Essential Information About Anodizing Aluminum

Aluminum is one of the strongest metals in existence. It is used in a wide range of applications. However, in most cases, anodized aluminum is applied in place of bare aluminum. ddprototype is one of the companies offering anodizing aluminum services. However, before you even consider hiring a company for the process, there are things you need to know about anodizing aluminum.

Essential things you should know about anodizing aluminum

Below are some essential things you need to know about aluminum anodizing;

What is anodizing?

Anodizing is a process used for changing the surface chemistry of metals and various types of substrates. The main point of anodizing is to protect the metal or substrate surface from issues like corrosion. Anodizing also helps enhance the aesthetic qualities of the metal. Using the right kind of anodizing material can also help the metal to resist scratching.

How do you need to prepare for aluminum anodizing?

Before you begin the process of anodizing, you first have to prepare the metal. You do this by cleaning the surface of the metal thoroughly. You can use an alkaline solution for this task. After cleaning it thoroughly, you also have to rinse it off properly. The preparation process does not end here. The top layer of the aluminum also has to be eliminated using chemical etching.

Also, once you have cleaned and rinsed it, you have to place it inside a bath of an electrolytic solution. Sulfuric acid is one of the most popularly used electrolytic solutions for this task.

What is the role of the electrolytic solution in anodizing?

The electrolytic solution is used to trigger an electrochemical reaction on the surface of the metal. The solution features a lot of positive and negative ions. The positive charge converts the aluminum into an anode.

On the other hand, the negative charge is attracted to the positive. The electrochemical reaction triggered results in the formation of pores on the aluminum surface. The pores are a result of the escaping of the excess positive ions.

The pores are typically formed in a geometrically regular pattern. As the reaction continues, the pores start to erode into the substrate, allowing the surface to combine with the negatively charged oxygen ions. This process results in the formation of aluminum oxide. The process through which this layer is formed is called passivization.

What is the role of aluminum oxide?

The aluminum oxide created on the surface of the metal is referred to as the barrier layer. This layer acts as a defense for the metal against further reactions with oxygen and other chemicals. This is the reason why anodized aluminum is resistant to issues like corrosion and rust.

Are there further treatments after aluminum is anodized?

After the anodizing process, the metal has to go through post-treatments or procedures. An example of such treatments is coloring. Most of these post-treatments roles are to give the metal some desirable properties to improve its aesthetic appeal.


Various industries carry out the anodizing process on aluminum and other metals. The anodized aluminum can be applied in a wide range of industries and products. For instance, it can be used for construction. Anodized aluminum is more durable than bare aluminum because of the improved resistance to damaging elements like corrosion.

3D printing technology: Beneficial uses in the manufacturing sector

3D printing’s manufacturing applications may not include printing atoms, but even that goal isn’t unreachable. The technology had evolved significantly since the 1980s when its idea was initially conceived.

Indeed, its rapid development is not unconnected to the rapid growth of certain markets today. You probably wonder how valuable 3D printing could be to your manufacturing effort. Here are some practical applications of 3D technology for a manufacturer.


Before you start ordering expensive titanium and wood treatment reagent, how about prototyping with 3D technology instead? The value of 3D printing to prototyping across all industries can’t be overstated. Its proper name is “rapid prototyping.”

The name is because of how fast it makes the task of getting your idea in physical shape. You don’t need expensive working models when a 3D printed model can demonstrate your idea to investors. Rapid prototyping isn’t a new idea to the manufacturing scene; it’s already happening and becoming increasingly rapid.

Low-Demand Manufacturing

There’s no doubt that 3D printing is too slow for manufacturing large-volume products with massive demands. However, low-volume products with low demand are fair game with a 3D printer. It’s a valuable technology to test run new product lines with uncertain market demand.

You’ll find such type of fabrication mostly with high-value goods that command low demand. It satisfies the need for customization of look and function without raising the price sky-high. Technological advancements in 3D technology also mean that high-volume product fabrication may not be a pipe dream for the future.

