Sometimes called additive manufacturing, 3D Metal Printing Services is transforming the manufacturing industry by cutting costs, offering more complex design options, and reducing waste.Metal finishing, also known as plating, helps manufacturers get even more value from their 3D-printed parts and products by increasing their strength and reducing contact resistance. Because metal finishing and Metal 3D printing service can work together, it’s important to understand how metal finishing adds value in the Metallic 3D Printing process.As you explore what 3D printing is, its uses, and its benefits, it’s also helpful to learn about the benefits of metal finishing and the challenges you might face.

What is 3D Printing?

In manufacturing, 3D printing involves a process where a machine creates a product or part using an additive method based on a three-dimensional digital design.This 3D design is sent to a 3D printer that builds the part or product layer by layer over a base material and then “prints” it.

How Is 3D Printing Used in Manufacturing?

Because of its many advantages, many manufacturing companies use 3D printing to enhance their operations.The speed and cost-effectiveness of 3D printing allow it to support product improvements, both for low-volume and high-volume production. This adaptability makes 3D printing suitable for a wide range of companies in the manufacturing sector.

Here are some of the main ways manufacturing companies are using 3D printing:

Product Enhancements

When you want to improve a product, it can sometimes take weeks or even months to update traditional manufacturing methods. In contrast, 3D printing enables fast product improvements. If you want to upgrade a product you already offer and get it to customers quickly, 3D printing is a great choice. Since you can modify a product’s design in 3D printing software, you can easily replace an old design with a new, improved one.

Low-Volume Production

Besides creating product enhancements, many companies use 3D printing for their low-volume production needs.Since 3D printing makes it simple to produce prototypes and new products, it’s an excellent method for companies looking to test market reactions with short-run part production.Unlike traditional manufacturing, additive manufacturing offers a more flexible development process, allowing you to create prototypes quickly and experiment with various designs.This flexibility not only supports part production but also helps speed up the overall production process and get products to the market faster.

High-Volume Production

In addition to supporting low-volume production, 3D printing is also effective for high-volume manufacturing.Production lines that include 3D printers give manufacturers the ability to make adjustments more quickly to their production processes. Since high-volume production typically focuses on proven products with high demand, you can greatly benefit from the faster speeds that 3D printing provides.

When a company needs to adjust its printing speeds, improve machinery, or modify a product, it can do so much faster than with older manufacturing methods. As a result, companies can reduce delays connected with changes to their high-volume production processes, leading to greater productivity and efficiency.

What Are the Benefits of 3D Printing in Manufacturing?

As 3D printing becomes more popular in the manufacturing industry, it’s clear that it offers a wide range of benefits.The main advantages of 3D printing in manufacturing include cost and waste reduction, more in-house manufacturing capabilities, and greater design complexity.

Here are some of the key advantages of additive manufacturing:

Cost Reduction: One of the biggest benefits of 3D printing is that it is much cheaper than traditional manufacturing methods and machinery.Since 3D printing is more automated than traditional manufacturing, it helps reduce staffing costs. Additionally, 3D printing reduces costs by producing very little waste, leading to lower material costs.
Complex Design Capabilities: Traditional manufacturing processes often limit the types of designs that can be created. In contrast, 3D printing allows companies to produce a wide variety of products. While traditional methods have restrictions on the geometries they can use, 3D printing has far fewer limitations. For example, you can use a 3D printer to create square interior cavities or holes that change direction. Because of these few limitations, you can create products with much greater design complexity.
Waste Reduction: When companies use traditional manufacturing methods, they often generate a lot of material waste due to inefficient practices. Another advantage of additive manufacturing is that it addresses this waste issue. 3D printing uses material only as it goes through the printer’s extruder, allowing companies to use just the amount needed to produce a product or part. This waste reduction helps companies lower material costs and position themselves as more environmentally friendly.
In-House Manufacturing Opportunities: Since manufacturing companies need prototypes before beginning low- or high-volume production, the ability to use 3D printers to quickly make prototypes is a major advantage.Instead of outsourcing to another company to make your prototypes, you can use 3D printers to create them in-house. This capability to produce prototypes in-house can help a company design and produce new products faster.
Creating New Economic Opportunities in Depleted Areas: Because 3D printers reduce costs over time and don’t require a large number of staff to manage them, it is more affordable to have a profitable manufacturing business locally.Instead of outsourcing manufacturing to other countries to cut costs, companies can now establish manufacturing in the United States and avoid high expenses. Due to this local affordability, manufacturers can create more economic opportunities for people living in economically challenged areas.

