Factors Influencing Printing Cost
Build Plate Size
The build plate size also affects 3D printing costs. Build plate refers to the maximum dimensions the printer can create. Larger build plates typically result in higher costs due to increased material usage, longer print times, and added print job complexity. Smaller parts often use less material and can be printed using more cost-efficient methods.
Support Structures
Another major component influencing the cost of 3D printing is the usage of support structures. These structures help to build complex geometries and prevent recurring issues due to overhangs or steep angles. Depending on the 3D printing process, the design of support structures can vary. Support material adds to the overall material cost and increases the time needed for post-processing to remove and refine the printed object. Efficient use of support structures will help reduce the overall cost of 3D-printed parts.
Print Quality
The print quality, determined by layer height and printing speed, also affects the cost of a 3D print. Higher resolution prints, achieved through lower layer heights, lead to smoother surfaces but increase the number of layers required, resulting in extended printing times and higher material costs. In contrast, faster printing speeds can reduce costs but may lead to lower-quality outputs. Balancing print quality and cost requires understanding the specific requirements of individual projects, thereby optimizing printing costs for each workpiece.
Post-Processing Requirements
3D printing post-processing is an essential step in producing high-quality products. Several steps are involved in post-processing to improve the appearance and functionality of the printed part. This section will cover two primary post-processing techniques: Support Removal and Surface Finishing.
Support Removal
A support structure is often required when printing a 3D-printed object with complex geometries or overhangs. These supports need to be removed after the print is complete. Different support removal methods exist, depending on the printing material and technology used.
For Fused Deposition Modeling (FDM) prints, supports can often be broken away manually. However, in some cases, tools such as pliers, tweezers, or a scalpel may be required for proper removal. Be careful during this process, as excessive force could damage the printed part.
Stereolithography (SLA) or Digital Light Processing (DLP) techniques make the support structures more intricate and challenging to remove. In such cases, the part should be cleaned in an isopropyl alcohol solution before support removal. This helps soften the supports, making them easier to detach and removing any excess resin from the model's surface.
Surface Finishing
The surface of 3D printed parts may require finishing to obtain the desired visual appearance, feel, or mechanical properties. There are several surface finishing techniques.
Sanding: Sandpaper with varying grit sizes can smooth layer lines and rough surfaces. This method is commonly employed for FDM, SLA, and DLP prints.
Vapor smoothing: This involves exposing ABS prints to acetone vapor, dissolving the material's outer layer, and producing a smooth, glossy surface. This process can improve both the appearance and strength of the printed part.
Chemical baths: Some materials can be bathed in specific chemicals to smoothen their surfaces. For instance, isopropyl alcohol can smoothen SLA or DLP prints.
Painting: This method may be applied to various materials, including FDM, SLA, and SLS prints. Painting not only enhances aesthetics but can sometimes improve the part's durability.
Proper post-processing is crucial for achieving desired results from 3D-printed parts. Careful consideration of support removal and surface finishing techniques can significantly improve the final product's appearance, feel, and functionality.