Parts and Components

Sometimes, the crank of your power tool breaks down, and you have to wait for a week until a new one arrives. 3D printing saves you the stress of the wait and allows you to continue the job within a few minutes. Start your printer, load up the crank design, print it, replace the old crank with it, and continue your work.

3D technology simplifies the problems of industrial holdups by providing an easy alternative for replacement parts. You can quickly make valuable repairs to your tools and equipment without spending too much money. Many small-scale manufacturers also innovate fast by using the technique to reduce the development costs for their products.

It’s not just small businesses that benefit from 3D technology either because even Porsche is using it. Massive companies like Airbus can replace complex plane interior components by simply printing the exact dimensions. In 2018, Ford won major honors for its lightweight assembly lift assist that was 50% cheaper than its counterpart using FDM.

Lightweight Products

Weight is one of the great enemies of manufacturers and consumers worldwide. Replacing some heavy parts of your product with lighter 3D printed parts is a new hobby for manufacturers. With the right 3D printed casing and material components, you can make your final product extremely lightweight.

Final Thought

As 3D technology continues to evolve, its status as the future of manufacturing also continues to increase. You are certain to benefit from the capabilities of printing atoms once that evolution is complete.


What Are The Uses Of The Standard 3D Printer Enclosures?

3D printers have an open design that cannot enclose the device with its walls. The design and mechanism of operation play a role in reducing cost as well as size. However, the two features may not limit the printer’s capability in any way. If you are using PLA material to print, then an open printer would do. On the other hand, if you are using the ABS or polycarbonate materials to print, then you will need an enclosure. In this blog post, we furnish you with details regarding the uses of the standard 3D printer enclosures. A 3D printer enclosure is a material that covers your printer to improve the quality of printed products.

This blog post highlights the pros of running the 3D printer in the enclosure. We also outline tips for setting up an enclosure.

A 3D printer enclosure is more defined by its functions and not the actual physical structure. It majorly serves as insulation for the print area. The device also protects the printer from several factors, such as the external environment. This minimizes the impact of the printer’s interaction with its surroundings.  The printing process will benefit from the printer enclosure. At the same time, the environment can easily be protected from precarious by-products emitted after the printing process.

3D Printer Enclosures

There are countable types of 3D printer enclosures. The enclosures are made from various materials, including fiberglass, plastic, and studio tents. Every element has a degree of impact on the quality of printing. With that said, it is vital to note that the most critical aspect you should consider when choosing a 3D printer enclosure is its efficacy.

Does it provide you with the long term and short term benefits it should? How easy is the maintenance? If you are printing with ABS, then you should avoid a draft. You should also focus more on capturing the heat generated via the print nozzle of your printer.

Other than that, it is also essential to understand the vast importance of having 3D printer enclosures.

Here are some pros of 3D printer enclosures.

  • Protecting the prints from drafts as well as fluctuating temperatures
  • Protecting the 3D printer from dust
  • Trapping fumes emitted in the printing room
  • The enclosure’s metal enhances fire safety

If you are using a PLA filament to print, then you may not need a 3D printer enclosure. This is because the material benefits from cooling, thereby allowing the layer to set in. As a result, the overhang will be eradicated. If the printer is sealed in an enclosure, then the heat will be trapped into the device. This can easily keep the filament from cooling. You may end up with poor quality prints, particularly with the finer details. On the other hand, ABS seems to benefit more from a 3D printer enclosure. Because the commercial 3D printers have relatively heated units that can hold the temperature when printing, an enclosure would come in handy.

3D Printer Enclosures

In Closing

While you can print without the 3D printer enclosure, you need to arm your machine with the protector because of the impending dangers that may attack it. Delamination can be frustrating. You, therefore, should provide your printer with protective gear. Enclosures are majorly a great way of making the printing experience more comfortable.
