In recent years, with the popularity of 3D printing technology, this multifunctional technology has been widely used in various industries. From art, architecture to automotive and aerospace engineering, the applications of 3D printing seem endless, and we believe it will become the next industrial revolution!
The ability of 3D printing to transform creative concepts into physical objects has attracted young minds who are passionate about technology and design. For your child, 3D printing may provide excellent future career opportunities. However, for many parents, this is still a mysterious field. If you are a parent who wants to expose your child to this fascinating technology, here are some information worth knowing.
What is 3D printing?
3D printing is a technology that uses professional software and equipment to “print” 3D models. Depending on the industry and purpose, the size of the printer can range from small desktop models to professional equipment capable of printing metal parts for cars and airplanes.
Currently, the most popular printing materials are plastics or resins. However, with the latest developments in this rapidly developing technology, machines are now capable of printing sandstone, paper, metals, and even ceramics.
The rise of home 3D printing
With the increasing popularity of 3D printing, many families now have desktop printers. Children are excited about materializing their imaginative ideas into physical models and designs. Parents are naturally concerned about the latent risks associated with this advanced technology. However, through careful preventive measures and supervision, 3D printers can provide children with valuable insights into emerging technologies that are shaping various industries. This exposure can help children see themselves as future innovators rather than passive bystanders.
How does 3D printing work?
3D printing involves multiple technologies, depending on the machine you purchase and the materials it uses. Regardless of the type of machine, the first step is to create an initial model on a computer. Typically, this involves sculpting the model using professional 3D modeling software such as ZBrush, Blender, or Maya. However, models can also be selected from online databases. After the model is completed or selected, it can be transferred to the printer.
Most 3D printers you can purchase use plastic filament, which is usually wrapped around a reel. The plastic is extruded from a removable nozzle controlled by a computer after being superheated. Building from bottom to top, the printer will create the model layer by layer, a process called “additive manufacturing”. Depending on the complexity and size of the model, printing may take hours or even days to complete.
What are the applications of 3D printing?
The potential applications of 3D printing seem limitless. Although most machines only use plastic filament for printing, recent developments mean that some printers are able to print using metal, ceramics, paper, wood, wax, or sandstone. Therefore, 3D printing has found applications in a wide range of industries from art to engineering. In the production of dental products, this technology is revolutionary. It allows for cheaper, faster, and more accurate production of crowns, braces, dental implants, and dentures. We have even seen some creatives using this technology to print cheaper alternatives, where medical prosthetics or orthotics are too expensive.
The latest development of 3D printing metals has found applications in aerospace manufacturing. Companies like NASA and Rolls-Royce have successfully used this technology to print engine parts and further refine their designs.
In addition, 3D printing has become a popular choice for making architectural models. Historically, architects would carefully replicate models with wood or foam, but 3D printing allows accurate and detailed models to be produced in a shorter time. In addition to the above applications, 3D printing is also used in the following fields:
- Glasses
- Prosthetic limb
- Theater and movie props
- Interior design and furniture
- Automotive engineering
- Paleontology and Archaeology (reconstruction of artifacts and skeletons)
- Forensic and police work (reconstruction of damaged evidence)
For children, 3D printing is an excellent way to unleash their creativity. From toys and art to custom prosthetics, the only limitation of this technology seems to be their imagination.
Is 3D printing safe for children?
When it comes to children’s 3D printing, several safety factors must be considered.
- As part of the printing process, some printers release small amounts of plastic particles into the air. This is not only harmful to breathing, but may also worsen the condition of patients with asthma or other respiratory problems.
- The other two health issues involve moving parts and heating nozzles. Like any other machinery with moving parts, there is a risk of clamping body parts, clothing, or hair.
- In addition, the nozzle temperature of the printer may exceed 260 ° C, which may cause serious burns if touched.
Considering this, when the printer is running, children must not be left unattended.
If the printer you choose to purchase is not fully enclosed, it needs to be placed in a well-ventilated room, such as a garage. Once the printer starts running, it is best to avoid gathering around the device to watch the process to avoid inhaling any particles. Instead, you can set up a webcam for children to watch the entire process if they are interested.
In addition, the following points need to be noted:
- Let the child wash their hands after each use of the printer.
- Keep the surrounding area clean. To avoid generating any air particles, use a damp cloth.
- Avoid eating, drinking, chewing gum, or handling contact lenses while the machine is printing.
- If it’s okay, keep the window or door open while printing.
- Use gloves and safety glasses when operating the printer.
- Check the printer before each use. Do not use the printer if it appears damaged or if you notice any exposed wires.
What to consider when choosing a 3D printer for children?
When introducing 3D printing to children, several factors need to be considered. In addition to cost, you also need to consider the design and size, as well as the type of plastic it uses.
If you want your child to use a printer, it is worth choosing a machine that is not too heavy. Large heavy printers can become a potential danger if the child tries to move them at any stage.
Fully enclosed printers are also preferred because they help reduce the spread of airborne particles during printing.
In addition, you also need to check the type of plastic used by the printer. If you want to make toys and small tools that children can use, ABS and PLA are considered the safest plastics for children.
1. ABS is the plastic used to make LEGO building blocks. It is a durable plastic that is easy to print, strong enough for outdoor use.
2. PLA is a non-toxic bioplastic. As this plastic is environmentally friendly, it will decompose if exposed to the natural environment for a long time. However, it is also odorless, easy to print, and resistant to warping.
