Modern creative technologies have made great strides forward, turning fantasies into tangible reality in just a few minutes. 3D pen has become one of the most popular tools not only for children, but also for professional designers, allowing them to draw in the air and create three-dimensional objects. Whether you're picking up this gadget for the first time or are looking for inspiration for a new crafts from 3D pens, then the right start on the path is critical to achieving a quality result.
The process of creating three-dimensional figures is radically different from traditional drawing on paper, requiring the development of a new type of motor skills and spatial thinking. You will have to learn to control the plastic feed speed, heating temperature and pressure on the button so that the lines lie evenly and do not spread. That's why the first craft should be simple, but interesting enough to reinforce basic skills in working with molten polymer.
In this article we will analyze all the nuances of choosing materials, setting up the device and step by step creating several unique products. You'll find out why polylactide (PLA) is considered an ideal material to start with, and how to avoid common mistakes that beginners often make when trying to fasten structural elements. Get ready to turn simple colored threads into real works of art.
Choice of material: which plastic is best for starting
The first and most important step before starting the creative process is the correct choice of consumables, since not only the appearance, but also the safety of your crafts from 3D pens. There are many types of plastic on the market, but for novice users and children, the best option remains PLA plastic. This material is made from renewable raw materials such as corn starch or sugar cane and does not release toxic substances when melted.
Unlike ABS plastic, which requires high heating temperatures and often has an unpleasant smell of burnt plastic, polylactide melts at lower temperatures and hardens almost instantly. This allows you to create complex structures without fear that the lower layers will begin to deform under the weight of the upper ones. In addition, PLA It has a pleasant matte texture and a wide color palette, which makes it indispensable for creating bright souvenirs and toys.
⚠️ Attention: When working with ABS plastic, be sure to use a well-ventilated area, as the fumes released when styrene is heated can cause headaches and allergic reactions.
For those who plan to create functional objects or decorations, it is worth paying attention to PETG or special filaments with additives (bronze, wood, glow in the dark). However, remember that it is better to experiment with exotic types of plastic after you have mastered basic drawing techniques and understand the behavior of standard material in your 3D pen.
- 🎨 PLA - biodegradable, safe, ideal for children and decorative figurines.
- 🔥 ABS - durable, heat-resistant, but requires good ventilation and acetone for gluing.
- ✨ PETG — flexible, durable, suitable for creating bracelets and functional parts.
- 🌙 Phosphorescent — glows in the dark, great for creating night lights and decorations.
Preparing the workplace and setting up the tool
Quality of the future crafts directly depends on how well your workspace is organized and the tool is correctly configured. Before turning on the 3D pen, make sure that the table surface is protected from hot plastic drops, for which a silicone mat, special paper or even a regular sheet of cardboard is ideal. Using a protective coating will not only save the furniture, but will also make it easy to separate the finished structural elements after they have cooled.
Setting the temperature is a key point that beginners often ignore, which leads to frequent plastic jams or, conversely, to its leakage by gravity. For PLA plastic the optimal range is usually between 190 and 210 degrees Celsius, while ABS requires heating to 230-250 degrees. If your 3D pen equipped with a display, set the parameters recommended by the filament manufacturer and wait for the nozzle to completely warm up before starting extrusion.
It is also important to check that the feed channel is clean and that there are no old plastic residues that may have hardened inside the mechanism. If the handle has not been used for a long time, it is recommended to “drive” a few centimeters of new material through it to clean the channel and ensure uniform flow. Only after this can you begin to create your first three-dimensional figure.
Always unplug your 3D pen immediately after finishing work, even if you plan to take a short break, to prevent oxidation of the plastic inside the heating element.
Basic drawing and joining techniques
Making it complex crafts from 3D pens is based on several fundamental techniques, the development of which will take no more than 15-20 minutes of practice. The basic principle is to draw flat parts on a surface (mat), which are then connected together in a vertical plane or glued together using hot plastic. There are two main approaches: drawing freehand in the air and creating from a template, and each has its own advantages.
The technique of drawing from a template (or stencil) is ideal for creating symmetrical and geometrically accurate objects. You place a piece of paper with an outline drawn on it under a clear protective mat and simply trace the lines with melted plastic. Once cool, you remove the flat pieces and join them edgewise, using the “liquid” plastic from the handle as glue, gently pressing the joints for a few seconds until they set.
Drawing in the air requires greater coordination of movements and an understanding of the physics of solidification of the material. Here it is important to move the handle at such a speed that the plastic lies in an even thread, without sagging under its own weight, but also without stretching to the point of breaking. Travel speed and feed speed must be synchronized: the faster you move your hand, the more actively you need to feed the material so that the line remains continuous and uniform.

Master class: creating a “Panda” keychain
To reinforce your skills, we suggest creating a cute and simple crafts — a keychain in the shape of a panda, which consists of several flat parts assembled into a three-dimensional figure. This project is great for practicing joining techniques and working with small parts. You will need black and white PLA plastic, as well as a little patience for careful assembly.