Where Does Metal Finishing Come Into Play?

Metal finishing is an effective way to enhance the protection of a part or product and improve its functionality. When a company applies a metal finish to a product or component, they coat the item with a layer of metal, which improves its resistance to damage and increases its durability. When printing 3D parts, there are several methods available for applying plating, and there are several benefits to choosing to plate them.

3 Methods for Plating Onto 3D-Printed Parts

Evaporative Coating: This type of coating is designed to maintain the part’s original shape, meaning it is very thin.This coating can provide water resistance or scratch resistance to the part. After evaporating a source material, a company applies the material onto a 3D-printed part within a vacuum chamber.
Autocatalytic Coating: Also known as electroless nickel plating, this method doesn’t require an electric current to apply the metal to 3D-printed parts. Instead, the parts are submerged in a special solution that initiates a chemical reaction. This reaction then helps to bond the nickel to the various parts of the component.
Painting Method: When a 3D-printed part requires a thin coating and can’t be heated for powder coating, a manufacturer will paint the part with liquid paint.The paint is applied using a pressurized vessel, pump, or spray, followed by a thin layer of metal to plate the part.

3 Reasons to Plate 3D-Printed Parts

Increase Structural Strength: One of the main benefits of plating 3D-printed parts is that it increases the strength of the part.By adding a metal layer onto a plastic 3D-printed part, you provide more protection and enhance its durability. Nickel plating, in particular, is known for its excellent corrosion resistance and can significantly increase the lifespan of the product.
Achieve Stable and Low Contact Resistance: Plating helps 3D-printed parts by providing greater stability and lower contact resistance.This lower contact resistance also improves the part’s ability to resist abrasion, wear, chemical damage, and corrosion. Some finishes can even enhance the electrical conductivity of a part.
Gain RFI/EMI Protection: Electronic devices produce radio frequency interference (RFI) and electromagnetic interference (EMI), which can cause other devices to malfunction.Plating helps protect 3D-printed parts used in electronics by creating a barrier that shields against harmful RFI and EMI waves.

Challenges of Metal Finishing for 3D-Printed Parts

Although there are many benefits to using metal finishing, there are also some challenges when applying it to 3D-printed parts.By considering a few factors, you can address these challenges when working with your 3D-printed parts.

Find out more about some of the common challenges associated with plating onto 3D-printed products, as well as some key questions to consider before applying a metal finish to your 3D-printed parts:

Is It Plateable?

One of the main challenges when plating 3D-printed parts is that some plastics are not suitable for plating.In general, it is more difficult to plate plastics with high chemical resistance. Some plastics, like those in the Valox (PBT) family, are particularly challenging to plate. Performance-match polyester resins that you should avoid include PVC, polyethylene, and polyester.

Plastics in the Noryl family can be plated, but they need to be in a blended form.Some examples of these plastics include xenoy, xylex, and urethane. Nylon polymers also need to be in a blended form, with examples like PPS, polypropylene, and PEEK.Although there are some plastics you might want to avoid, there are plenty that are easier to plate.

Some of these include:

Polyethersulfone
Teflon
Polycarbonate
Mineral-reinforced nylon
Phenolic
Diallyl phthalate
Polysulfone
Urea-formaldehyde
Polyacetal

Is It Cost-Effective?

Another challenge is determining whether plating 3D-printed parts is cost-effective.Using non-traditional plastics can significantly increase costs, as they often require more setup processes to apply a metal finish. This can lead to affordability concerns for a company. Instead of using non-traditional plastics, it might be more practical to switch to traditional, cost-effective plastics that are easier to plate.

Additionally, larger parts tend to have higher metal finishing costs. Like non-traditional plastics, larger parts usually require more setup processes to achieve a high-quality metal finish. Because of this, you might want to evaluate the cost of plating larger parts before starting production. If you’re committed to using a larger part, consider working with a metal finishing company that offers cost-effective plating solutions.

Is It Scalable?

If you decide to use non-traditional plastics or larger 3D-printed parts, it could make it harder for your company to scale up production. As the costs and time required for more complex processes increase, you may not have sufficient funds or time to manage these products. Before committing to plating specific types of 3D parts, you should also check whether they will provide the profitability you seek as you grow your production.

Scaling up on your own can be challenging, especially when using non-traditional plastics or specialized finishing processes. Working with a company that specializes in metal finishing can be beneficial. Even if you’re using traditional plastics, a plating company will often have the necessary equipment and processes to effectively apply metal finishes. Thanks to a metal finishing company’s advanced capabilities, you may be able to make plating a previously difficult 3D part more scalable.
