What is 3D printing, and how does it work?
3D printing, also known as additive manufacturing, creates three-dimensional objects from a digital model or file by building up successive layers of material.
One of the biggest advantages of 3D printing is its versatility and ability to use a wide range of materials. The materials that 3D printers most commonly use include:
- Plastic: The most commonly used plastics in 3D printing include ABS, PLA, Nylon, PETG, and TPU. These materials are popular because they are readily available, inexpensive, and easy to work with.
- Metals are becoming increasingly popular in 3D printing, with materials such as titanium, aluminium, and stainless steel. Metal 3D printing can be used to create complex shapes that are difficult or impossible to manufacture using traditional methods.
- Ceramic materials, such as alumina, zirconia, and porcelain, are used in applications that require high strength and resistance to heat and wear, such as medical parts and high-temperature aeronautical components.
- Composite materials, such as carbon fibre, fibreglass, and Kevlar, are used in 3D printing for applications that require high strength, stiffness, and resistance to impact.
Common types of 3D printing
There are several types of 3D printing, each with advantages and disadvantages. The most common types include:
- Fused Deposition Modeling (FDM): This is the most popular type of 3D printing. It involves melting a thermoplastic filament and extruding it through a nozzle to create the object layer by layer.
- Stereolithography (SLA): This method uses a laser to cure a liquid resin, layer by layer, to create a solid object.
- Selective Laser Sintering (SLS): This method uses a laser to sinter a powdered material, layer by layer, to create a solid object.
- Direct Metal Laser Sintering (DMLS): This method uses a laser to sinter metal powder, layer by layer, to create a solid metal object.
- Digital Light Processing (DLP): This method uses a digital light projector to project an image of each object layer onto a vat of photopolymer resin, which is then cured by a UV light.
Each method has benefits and limitations, and the choice of method depends on the specific application and the desired material properties.
Factors affecting the cost of 3D printing
- Choice of materials: The type of material used significantly affects the 3D printing cost. Common materials like PLA and ABS are more affordable, while speciality materials such as metals and high-performance polymers are considerably more expensive.
- Printer type: The cost of 3D printers varies widely, from affordable desktop printers for hobbyists to high-end industrial machines. The initial investment in a printer can be a substantial expense.
- Print Volume: The size and complexity of the printed object will impact the cost. Larger and more intricate prints require more material and time, thus increasing the overall price.
- Printing Speed: Faster print speeds often come with a higher price tag in terms of the printer’s cost and operational expenses due to increased energy consumption.
- Post-Processing: Depending on the desired finish, post-processing steps (e.g. sanding, painting, or assembling multiple parts) can add to the overall cost.
- Design Complexity: The complexity of the 3D model affects printing time and material usage. Simplifying the design can reduce costs.
- Printing Resolution: Higher-resolution prints demand more precise printers, which can be more expensive. However, lower resolutions may not achieve the desired quality.
Is 3D printing expensive in the UK?
The cost of 3D printing in the UK is relative and depends on various factors, as mentioned above. Here’s a breakdown of the situation:
Affordable Entry-Level Options: There are numerous cheap desktop 3D printers in the UK market, catering to hobbyists, educators, and small businesses. These machines are reasonably priced and offer a cost-effective way to get started with 3D printing.
Material Costs: Basic 3D printing materials like PLA and ABS are generally affordable and widely accessible in the UK. However, exotic or speciality materials can be considerably more expensive.
Service Bureaus: For those who don’t want to invest in a 3D printer, there are 3D printing service bureaus in the UK, such as the one we have at Ignitec. We offer printing services at competitive rates, allowing you to pay only for the prints you need without the upfront costs of a printer.
Long-Term Value: While the initial investment in a 3D printer might seem significant, it’s essential to consider the long-term value. Owning a printer provides the flexibility to iterate designs and produce parts in-house, potentially saving money over time.
Industrial Applications: For industrial-grade 3D printing, especially in aerospace, automotive, and healthcare sectors, the costs can be higher due to the need for advanced printers and materials. However, the benefits in terms of customisation and rapid prototyping often justify the expense.
What are the benefits and challenges of using 3D printing for manufacturing?
There are several benefits to using 3D printing for manufacturing, including:
- Customisation: Allows for customisation and personalisation of products, which can be a significant advantage for companies that need to produce products in small quantities or with unique features.
- Speed: Facilitates fast, on-demand manufacturing, which can be a significant advantage for companies that need to get products to market quickly.
- Cost: It can be cost-effective for small production runs or highly customised products, eliminating the need for expensive tooling and moulds.
- Flexibility: Allows for the creation of complex shapes and structures that would be difficult or impossible to manufacture using traditional methods.
- Shorter lead times: Reduces the need to seek suppliers overseas, thus mitigating supply chain fragility and providing additional cost-benefit advantages.
- Sustainability: Enables the recycling and repurposing of materials, reducing the need for virgin materials and minimising environmental impact. In addition, 3D printing uses only the exact amount of materials required to create a part or product, thus generating less waste.
3D Modelling Case Study
Ignitec’s collaboration with Autonomous Robots Ltd to develop and design an autonomous underwater vehicle utilised 3D modelling to overcome the challenges presented by a project of this scope and nature. Our collaboration resulted in a groundbreaking new concept for underwater surveying made possible by our ability to validate the concept and its functionality by successfully integrating electronic components, design efficiency, and manufacturing practicalities.
However, there are also several 3D printing challenges when used for manufacturing:
- Material limitations: While a wide variety of materials can be used in 3D printing, some materials are unsuitable for this process. This includes flammable natural materials (e.g. paper, wood, organic textile fibres), hard natural materials that are heat resistant (e.g. stone), and certain metals (e.g. gold and silver)
- Size limitations: The size of the object that can be 3D printed is limited by the printer bed size. Larger objects may need to be printed in multiple parts and then assembled, which can be time-consuming and challenging.
- Quality control: 3D printed parts may have surface imperfections or inconsistencies in material properties that can affect the quality and performance of the final product. Quality control measures must be implemented to ensure that each part meets the required specifications.
- Cost: While 3D printing can be cost-effective for small production runs or highly customised products, the price per unit can be high for larger production runs. This is due to the cost of materials, the time it takes to print each unit, and the cost of maintenance and repair of the printer.
