Video How to Draw with a 3D Pen: A Step-by-Step Guide

Searching for “video how to draw 3D with a pen” usually occurs when standard picture instructions stop helping to understand how the instrument moves in space. The beginner often faces the fact that the plastic sticks to the fingers, the lines are uneven, and the desired three-dimensional figure in the blogger’s video looks easy, but in practice turns into a shapeless lump. It is the visualization of the process, which is given by video materials, that allows you to capture the critical moment of the plastic feed speed and the angle of inclination. 3D pens relative to the surface.

Unlike traditional drawing, where the instrument is pressed against a flat sheet, here you work in three dimensions, and the slightest change in the position of the brush changes the geometry of the object. Video instructions are indispensable for demonstrating how to hold nozzleSo that the thread lies flat, and how quickly you need to move the device so that the layer freezes instantly. Without a visual example of the pace of work, it is almost impossible to master this skill, since theoretical descriptions do not convey the dynamics of the creation process. polymeric.

In this article, we will analyze which video resources are worth studying in the first place, divide them by the level of complexity and types of materials used. You will learn what to look for when viewing tutorials to avoid repeating other people’s mistakes, and understand why different types of plastic (ABS or PLA) require different approaches to temperature and drawing speed. This guide will be your map in the world of volumetric modeling.

Selection of suitable video resources for training

The first step in mastering the skill should be the right content selection, as not all videos are equally useful for starting. Many authors remove timelapses, where the process is accelerated dozens of times, which disorients the beginner: it is impossible to understand the real speed of the hand. You need materials marked “beginners” or “step by step” where the author draws in real time or with minimal acceleration, commenting on their actions.

Pay attention to what material the author of the video uses. If the title says “PLA plastic” and you have purchased ABS filamentDrawing technique can differ in melting temperature and stickiness. A good training video always contains information about the device settings: heating temperature and feed speed. Ignoring these parameters when viewing can cause your plastic to either be too liquid or, conversely, get stuck in a plastic. extruder.

Platforms like YouTube offer thousands of channels, but there are some that are clearly categorized into animals, architecture, flowers. It’s best to start with simple geometric shapes, so look for videos with the names cube, pyramid, or simple shapes. This will allow you to work out muscle memory and understand how the molten polymer behaves in the air and on the surface.

• 🎥 Look for videos that last 5 to 15 minutes, where the process is not compressed to seconds.
• 🎥 Pay attention to the close-up plan effloretTo see the point of contact of the plastic with the previous layer.
• 🎥 Check if the description contains references to temperature settings for a particular pen model.
• 🎥 Give preference to authors who show the process from different angles, not just from the top.

⚠️ Attention: Don’t try to repeat complex projects with effects and music right away unless the video shows the process of creating the frame. Often a beautiful picture hides the use of internal supports that a beginner may not notice.

Basic drawing techniques: from plane to volume

Mastering 3D painting begins with understanding the difference between drawing on a plane and in the air. In video tutorials, this stage is often referred to as “2D elements.” The essence of the technique is to create individual parts on a special surface (mat, paper or glass), which are then assembled into a single design. This is the foundation without which the transition to a difficult three-dimensional It's going to be very difficult.

The next step is to paint in the air. Here it is important to capture the moment when the plastic ceases to be liquid and becomes solid, but still retains elasticity. The video clearly shows how experienced artists make small pauses or, conversely, accelerate, controlling the cooling of the thread. This is what is used for. temperatureIt is selected experimentally for each color and brand of filament.

One of the key techniques is to create a “framework” or skeleton of a figure. You draw the main lines that define the shape and then fill the space between them. This method allows you to save material and create lightweight, but durable structures. Without the use of a frame, large figures can deform under their own weight even before completely cooling down.

For example, when creating textures (animal hair, dragon scales), the method of “kicking” or fast short movements is used. Slow-motion videos perfectly demonstrate the amplitude of such movements, allowing you to copy the master’s manner of work.

Work with different materials: PLA and ABS

The choice of plastic is not just a matter of color, but a fundamental difference in painting technology. In the video lessons, it is often noted that Plastic PLA The authors use lower temperatures and draw faster, as this material freezes almost instantly. It is ideal for children and beginners, as it does not have a sharp smell and is less demanding on the accuracy of settings.

On the other hand, ABS plastic It requires a higher temperature and often a mat for adhesion. The video shows that when working with ABS artists are more likely to use the technique of “smoothing” hot plastic, as it remains plastic longer. This allows for smoother surfaces and makes the parts joints almost invisible, which is not possible with a rapidly cooling PLA.

There are also biodegradable plastics and composites with the addition of wood flour or metal shavings. Videos with such materials show that the feed speed should be lower, and the movement - more confident, so that the thread does not break. Composite materials can wear out quickly brass nozzlesTherefore, in the description of such lessons, recommendations for the care of the tool are often found.

