What is 3D Printing?

What is 3D Printing and What can it do?

3D printing, also known as additive manufacturing, is a process of creating physical objects from digital designs by layering materials on top of each other. This technology has gained immense popularity in recent years, revolutionising the way we create and produce goods.

To understand 3D printing, it’s important to know how it works. The process starts with creating a digital 3D model using computer-aided design (CAD) software. This design is imported into a slicer, software that converts the model into code that the printer reads to print the model. The printer then reads the digital file and starts printing layer by layer until the final object is created. The materials used for 3D printing can vary from plastics, metals, ceramics, and even food.

One of the most significant advantages of 3D printing is its versatility. It can create objects of any shape and size, making it perfect for creating unique, one-of-a-kind items. It’s also ideal for creating intricate designs that would be difficult to make using traditional manufacturing methods. 3D printing can be used in a variety of industries, including healthcare, architecture, automotive, and aerospace.

Another advantage of 3D printing is its cost-effectiveness. Traditional manufacturing methods require a significant investment in tooling and setup costs. With 3D printing, the need for tooling is eliminated, making it a more affordable option for small-scale production runs.

Cosplay & Hobbies

One of the popular applications of 3D printing in the hobbyist community is cosplay. Cosplayers use 3D printing to create intricate costumes and props that replicate their favourite characters from movies, anime, and video games. They can create parts with precision and accuracy that are difficult to achieve through traditional crafting methods. For example, a cosplayer can 3D print a helmet or armour pieces that fit their body measurements precisely.

Additionally, 3D printing allows hobbyists to create unique and intricate details that are not achievable with other methods. With the help of a 3D printer, hobbyists can print detailed accessories such as swords, wands, or other props that are impossible to make by hand. They can also create customized designs and unique features that make their costumes stand out.

3D Printing is also used for toys and miniatures. Enabling hobbyists to create replacement pieces or custom characters. Model train and RC car communities are just some hobbyists that take advantage of the benefits gained by 3D printing.

Hobbyists also use 3D printing for prototyping and creating replacement parts for various objects. 3D printing enables them to create prototypes of their designs and test them before committing to the final product. This way, they can refine their ideas and create perfect models. Similarly, when a part of a beloved object breaks, they can use 3D printing to create a replacement part, rather than discarding the entire object.


3D printing has emerged as a promising technology in the field of healthcare, offering numerous applications ranging from anatomical models and surgical guides to implants and prosthetics. It allows for the creation of patient-specific models that enable physicians to better understand a patient’s unique anatomy and plan surgeries more precisely.

Additionally, 3D printing enables the creation of customized prosthetics and implants that fit perfectly to a patient’s body. This leads to improved outcomes, reduced recovery times, and better quality of life for patients. 3D printing also allows for the production of drug delivery systems, bioprinting, and tissue engineering, which have the potential to revolutionise medical treatment.

Overall, 3D printing is transforming the healthcare industry, offering innovative and personalised solutions that improve patient outcomes and enhance the quality of care.

3D printing has revolutionized the engineering and production industries, allowing for faster and more cost-effective prototyping and production processes. Engineers and manufacturers use 3D printing to create prototypes, models, and custom parts with precision and accuracy. This technology enables engineers to test their designs and identify flaws or issues before committing to the final product, saving time and resources.

Furthermore, 3D printing is used to produce small-batch or specialised parts that are not cost-effective to produce through traditional manufacturing methods. This allows for greater customisation, flexibility, and reduced waste. 3D printing is also used in the production of jigs and fixtures, which are essential components in mass production. They help to align and guide materials and parts in the manufacturing process, ensuring that the final product meets the required specifications. Overall, 3D printing has transformed the engineering and production industries, offering more efficient and cost-effective solutions for prototyping and production processes.


The cost of 3D printing depends on a few factors. The main costs are the printer itself (including maintenance), printing material and electricity. Decent consumer models start from just over £100 and basic materials start from around £15. Prices vary depending on which printer you buy and what materials you use. For a full guide on what you need to get started, see our beginners buying guide.

While 3D printing has numerous advantages, there are also some limitations to consider. 

  1. Print Quality: 3D printers have come a long way in terms of print quality, but they still can’t match the level of detail and precision of traditional manufacturing methods such as injection moulding. However injection moulding is much more costly. Small details and intricate designs can be challenging to print, and the surface finish may not be as smooth as desired.

  2. Material Limitations: 3D printing is limited by the materials that can be used. While plastic is the most common material, there are limitations on the strength, flexibility, and durability of the printed objects. Advanced materials that have significant strength come at a higher cost.

  3. Print Speed: 3D printing is a slow process compared to traditional manufacturing methods. Depending on the size and complexity of the object, it can take several hours or even days to complete a single print.

  4. Size Limitations: The size of the object that can be printed is limited by the size of the 3D printer’s build volume. Large objects may need to be printed in multiple pieces and assembled, which can affect the structural integrity and accuracy of the final product.

  5. Design Limitations: The design of the object being printed is limited by the 3D printer’s capabilities. Overhanging or unsupported structures may require additional support structures, which can be difficult to remove and affect the quality of the final product.
