How to Choose the Right Finish for Your Online 3D Printed Part

The finish you select when ordering parts via online 3D printing is a very important factor affecting the final look, feel, and performance of the product. The correct finishing treatment can play an essential role regardless of whether you are producing a functional prototype, a display model, or a customized end-use part.

Your choice for your online 3D printing project surface finish will depend on your application, the aesthetics you desire, and the material you have selected. There are so many surface finishes available that knowing the advantages and disadvantages of each one will help you to make decisions which improve both look and life span.

Understanding 3D Printing Finishes

Finishing, the very last step in printing, is the procedure through which the printed part is made more refined. It has a positive impact on looks, durability, and performance. A finish can be as basic as sanding or as sophisticated as professional-grade coating or polishing, depending on whether the material is plastic, resin, or metal.

The surface of 3D printing finishes is smoothened, the strength of the parts is raised, and the color and the texture are changed, which is what the usual finishes are made for. The following are some of the most important aspects of 3D printing finishes:

• Smoothing surface

• Strengthening the parts

• Introducing colour or texture

• Treating the surface to be wear and chemicals resistant

Types of 3D Printing Finishes

1. Mechanical Finishing

A mechanical finish is one that physically alters the surface of the printed part. This method is most suitable for totally eliminating the print lines that are visible and creating a smooth or glossy appearance.

The common methods are as follows:

• Sanding – Prepares the surface for painting or coating by reducing its roughness.

• Polishing – Gives a glass-like shine, especially for resin prints.

• Tumbling – Small parts are slowly and smoothly processed in bulk.

Best suited for: The plastic and resin models where the look is of primary importance.

2. Chemical Finishing

With chemical treatments, the surface layer is either dissolved or melted, thereby creating a uniform texture that does not harm the very fine details.

The common methods are as follows:

• Vapor Smoothing – Usually applied on ABS prints; results in a glossy and sealed surface.

• Chemical Polishing – Applied to metals in the process of getting rid of microscopic irregularities.

Pros:

• Attractive improvements

• Greater water and chemical resistance

3. Coating and Painting

Application of a coating not only makes the product look better, but it also protects it from the harmful effects of UV rays, moisture, and physical damage.

The most popular types of coating are as follows:

• Primer + Paint – Mainly for decorative parts or prototypes.

• Electroplating – Application of a metallic finish and strengthening of the items at the same time.

• Epoxy Coating – Providing a tough, glossy surface finish.

Tip: For long-lasting outcomes, select the coating that matches your 3D printing material.

How to Select the Right Finish for Your Project

In the case of a 3D printing service, ask these questions when selecting the finish:

1. Functionality – Will the part be subjected to friction, moisture, or stress?

2. Material Type – Finishing for certain materials can only be done with particular finishes.

3. Aesthetics – Do you want a matte, glossy, or coloured surface?

4. Budget and Time – Some finishing options require more cost and time.

For instance, prototypes may simply need sanding, while end parts can benefit from coating or chemical smoothing.

How Online 3D Printing Services Work

When you use online 3d printing services work, your process is uploading the design you have made, selecting the material, and then choosing the finish you want. The service provider is the one that guarantees your part is made, goes through post-processing, and is delivered with accuracy.

Design Tips for Getting the Best Results with MJF 3D Printing

In recent years, MJF 3D printing (Multi Jet Fusion) has emerged as a popular method for creating functional prototyping and usable parts using additive manufacturing processes. Due to its fast turnaround time, high quality, and strong mechanical features, this technology provides cost-effective quality solutions and can deploy much faster. No matter whether you think of yourself as a product designer, an engineer, or just a tinker, enhancing your designs for the MJF 3D printing process may mean for you, lower expenditures, faster production and better results. The purpose of this article is to provide some tips from the experts to contribute to the effective use of mjf 3D printing services.

The Technology of Multi Jet Fusion 3D Printing

Multi jet fusion 3d printing technology fuses layer after layer of powder using fusing and detailing agents with the aid of heat. This technology is particularly known for higher accuracy, isotropic nature and shorter building times than any other powder-based systems such as SLS.

The design choices that are being made influence the quality of the parts that are produced. This ranges from the thickness of the walls to the texture of the surfaces, every single design element can have its repercussions.

Consideration of Wall Thickness and Geometry

It is advisable to have wall thickness of at least 0.6 mm for mechanical components. MJF 3D printing however. Whereas for thinner sections, the wall may crack or deform during its cooling.

Uniform Geometry

• Avoid abrupt cross-sectional changes of the wall thickness

• Uniform geometry is necessary to minimize internal stresses

• Curve instead of make sharp bends

Harness the strength and Precision of Orientation

The placement of the parts in the MJF 3d printing service affects both the strength and the pleasantness of the output.

Suggesting ways to help orient parts:

• Try as much as possible to place flat surfaces on the uppermost part of the print to prevent it from warping

• Vertical build helps in improving mechanical strength

• Dissolvable holes should be provided in evacuated parts

Avoid Design with The Aim of Eliminating Excess Powder

Since the material used in MJF 3D printing is a powder and serves as both the building material and the support,

this is helpful in proper removal of the powder:

• This can be done by incorporating holes of up to 2 mm in hollow objects

• Enclosure of the whole structure should be avoided

• Considering the position where internal pipes will be when placing them

Minimalize the Warping and Curling

Due to the temperature gradients inherent to 3D printing, warping can occur.

In order to achieve this:

• Sharp angles should be replaced by curves

• Stiffen any flat surface by adding ribs or gussets to it

• Where applicable, design for symmetry

Considerations for Finishing in Post Production

Parts created by multi jet fusion can be processed with dying, finishing or even polishing. Consider this in your design:

• Consider coating over allowances made

• Except for parts where aesthetic finish does not matter, smooth the surface in the CAD model

• At least 0.3 mm deep engravings to include logos or any other.

Work with the Right MJF 3D Printing Service

If you need MJF 3D printing services, choose a provider that offers consultation, design review, and quality assurance. A knowledgeable partner can guide you on design changes, material selection, and cost-effective strategies.
