What is a 3D Printing Pen?

Definition

A 3D printing pen is a small handheld device that allows users to create three-dimensional objects by extruding melted plastic filament. It functions similarly to a traditional 3D printer, but instead of being controlled by computer software and motors, the pen is guided by hand. The pen works by heating the plastic filament to its melting point and then forcing it through an extruder tip. This melted plastic can be shaped into any desired form.

Working Principle

The working principle of a 3D printing pen involves the use of heat to melt the plastic filament and then extrude it through the tip. The pen is powered by connecting it to a power source, such as an electrical outlet or a USB port. Once the power is connected, the pen needs to be warmed up before it can be used. The user inserts a piece of filament into the pen and presses the extrude button to start feeding the filament into the pen. After a few seconds, the pen will begin to extrude the melted plastic, and the user can start drawing or creating objects.

Getting Started

Connecting power

To use a 3D printing pen, it needs to be connected to a power source. This can be done by plugging the pen into an electrical outlet or by connecting it to a USB port on a computer or other device. Ensuring a stable power connection is important for the pen to function properly.

Inserting filaments

Before using the pen, a filament needs to be inserted into it. Filaments are plastic rods that come in various colors and materials. To insert a filament, the user should follow the instructions provided with the pen. Typically, the filament is inserted into a designated slot on the pen, and the user needs to ensure that it is properly aligned.

Warming up the pen

Once the power is connected and the filament is inserted, the pen needs to be warmed up. This is indicated by a temperature light on the pen. The user should wait for the temperature light to indicate that the pen is warmed up before starting to use it. During the warm-up period, the pen heats the filament to its melting point, preparing it for extrusion.

Creating a 2D Sketch

Using stencils or making your own design

To create a 2D sketch with a 3D printing pen, the user has the option to start with a stencil or make their own design from scratch. Stencils can be found online or purchased, and they provide a pre-designed outline that can be filled in with the pen. Alternatively, users can create their own design by drawing directly onto a piece of paper or another surface.

Applying plastic lines on the surface

To create a 2D sketch, the user needs to apply plastic lines onto the chosen surface. This is done by holding the pen close to the surface and moving it slowly to lay down a line of plastic. It is important to apply the melted plastic before it cools to ensure proper adherence to the surface.

Peeling off the plastic from the paper

After completing the sketch, the user can gently peel off the plastic from the paper or another surface. This allows the sketch to be more easily handled and further modified if desired.

Trimming rough edges

If the lines of the sketch have rough edges, they can be trimmed using a pair of scissors or wire cutters. This helps to enhance the overall appearance and refinement of the sketch.

Assembling a 3D Object

Sketching each side of the object

To assemble a 3D object using a 3D printing pen, the user needs to sketch each side of the object individually. This involves drawing the outlines and details of each side separately.

Attaching sides together with plastic drops

Once the sides of the object are sketched, they can be attached together using small drops of melted plastic. The user should hold the pen over the junction of the sides and allow the heat to fuse the plastic together.

Strengthening connections with additional plastic

After the sides are attached, it is recommended to reinforce the connections by applying more melted plastic along the edges. This helps to strengthen the overall structure of the object and ensure its durability.

Freehand 3D Drawing

Creating anchor points

To draw in three-dimensional space, the user can start by creating anchor points with the 3D printing pen. These anchor points act as reference points for the lines that will be drawn.

Lifting the pen to make lines

Once the anchor points are created, the user can slowly lift the pen off the surface while extruding the plastic to make a line. It is important to wait for the first section of plastic to harden before moving the pen to ensure the line maintains its shape.

Making curved lines

Creating curved lines with a 3D printing pen can be challenging and requires practice. The user needs to move the plastic around as it cools to achieve the desired curvature. It may take time to develop the necessary skill and timing to successfully create curved lines.

Practicing to improve skills

Improving skills with a 3D printing pen requires practice. The more the user practices, the more comfortable they will become with creating different shapes and lines. Experimenting with different techniques and designs can help enhance proficiency with the pen.

Modifying and Repairing Objects

Customizing Lego pieces

One of the advantages of a 3D printing pen is the ability to modify and customize objects made from the same type of plastic as the filament. For example, Lego pieces, which are made from ABS plastic, can be easily customized using a 3D printing pen. Users can add decorative details or create entirely new pieces.

Repairing 3D printed objects

Another practical application of a 3D printing pen is repairing 3D printed objects. If an object made on a desktop 3D printer has minor flaws or broken parts, the user can use the pen to repair and reinforce the object. The pen allows for precise control, making it easier to fix small details and strengthen weak areas.

Tips and Tricks

Using a toaster oven to soften edges

If the edges of a plastic sketch are rough, they can be softened using a toaster oven. By placing the sketch in a toaster oven for a few minutes at a temperature just above the melting point of the filament, the plastic will partially remelt and the edges will become softer. Care should be taken to avoid overheating or melting the entire sketch.

Choosing the right temperature for melting the plastic

The temperature setting of the 3D printing pen is crucial for achieving the desired results. Different types of filament require different melting temperatures. It is important to follow the manufacturer’s recommendations for the specific filament being used. Too high of a temperature can lead to excessive melting, while too low of a temperature may result in poor extrusion.

Common Challenges and Solutions

Difficulty in making curved lines

One common challenge when using a 3D printing pen is making curved lines. Achieving smooth and accurate curves requires practice and coordination. Users should take their time and experiment with different techniques to develop the necessary skill. It is also recommended to start with simple, less complex curves before attempting more intricate designs.

Improving timing for cooling plastic

Timing is crucial when working with a 3D printing pen, especially when creating lines or shapes in the air. It is important to wait for the plastic to cool and solidify before moving the pen to avoid deforming or distorting the shape. With practice, users will improve their timing and achieve better results.

Safety Precautions

Avoiding contact with hot surfaces

When using a 3D printing pen, it is important to avoid contact with hot surfaces. The pen and the extruded plastic can become hot during use, and touching them can cause burns. Users should handle the pen with caution and be mindful of where they place it while it is heating or cooling down.

Properly handling the pen and filaments

Proper handling of both the pen and filaments is essential for safety. Users should hold the pen securely and avoid dropping it or allowing it to come into contact with water or other liquids. When inserting or changing filaments, it is important to follow the manufacturer’s instructions to avoid injury and ensure smooth operation.
