The cost of 3D printing plastic varies depending on several factors, including the type of filament, brand, quantity, and technology used. FDM 3D printing filament prices for standard materials like PLA or PETG typically range from $20 to $50 per kilogram, while specialty filaments can cost between $40 and $60 or more per kilogram. ABS, a common material for stronger parts, usually falls within the same price range as PLA. Composite filaments, such as wood, metal, or carbon fiber-filled options, tend to be more expensive than generic filaments. The cost of 3D printing technology itself also varies, with hobbyist FDM machines starting at a few hundred dollars and industrial-scale printers costing significantly more.

What You'll Learn
Cost depends on plastic type
The cost of 3D printing plastic depends on various factors, including the type of plastic, the application, and the required precision. Plastic 3D printing is generally more affordable than metal 3D printing, making it a popular choice for hobbyists, educators, and industries.
One of the most common plastics used in 3D printing is PLA (polylactic acid). PLA is known for its ease of use, affordability, and versatility. It is commonly used for creating toys, decorative items, and non-functional prototypes. The cost of PLA filament typically ranges from $10 to $20 per kilogram, making it a cost-effective option for those starting with 3D printing as a hobby.
Another commonly used plastic in 3D printing is ABS (acrylonitrile butadiene styrene). ABS is known for its strength, heat resistance, and ductility. It is often used for creating replacement parts, Lego bricks, and durable components. ABS filament is usually priced similarly to PLA, making it a good option for those seeking improved material properties without a significant increase in cost.
More advanced plastics, such as PETG (polyethylene terephthalate glycol-modified), offer enhanced durability, temperature resistance, and food safety. These properties make PETG a popular choice among professionals, particularly in food packaging applications. However, the added benefits of PETG come at a slightly higher cost compared to PLA and ABS.
For applications requiring the highest performance, PEEK (polyether ether ketone) and PBI (polybenzimidazole) are the most advanced thermoplastics available. These materials offer exceptional strength, temperature resistance, and wear resistance, making them ideal for high-performance applications. However, PEEK and PBI are also the most expensive plastics for 3D printing, reflecting their superior capabilities.

Cost depends on brand
The cost of 3D printing plastic depends on a variety of factors, including the type of plastic, the brand, and the specifications. The brand of the 3D printer can also influence the cost of the filament, as some printers are designed to only take their own brand of filament.
Polylactic acid (PLA) is a popular filament material, known for its ease of use, biodegradability, and range of colours. It is typically priced between $15 and $27 per kilogram, depending on the brand and blend. For example, Hatchbox PLA on Amazon is priced at around $25 per kilogram.
Acrylonitrile Butadiene Styrene (ABS) is another commonly used material, offering durability, impact resistance, and heat resistance. ABS filament costs around $20 to $27 per kilogram, with the Hatchbox brand priced at $22 per kilogram on Amazon.
Polyethylene Terephthalate Glycol (PETG) combines the benefits of PLA and ABS, providing good strength, flexibility, and chemical resistance. Overture PETG filament is priced at around $21 per kilogram on Amazon.
Nylon is a flexible and chemically resistant filament, ideal for outdoor parts such as nuts, gears, and bolts. As nylon does not have generic brands, it tends to be more expensive than standard filaments. MatterHackers and Puzzlebox 3D are known manufacturers of nylon filament.
Other factors that can influence the cost of 3D printing plastic include the quality, dimensional stability, and colour. Composite filaments, which blend two materials with different properties, can vary significantly in price depending on the additives used.
It is important to consider the brand and range of filament costs compatible with a specific 3D printer when purchasing printing materials. Online retailers offer a wide selection of brands and prices, while local suppliers provide the advantage of seeing and touching the filament before purchase.

Cost depends on quantity
The cost of 3D printing plastic depends on the type of plastic and the quantity purchased.
For FDM 3D printing, 3D printer filament prices for everyday materials like PLA or PETG range from $20 to $50 per kilogram. Buying in bulk from reputable manufacturers can result in significant savings, sometimes up to 20-40%. For example, nylon materials for SLS printing cost around $100/kg, but bulk pricing can reduce this by more than 50% for larger quantities.
Specialized engineering or support filaments can be more expensive, ranging from $60 to $120 per kilogram. Metal-filled filaments, which contain fine metal powder, tend to be heavier and more expensive than standard plastics. Wood-filled filaments, such as those made with a PLA base and powdered wood additives, are another option with various choices like bamboo, cedar, and coconut.
The type of printer also influences the cost of printing plastic. Desktop SLA printers typically start from $2,000 to $3,000, while an SLS printer usually costs upwards of $10,000. FDM printers offer the greatest variation in price, from a few hundred dollars for hobbyist machines to $2,000-$6,000 for higher-performance desktop printers.
Additionally, it's important to consider the cost of consumables, maintenance, and energy consumption when calculating the overall expense of 3D printing plastic.

Cost depends on printer type
The cost of 3D printing plastic depends on several factors, including the type of printer, the type of filament, and the brand.
For example, the two most commonly used filaments in 3D printing, PLA and ABS, typically cost between $20 and $27. On the other hand, specialty filaments can range from $40 to $60 per kilogram. Third-party filaments are generally cheaper than branded filaments, and premium brands can charge higher prices due to their advanced production techniques and quality control.
The diameter of the filament also matters, as it needs to be compatible with your printer for smooth and reliable printing. The most common diameters are 1.75mm and 2.85mm (or 3.00mm).
Additionally, the type of printer you use will impact the cost. For instance, industrial 3D printers can work with a variety of materials, including plastics, metal wires, resins, powders, and even living cells. The specific technology used by the printer will also affect the cost, as different methods are used to produce 3D printed parts with polymers.
Finally, it's worth considering the overall cost of 3D printing ownership, including the upfront cost of the printer, repair costs, electricity, and maintenance. If you're only printing for fun, buying your own printer might be a better investment than using a 3D printing service. However, if you need access to large-scale printers and advanced capabilities, hiring a service may be the better option.

Cost depends on labour
The cost of 3D printing plastic depends on a variety of factors, including the type of printer, the cost of labour, the type and brand of filament, and the quantity purchased.
FDM 3D printers are generally the cheapest option for printing simple prototypes in small batches. The cost of FDM filament ranges from $20 to $50 per kilogram for standard materials like PLA or PETG, and $60 to $120 for specialised engineering or support filaments. However, FDM printing can be labour-intensive, especially for complex models that require manual post-processing such as sanding.
SLA 3D printers offer higher resolution, better quality, and a wider variety of materials, but are more expensive. Entry-level SLA resins cost around $50 per litre, while most professional options range from $150 to $400. SLA printing is less labour-intensive than FDM, as it uses a laser to cure liquid resin into hardened plastic, resulting in a smoother surface finish.
SLS 3D printers are the most expensive option, typically costing $10,000 or more. The nylon material used in SLS printing costs around $100 per kilogram, but bulk pricing can reduce this by over 50%. SLS is the least labour-intensive process, as parts require only simple cleaning to remove excess powder.
In addition to the cost of the printer and materials, labour costs can include the time spent setting up and maintaining the printer, as well as designing or sourcing 3D models. These factors can significantly impact the overall cost of 3D printing.