Characteristics	PLA plastic	ABS plastic
Melting point	190-220°C	230-260°C
Cooling speed	High (instant)	Medium (takes time)
Smells at work	Sweet, weak.	Sharp, chemical.
Strength of the product	Fragile, afraid of heat	High, heat-resistant
Recommendation	For beginners and children	For experienced users

⚠️ Attention: When working with ABS plastic, be sure to ventilate the room. The pairs released during heating of styrene can be harmful for prolonged inhalation in a closed space.

Typical mistakes of beginners when watching lessons

The most common mistake is to try to copy the result while ignoring the shooting conditions. In the video, it may not be seen that the author uses a special substrate that improves the grip of the first layer. As a result, the plastic simply rolls off a smooth table, causing frustration. Always pay attention to the background and surface from which the wizard works on the screen.

The second frequent miss is the wrong angle of the pen. On a monitor screen, the perspective can distort the actual position of the instrument. Beginners often keep 3D pen too vertical or, conversely, too hollow, which leads to an uneven supply of plastic. Try to find a video shot from the operator’s point of view (POV) to see the angle through the eyes of the painter.

The third mistake is to expect the perfect result on the first try. Videos on the Internet are often retouched content, where the moments of digestion of plastic, cleaning are cut out. effloret or correcting errors. Don’t think that professionals get it right the first time; the secret to their success is thousands of hours of practice and knowing the properties of their particular device.

The Secret to the Perfect Layers

Many people forget that the quality of the layers depends not only on the speed, but also on the consistency of pressing the feed button. Uniform pressure is the key to the smooth walls of your figures.

It is also worth mentioning the problem of “snot” – when plastic continues to leak after the release of the button. In good tutorials, they show the reception of "pulling" the pen aside at the end of the line to break the thread. If this is not done, the product will remain ugly drops, spoiling the appearance. polymeric.

Creating complex structures and connections

When the basic figures are mastered, it is time to create composite objects. Videos are taught the “assembly” method at this stage. You create separate parts (head, torso, paws) and then connect them. The main secret that is shown in the videos is the use of “hot” plastic as glue. A drop of molten material is applied to the joint, and the parts are tightly grasped after cooling.

For complex engineering structures, such as bridges or houses, the technique of temporary supports is used. The video shows artists drawing thin strands of supports that hold horizontal elements and then gently cutting them off with a scalpel or breaking them off. This allows you to create overhangs and arches that would otherwise collapse.

Special attention is paid to texturing in advanced lessons. The smooth surface of the plastic looks artificial, so the masters use various nozzles or hatching techniques. Fan nozzles allow you to create wide flat areas that mimic petals or feathers, which significantly accelerates the process of filling large volumes.

• 🏗️ Use the “web” technique to create fine connections between parts.
• 🏗️ Apply the “melting” method to hide the seams between the individual elements.
• 🏗️ Practice creating internal partitions to increase the strength of hollow figures.
• 🏗️ Experiment with the thickness of the thread by changing the speed of the hand.

Tool care and troubleshooting

Even the best quality. 3D pen It requires maintenance, and video bloggers often share life hacks by cleaning. The main problem is the plastic getting stuck inside the heating element. If the plastic has stopped coming out or is jerking, in most cases, a short-term temperature rise or careful needle cleaning (when the device is turned off and cooled) helps.

Cleaning. effloret a mandatory procedure after each session. The residues of plastic at the tip can burn and interfere with the accuracy of drawing. In lessons, they often show how to warm up the pen and gently wipe the nozzle with a dry napkin or a wooden stick, removing the soda. This prolongs the life of the heating element.

If the pen begins to make strange sounds (screaming, humming), this is a signal about a problem with the feeding mechanism. Repair videos often show how to disassemble the body, check the gears, and remove stuck pieces of filament. Regular maintenance ensures that your tool will work like new even after hundreds of hours of use.

⚠️ Attention: Never try to pull stuck plastic from a hot handle with your hands or metal objects, this can cause burns or damage to the Teflon tube inside the mechanism.

FAQ: Frequently Asked Questions

Which 3D pen is best for a 7 year old?

For children of this age, pens that work with PLA plastic Low Temperature (low temperature) They are safe, as the plastic freezes quickly and the risk of burning is minimal. It is also important to have a protective cap on the nozzle.

Why doesn’t the plastic stick to the previous layer?

The temperature is too low or you are painting too fast. The plastic must be slightly sticky at the time of touch to grip the bottom layer. Try to raise the temperature a little or slow down the movement of your hand.

Can plastics be used by different manufacturers?

Yes, it is possible, but the diameter of the thread must strictly correspond to the declared (usually 1.75 mm). Different brands can have different melting points, so when changing the coil always do a test run and adjust the settings. thermostat.

How to remove the smell when drawing ABS with plastic?

Be sure to work in a ventilated room. You can use a carbon filter if it is provided by the design of the handle, or put an air purifier next to it. For home conditions, it is better to switch to PLA or PCL plastics that almost do not smell.

What to do if the handle stops warming?

Check the connection of the power supply and the integrity of the wire. If the heating indicator does not light up, the heating element or thermosensor may have failed. In this case, professional repair or replacement of the device is required, if it is warranty.
