3D printing has revolutionised the manufacturing industry, with plastic and metal being the two most popular materials used in the process. The choice of material depends on the specific requirements of a 3D printing project. Plastic is the most commonly used material for 3D printing due to its low cost, ease of manufacture, versatility, and water resistance. Metal 3D printing, on the other hand, has gained popularity for its unique combination of practical and aesthetic properties, offering complex end-use capabilities. Metal 3D printing is a more complex process than plastic printing, requiring post-processing to improve the mechanical properties and appearance of the object.

What You'll Learn
Plastic is the most popular 3D-printing material
The plastic 3D printing market is much larger than the metal market. Plastic is used more than metal in almost every manufacturing process, and innovations in thermoplastic 3D printing are producing solutions that are well-qualified for end-use parts production.
The popularity of plastic as a 3D-printing material is due to its low cost, ease of manufacture, versatility, and water resistance. Plastic is also more readily available than metal and is much cheaper. It has a wide variety of choices for 3D printing, including hybrid materials that mix a base like PLA with a powder that gives them a different colour or surface structure.
Plastic is also easier to work with than metal. Metal 3D printing is a more complex process than plastic printing, and post-processing is required to improve the mechanical properties and appearance of the object. This post-processing is more labour-intensive and expensive than with plastic, where finishing work can usually be done by hand.
Overall, plastic is the most popular 3D-printing material due to its accessibility, versatility, and ease of use compared to metal.

Metal 3D printing is more complex and expensive
Secondly, metal 3D printing is more expensive due to the high costs of metal powder. The price of metal powders can range from $50 to $100 per kilogram for standard metals such as stainless steel or aluminum, to over $1000 per kilogram for specialty metals such as titanium alloys and precious metals. The high cost of metal powder directly increases the overall price of metal 3D printers and printing services.
Thirdly, metal 3D printing requires more post-processing than plastic 3D printing. Metal 3D printed objects often require post-processing to improve their mechanical properties and appearance, which can be labour-intensive and costly. Plastic 3D printed objects, on the other hand, can easily achieve the desired outlook and texture by hand or with simple tools.
Lastly, metal 3D printing has higher temperature and power requirements than plastic 3D printing due to the higher melting point of metals. Metal 3D printing also requires precise temperature control and an inert gas environment to prevent metal oxidation at high temperatures, further increasing the complexity and cost of the process.
Overall, while metal 3D printing offers unique advantages such as the ability to produce complex parts with intricate geometries, it is more complex and expensive than plastic 3D printing due to the high costs of metal powders, complex manufacturing processes, increased post-processing requirements, and higher temperature and power needs.

Plastic is cheaper and easier to work with
Plastic is the most popular 3D printing material, with polymer plastics being the most widespread. This is because plastic is readily available, cheaper, and easier to work with than metal.
Plastic 3D printing is more accessible to beginners as it is more affordable. The machines are less expensive, and the materials cost less than metals. Metal 3D printing, on the other hand, requires a substantial investment, with printers costing hundreds of thousands of dollars and metal powders being more expensive than plastic filaments.
The printing process for plastics is also simpler and less time-consuming. Plastic has a lower melting point than metal, resulting in lower temperature and power requirements. Metal 3D printing requires a high level of sophistication, and the printing process can be more complex and time-consuming. Metal must meet casting and forging standards, resulting in higher material properties than plastics.
Post-processing for plastic 3D printing is generally easier and less labour-intensive. Designers can achieve the desired outlook and texture of the object by hand or with simple tools. In contrast, post-processing for metal 3D printing is required to improve the mechanical properties and appearance of the object, and it often involves more complex and expensive procedures.
Plastic 3D printing is widely used for prototyping, educational purposes, consumer products, and lightweight applications. It is suitable for detailed models and complex geometries, but it may require post-processing to meet aesthetic standards. Metal 3D printing is used in industries where material properties are critical, such as aerospace, automotive, and medical, due to its superior strength and durability.

Metal 3D printing offers practical and aesthetic properties
Metal 3D printing offers a unique combination of practical and aesthetic properties. It is a versatile manufacturing process that can create physical objects from a digital model using metal-based materials. Metal 3D printing enables the production of lightweight, durable, and flexible parts with superior mechanical properties and improved hardness compared to traditionally manufactured metals.
One of the key advantages of metal 3D printing is its ability to handle high melting points with precision. This allows designers to create prototypes and small batches of parts that would be challenging, or even impossible, to produce using conventional methods. Metal 3D printing also speeds up the product development cycle and reduces time-to-market. Companies can create tools and reproduce components in-house, cutting waste and supply chain risks while enabling rapid prototyping and faster mass production.
Metal 3D printing offers a range of aesthetic options as well. Metal alloys such as aluminium, stainless steel, titanium, and cobalt chrome are commonly used, providing high strength, corrosion resistance, and excellent thermal properties. For example, aluminium is highly flexible and strong, making it ideal for automotive, biomedical, and aerospace applications. Stainless steel is widely used across industries for its high strength and corrosion resistance, while titanium is used for printing larger, complex parts.
Additionally, metal 3D printing can fabricate parts from superalloys suited for extreme environments. For instance, Inconel 625 is a strong, stiff, and highly corrosion- and heat-resistant nickel-based superalloy used in turbines and rockets. Copper, another metal used in 3D printing, is an excellent conductor of heat and electricity, making it valuable for heat sinks, power distribution components, and manufacturing equipment. With its unique properties and applications, metal 3D printing offers a blend of practical functionality and aesthetic versatility.

Metal 3D printing has exciting, complex end-use capabilities
Metal 3D printing is a highly effective method for creating complex, custom parts that would be difficult and expensive to produce by other means. It is particularly useful for parts with complex internal geometries and structures. Metal 3D printing can be used to create lightweight parts with excellent stiffness and performance. This is achieved through advanced CAD techniques, such as topology optimization and generative design. The geometric complexity of a part has almost no effect on the manufacturing cost, which is a huge advantage.
The two most common metal 3D printing processes are Direct Metal Laser Sintering (DMLS) and Selective Laser Melting (SLM). These processes are used to create end-use engineering products and are considered the standard for metal 3D printing. SLM is particularly useful for precise, geometrically complex parts. Most materials available today can be used with SLM machines, and they are used in a wide variety of applications, from healthcare to aerospace. DMLS/SLM can create highly optimized, organic structures from high-performance metal alloys, such as aluminium, steel, and superalloys.
Other metal 3D printing processes include Binder Jetting, which is faster than SLM and DMLS as it can print multiple parts simultaneously. Bound Powder Extrusion (BPE) is a newer method that uses metal powder bound together in waxy polymers, which is safer and easier to handle than loose powder.
Metal 3D printing is an expensive process, and it is also limited by the availability of certain metals. However, it is a valid manufacturing option for complex parts that would otherwise be challenging to produce.
