convenient to hold the stylus and use it. A soft rasp can be used to refine the tip and make a smoother surface. The hole in the middle helps to minimise the area of the contact, it is possible to work without it too.

Most of the simple earplugs cannot be attached to the ear for a long time. In the proposed design, the holders keep the earplugs attached to the ears, so they can be used also during sleeping or in other daily activities. Also, a valve can be used for the reduction of the pressure; it can be open or closed. Flexible materials are recommended for the main parts and PLA for the valves.

3D printed force/pressure sensors

Make low cost 3D printed sensors

Recently, advanced conductive materials have been presented for the 3D printing of electrical circuits. These new types of materials have extended the possibilities of 3D printing. A low-cost conductive filament with high resistivity can be used for various low-voltage applications such as force/pressure sensors. When pressure is applied, the contact area between the two conductive materials is increasing and the total resistance is decreasing (Fig 1).

 

 

Figure 1. The structure of the sensor.

The simplest circuit for the measurement of the voltage output is illustrated in Figure 2 and 3. This connection called as a voltage divider. In this circuit, a 10 kOhms resistor was used.

Figure 2. Voltage divider.

Figure 3. Circuit connection

 

Below you can find download links for the STL files of the sensors for a 3D printer with a dual or single extruder (Fig. 4 & 5). Using a single extruder, each printed layer should be glued.

Figure 4. 3D printed pressure sensor with a dual extruder.

Figure 5. 3D printed pressure sensor with a single extruder.


To test the pressure sensor, a calibrator was developed (Fig. 6). STLs of the calibrator are also included at the end of this post.

 

Figure 6. The structure of the calibrator.

 

Applying 5 weights (each one was 1 kg) in a pressure sensor printed with a dual extruder, the measurements were extracted (Fig. 7).

 

Figure 7. Applying 5 weights.

The results are not linear, they follow an inverse exponential attitude. In higher values, more force is needed for less change of voltage. Every printed sensor does not present the same behaviour, the voltage output could be different for each one. However, the produced 3D printed pressure/force sensors have similar behaviour with commercial Force Sensitive Resistors (FSRs) sensors and with minimum cost; each one is estimated in a few cents.

Code (Output voltage):

float reading = 0;
int dt = 20; 
unsigned long t=0;    

void setup() {
Serial.begin(115200);
}

void loop() 
{
t=millis(); 
 reading = analogRead(0);

 Serial.println(reading*(5.0/1023));


while((millis()-t) < dt) // Making sure the cycle time is equal to dt
  { 
  // Do nothing
  }

}

 

One way to calibrate the sensor is by applying weights and recording the output voltages. After, using interpolation the relative weight or force can be estimated. More weights yield better accuracy. Calibrator code can be downloaded at the end of the post. The code is based on repetitive procedure asking a weight and calculating the average voltage. Finally, a smoother could be employed for better results.
