Is a 3D pen a Toy
or a Serious tool?

3D pens are nothing new by now. Nonetheless, some people remain wary of their effectiveness. Is it possible that they’re nothing more than children’s toys? Let’s dig a little deeper.

Over the years, the 3D printing industry has seen a lot of creativity and advancement. The 3D printing pen is one such invention. It’s given youth, authors, hobbyists, and talented designers a sense of fun and usability. The device is almost mystical, as it allows you to draw a 3D physical model out of thin air. Even, one might wonder whether a 3D pen is a toy or a serious weapon. The real answer is that it could be either one or both! A 3D pen, unlike typical writing and drawing tools, is packed with a plastic string rather than ink. The majority of pens sold in stores use standard polymer rods, which are purchased by printers that use layer-by-layer technology.

 

 

 

A 3D pen is a device that allows you to draw in the air. It may appear to be a kind of sorcery, but it is just another technical advancement in the field of 3D modeling. A device that will forever change the definition of “drawing,” because it allows you to draw not just on paper, but also in space! The computer looks like an FDM printer, but it has a whole range of applications. It allows you to not only practice drawing and conduct some experiments in the making of imaginative masterpieces, but it also allows you to solve a variety of daily problems. There are two kinds of 3D pens on the market right now: cold and hot. The first are photopolymers, which are quickly printed polymerizing resins. Various polymer alloys in the shape of a bobbin tube with a plastic thread are used in “hot” pens.

A 3D printing pen is a bulkier variant of a regular pen that uses plastic filament instead of ink or lead. It works like a portable version of a 3D printer, drawing real objects out of thin air. 3D pens are not powered by a computer or software; instead, they are guided by your hand when you create a model from your imagination. Batteries or a wire attached to a USB port or a socket power most 3D printing pens.A special opening in the back of the case is where the filament is inserted. The built-in system automatically feeds ink to the extruder, where it is heated and extruded to the outside in molten form. Since the metal tip of the print head will reach a temperature of 240 degrees Celsius, simple safety precautions should be followed when dealing with the product.

Despite the fact that 3D pens have a built-in fan to speed up the solidification of plastic, carelessness with the product is linked to the possibility of burns. The pen’s proportions make it easy to bear with one hand. Minor noise generated by the built-in mechanism does not interfere with 3D modeling. The FDM-pen allows for fast rod replacement, allowing you to mix and match colors and materials when drawing. Specific ABS or PLA materials should be used there. ABS plastic is most often found in daily life. It is long-lasting, wear-resistant, and suitable for bonding plastic products. A mild shrinkage and the appearance of a distinctive burnt plastic odor are among the disadvantages. PLA patterns are more qualitative, and can be explained by its low melting point. 

Furthermore, since this compound is made from natural materials, it is biodegradable. Around the same time, the filament’s application life is noticeably reduced.

How does a 3D Printing Pen Work?

Depending on whether it’s a hot pen or a cold pen, a 3D printing pen operates in one of two ways. Plastic filament close to that used in 3D printers is used in a hot pen. The filament is injected into the pen and heated before it melts before being extruded.

The liquid filament is quickly cooled by the air as it exits the pen. One can draw desired objects on any surface or in thin air in this manner. If you’ve ever used a hot glue gun, you’ll recognize how hot 3D pens operate. Here are a few hot pen examples:

Who is a 3D printing Pen For?

