3D-Printer – 2023 Addition
3D printing, also known as additive manufacturing, is a process of creating three-dimensional objects by laying down successive layers of material. It has come a long way since its inception in the 1980s and has now become a mainstream technology that is being used in various industries.
A Brief History of 3D Printing The concept of 3D printing was first introduced in the 1980s by Chuck Hull, who is considered the father of 3D printing. He developed the first 3D printing technology, called stereolithography, which used a UV laser to solidify a photopolymer resin. This technology laid the foundation for the development of other 3D printing technologies that we know today. In the 1990s, the first commercial 3D printers were introduced, but they were primarily used for prototyping and not for producing final products. In recent years, 3D printing technology has advanced significantly, and it is now being used to produce final products in various industries such as healthcare, aerospace, and automotive.
Different Technologies Being Used Today There are several different technologies being used in 3D printing today, each with its own unique set of features and capabilities. Some of the most popular technologies include:
- Fused Deposition Modeling (FDM): This technology uses a filament of material that is heated and extruded through a nozzle to create the object. It is one of the most popular and widely used technologies for 3D printing.
- Stereolithography (SLA): This technology uses a UV laser to solidify a photopolymer resin, which is similar to the technology that was developed by Chuck Hull in the 1980s. SLA is widely used in the production of high-precision and detailed objects.
- Selective Laser Sintering (SLS): This technology uses a laser to sinter a powdered material, which is then fused together to create the object. SLS is mainly used for producing complex and highly detailed objects.
- Desktop 3D printers: These are small, compact and affordable 3D printers that can be used for personal or small-scale projects. Pros: Affordable, easy to use, and small footprint. Cons: Limited build volume, lower precision, and lower resolution.
- Industrial 3D printers: These are large and expensive 3D printers that are mainly used for large-scale projects and production. Pros: Large build volume, higher precision, and higher resolution. Cons: Expensive, requires specialized knowledge and maintenance.
- ABS (Acrylonitrile Butadiene Styrene): This is a thermoplastic material that is widely used in 3D printing. It is known for its strength, durability and heat resistance. Pros: Strong, durable, and heat resistant. Cons: Emits toxic fumes when heated, not environmentally friendly, and warps easily.
- PLA (Polylactic Acid): This is a biodegradable thermoplastic material that is derived from plants. It is known for its ease of use and is a popular material for beginners. Pros: Biodegradable, safe to use, and easy to print. Cons: Not as strong or heat resistant as ABS, can be brittle, and has a lower melting point.
- TPU (Thermoplastic Polyurethane): This is a flexible material that is ideal for creating objects that need to be flexible or bendable. Pros: Flexible, easy to print and has a high level of impact resistance. Cons: Not as strong as ABS or PLA, limited color options, and can be difficult to post-process.
Size and Quality 3D printing technology has come a long way and has improved significantly over the years. The size and quality of objects that can be printed today are much better than what was possible a few years ago. The resolution and picoliter of 3D printers have improved, which means that the quality of the objects that can be printed is much better. The resolution of a 3D printer refers to the level of detail that can be achieved in the finished object. A higher resolution means that the object will have more detailed features. Picoliter, on the other hand, refers to the size of the droplets of material that are used to create the object. A smaller picoliter means that the object will have a smoother finish.

let’s dive deeper into how resolution and picoliter of different form factors and materials play a role in the quality of 3D printed objects:
Resolution: Resolution refers to the level of detail that can be achieved in the finished object. A higher resolution means that the object will have more detailed features. The resolution of a 3D printer is measured in microns, and the average resolution of a desktop 3D printer is around 100-200 microns, while the average resolution of an industrial 3D printer is around 50-100 microns.
Picoliter: Picoliter refers to the size of the droplets of material that are used to create the object. A smaller picoliter means that the object will have a smoother finish. The picoliter of a 3D printer is measured in nanoliters (nl) and the average picoliter of a desktop 3D printer is around 50-60 nl, while the average picoliter of an industrial 3D printer is around 20-30 nl.
Form Factors: In general, industrial 3D printers have higher resolution and picoliter than desktop 3D printers because they are designed for high precision, production-level printing. The form factor of the 3D printer plays a role in the resolution and picoliter of the printer, larger and more expensive printers are able to achieve higher resolution and picoliter than smaller and more affordable printers.
Materials: The material used in the 3D printing process also plays a role in the resolution and picoliter of the object. Different materials have different melting points and viscosities, which can affect the resolution and picoliter of the object. For example, materials with a higher melting point and viscosity may produce objects with a higher resolution and picoliter than materials with a lower melting point and viscosity.
In summary, resolution and picoliter are two important factors that determine the quality of 3D printed objects. Higher resolution and picoliter means that the object will have more detailed features and a smoother finish. Form factors and materials play a role in the resolution and picoliter of the object. Industrial 3D printers are able to achieve higher resolution and picoliter than desktop 3D printers, and different materials have different melting points and viscosities, which can affect the resolution and picoliter of the object.

3D Printing Large Data Sets in DNA Molecules
There is even research that has been done to use 3D printing technology to store large amounts of data in a DNA molecule, and then print it into a 3D object. This method is known as DNA data storage.
DNA data storage is a method of storing data by encoding it into DNA molecules. The data is then printed into a 3D object, such as a bunny, using 3D printing technology. The research on this technology is still in its early stages, but it has the potential to revolutionize data storage.
One of the advantages of DNA data storage is its high storage density. A single gram of DNA can store up to 455 exabytes of data, which is equivalent to the data stored on about 455 billion PCs. This is significantly more than traditional data storage methods such as hard drives or flash drives. DNA data storage is also highly durable and can last for thousands of years.
In the specific case of the 3D-Printed Bunny, researchers have developed a method of encoding digital data into DNA molecules, and then using 3D printing technology to print the DNA-encoded data into a physical object. The resulting 3D-printed bunny is a physical representation of the data encoded in its DNA.
It’s worth noting that this method is still in the research phase and is not yet commercially available. Also, the process of encoding data into DNA and reading it back is still not efficient and reliable, and it’s a field of active research.
Imagine if you can what 3D-printing will become in the next 10 years!
3D printing technology is being used to construct large structures such as homes and buildings. The process of 3D printing homes and other large structures is known as construction 3D printing or contour crafting.
Construction 3D printing involves using a large-scale 3D printer to print the structure layer by layer using a building material such as concrete or a mixture of cement and other materials. This process is faster and more efficient than traditional construction methods, and it also allows for more complex and unique designs to be created.
One of the advantages of 3D printing homes and other large structures is the speed and efficiency of the process. Traditional construction methods can take months or even years to complete, while 3D printing can significantly reduce the construction time. This can also result in cost savings as well as reduction in labor.
Another advantage is the ability to create unique and complex designs that would be difficult or impossible to construct using traditional methods. 3D printing technology allows for the creation of intricate geometries and shapes that can be customized to suit the specific needs of the client.
One of the main challenges facing 3D printing technology in construction is the need for large-scale 3D printers that can handle the materials and size required for building construction. Also, it’s important to note that this technology is still in the early stages of development and has yet to be fully adopted by the construction industry.
There are some examples of 3D printed homes and other large structures that have been built, such as the 3D printed office building in Dubai, and the 3D printed houses in China. The future of 3D printing in construction is promising and has the potential to revolutionize the way we build homes and other large structures.