Start by drawing the outlines: on the protective mat, draw two identical circles for the head, two ovals for the ears, two semi-circles for the paws and one oval for the body using white plastic. Then fill in the insides of the pieces by drawing lines close together or using the "shading" technique so that the surface is continuous. Use black plastic to add characteristic spots around the eyes, the eyes themselves and the nose, and also outline the contours of the ears and paws for contrast.
After all the parts have cooled and are removed from the mat, begin assembly. Take one of the round head pieces, apply some hot plastic to the edge and press the second piece down, leaving a small gap to fill the inside. Through the hole at the top (where the ears will be), fill the inside with pieces of plastic or painted mesh to give the figure rigidity, then close the hole and attach the ears and paws.
| element | Plastic color | Quantity | Technique |
|---|---|---|---|
| Head (base) | White | 2 pcs. | Outline + Fill |
| Ears | Black | 2 pcs. | Outline + Fill |
| Eye spots | Black | 2 pcs. | Outline + Fill |
| Paws | Black/White | 4 pcs. | Outline + Fill |
⚠️ Attention: When connecting parts, do not touch the pen nozzle, as its temperature can reach 200 degrees or higher, which will cause burns.
Top ideas for inspiration and skill development
When the basic techniques are mastered and the first craft made from 3D pens successfully assembled, an endless field for experiments opens up before you. You shouldn’t stop there, because the capabilities of this tool allow you to create both miniature decorations and large-sized interior objects. The main thing is to gradually increase the complexity of the tasks and try new textures and shapes.
One of the popular directions is the creation imitation knitting, when plastic is applied in wave-like movements, creating the effect of a knitted fabric. This “knitwear” can be used to make incredibly realistic caps for mugs, phone cases, or even clothes for dolls. Another interesting option is to create wireframe models of architectural structures or geometric shapes, where the accuracy of lines and angles is important.
The secret to a perfect surface
To ensure the surface of your craft is smooth rather than ridged, try to move the pen at a constant speed and use a lower temperature (on the lower end of the range for a given plastic), which will allow the plastic to flow more smoothly, but will not require sanding.
- 🏰 Architectural models — Eiffel Tower, bridges, castles (vertical training).
- 🦋 Insects and animals - butterflies, beetles, birds (working with symmetry).
- 💍 Jewelry — rings, pendants, earrings (use of flexible PETG).
- 🎄 Holiday decor - snowflakes, Christmas tree decorations, cake toppers.
Typical beginner mistakes and how to fix them
Even experienced craftsmen sometimes encounter problems during their work, but beginners make a number of common mistakes that are easy to correct if they know their cause. Most often, problems are associated with incorrect temperature: if the plastic does not stick to the previous layer, it means that it has cooled too quickly or the heating temperature is insufficient. In this case, you need to slightly increase the heat or warm up the joint with a stream of hot air (carefully!).
Another common problem is “beards” or dangling strands of plastic that spoil the appearance. crafts. This happens when you release the feed button too late or move the handle too slowly. Train yourself to release the button a split second before the end of the line and make a sharp movement with the brush to the side to break the thread, or use a special scraper to remove excess.
If the plastic stops feeding and a cracking noise is heard, there may be a “stuck” inside the mechanism due to sudden cooling or the use of low-quality filament. In such a situation, you should not press the button with force; it is better to increase the temperature by 10-15 degrees and try to slowly push the material. If this does not help, you will have to disassemble the feed mechanism according to the instructions for your model 3D pens.
The main secret of success is not to be afraid of ruining a part. 3D painting makes it easy to correct a mistake by simply melting the defective area and applying a new layer of plastic on top of it.
Is it possible to refill a 3D pen with plastic from another manufacturer?
Yes, in most cases you can use different brands of plastic as long as the diameter matches the standard of your pen (usually 1.75mm). However, the quality of the raw materials may vary, so when changing manufacturers it is recommended to experiment a little with the heating temperature, as additives and dyes can affect the melting point.
How to store leftover plastic so it doesn't spoil?
PLA plastic is hygroscopic, meaning it absorbs moisture from the air, which can lead to bubbles and poor print quality. Store leftover threads in sealed bags with a silica gel desiccant bead in a dry place, away from direct sunlight.
What should I do if the plastic leaks out of the spout before heating?
This is normal for some handle designs. Always check that there is no protruding plastic in the nozzle before turning it on. If there is one, carefully trim it or press it back in, but don't turn on the pen until you're ready to draw to avoid the cork drying out.
How long does it take to dry a 3D craft?
The plastic hardens almost instantly, within a few seconds after leaving the nozzle. However, to gain full strength and complete cooling of the entire structure, especially if it is voluminous and dense, it is recommended to wait 5-10 minutes before active use.