A chemical reaction is used to transform a liquid to a solid in a cold pen. Since the ink is a photosensitive pigment, this is conceivable. UV light is used to solidify it until it leaves the end of the ink. SLA resin 3D printing is similar to this process. Here are a few examples of cold pens:

  • IDO3D Vertical

  • CreoPop3

     
     
     
     
     
     
     
     
     
     

Children

The best 3D pen for kids is one that doesn’t emit a lot of heat and is thus better to use. Cold pens are therefore appropriate for children, but hot pens are also acceptable if used under adult supervision.There are also “warm” pens. There are hot pens that are made of a special plastic that melts at a lower temperature. The following are some good candidates for children’s pens:

  • IDO3D Vertical
  • 3Doodler Start (warm)
  • 3Dsimo Basic (warm)

Hobbyists

Hobbyists are people who like doing things for fun. A nice hobbyist 3D pen is one that has a lot of features and is reasonably priced. Support for different fabrics, reduced temperature variation, and speed settings are all common features. Buttons for both extruding and unloading may be used in such pens. Here are a few popular hobbyist pens:

  • MYNT3D Printing Pe
  • 3Dsimo Kit
  • 3Doodler Create

Professionals

3D pens are the most difficult to use. They usually have a lot of accuracy and a lot of settings that can be adjusted. Take a look at these pens for two examples:

  • 3Doodler Pro
  • 3Dsimo Multipro

Application Areas

3D printing pens can be used in several different applications:

3D printing repair: 3D pens, when used in conjunction with a 3D printer, are suitable for minimal post-processing and repair work on 3D items. They’re particularly useful in difficult-to-reach regions. Hobbyists and experts would most likely learn from this.

Function in the arts and crafts: 3D pens are useful in crafts, sculpture, and fine art. Developing elevated decorative patterns deserves special mention. Naturally, people of all ages are welcome to participate in such events.

3D modeling and prototyping: A 3D pen will make product creation in fields like jewelry, apparel, and automobile much simpler. The ability to visualize simple 3D forms immediately is incredibly useful for brainstorming as conceptualizing, and it is appropriate for both hobbyists and professionals.

Teaching: A 3D pen is an extremely useful learning tool, especially in areas such as mathematics (for drawing geometric shapes), architecture (for modeling), and science (for visualizing physical models like atoms and organs).

PRO

Of course, a 3D printer may produce complicated shapes by precisely replicating the elements of the programmed model. However, a 3D printer has a range of distinct advantages:

  •  First and foremost, there is the issue of weight. The weight of modern devices starts at 40 grams. Even an infant will safely hold them in their hands. The device’s small size and ergonomic nature allow it to be taken on business trips or vacations.
  • Some machines are fitted with rechargeable batteries,allowing them to be used further from the power supply network’s access points.the effects of 3D printing for yourself.

 

 

 

 

 

 

  • Furthermore, the pen’s compact scale helps you to draw even in difficult-to-reach areas.
  • The system greatly broadens the definition of fine art. Even if you are not a fan of painting, your children will enjoy this gadget. The pen would be a fantastic gift for kids. It will not only help to brighten up free time and give contemporary television a new perspective, but it will also help to expand the child’s worldview, improve visual thinking, and fine motor skills.
  • Affordability is another point in favour of 3D pens. A pen costs a fraction of what a laptop printer does and has equivalent features. You should purchase several copies for your family at once and try out the effects of 3D printing for yourself.

3D Printing Pens vs 3D printers

In the following cases, a 3D printing pen is preferred to a 3D printer:

  • Creating freehand sketches of objects and free sketch modeling ideas
  • Creating imaginary versions rather than attempting to create them in CAD applications
  • Children are being taught the principles of 3D printing.
  • Visualizing concepts during the early stages of product creation (even before prototyping)

 

Summary

Since the system is free of heating elements, it can be trusted even by small children. Under the impact of a strong built-in ultraviolet light source, the photopolymer solidifies immediately. Applying fanciful sketches to bare skin areas with cold ink reduces the possibility of burning yourself. The substance has no odor and comes in a wide range of colors. Transparent, biodegradable, colored, elastic, conductive, and even glow-in-the-dark resins are available. We hope you can see how a 3D pen can be a toy, a weapon, or both now that you’ve seen some of the core ideas behind 3D printing pens. In the end, it comes down to the pen and the person using it.

When it comes to the school, painting, or product creation, a 3D pen may be a valuable tool. When used for crafts, paintings, and general entertainment, however, it is a toy.
