The amount of time it takes to 3D print a part depends on several factors, including the size, height, complexity, and printing technology utilized. This period can range from a mere 30 minutes up to multiple days depending upon the specifics of the job at hand. The variance in time is primarily due to the unique features associated with each task, such as its size, height, level of intricacy, and choice of printing technology.
Printing a simple, small item takes much less time than one that is large and complex. The larger the part and more intricate the design, the longer it will take to print.
This comprehensive guide will supply an enhanced comprehension of the various elements involved in 3D printing (also referred to as additive manufacturing) and how they can have a substantial effect on the length of time it takes for an individual part to be manufactured. By understanding the different variables, users are able to make informed decisions about which materials and methods are best suited for their needs, allowing them to achieve faster print times and improved quality results.
What Are The Variables That Affect 3D Printing Speed?
Type of Materials
Some 3D printing materials require different levels of difficulty to process, with the more challenging materials tending to reduce the speed of the printing process when compared to those that are easier to manage. Depending on the type of material being used, extrusion and bed temperatures will vary, as well as the time taken for it to grip and solidify.
Type of 3D Printer
Generally speaking, some 3D printing machines are more efficient than others, and the ones that are capable of faster production tend to be more expensive. This means that, unfortunately, many of the quickest 3D printers on the market may be too costly for most consumers to purchase.
Size is an important factor to take into account when printing, as larger parts will require more layers in order to complete the printing process. This means that it will take a longer time for the print head to make multiple passes over the model, resulting in an increased duration of the overall printing process.
In addition to the volume of the part, the size and shape of its footprint (X, Y axis) also play a significant role in 3D printing. Larger footprints require more time to print because of the greater distance that must be covered by the print head from its initial starting point. As such, this can prolong the overall printing process and increase the amount of material used for production.
Aside from the size of the component, height is another factor that needs to be taken into consideration. As the 3D printed parts are constructed layer-by-layer, those with greater heights necessitate more passes in order to complete them, thus significantly increasing their production time. Consequently, when calculating the printing time for a particular part, it is important to consider its dimensions and height.
For instance, a part with dimensions of 4x4x4 will require less time to print than one with measurements of 3x3x7, even though they have the same volume. This is because the larger part has more surface area that needs to be printed, and consequently takes longer to complete.
Geometry / Complexity
The intricacy of the geometry of a part is an important factor in determining the amount of time it will take to 3D-print that part. Indeed, the more complex or detailed its geometry is, the longer it will take for a printer to fabricate it. Therefore, when considering how long it might take to create an object through 3D printing, one should keep in mind its underlying geometric complexity.
If a part has multiple intricate layers, then the 3D printing head must construct and define the boundaries of these components before it can fill in each layer. The amount of time needed to build such a structure is dependent on the type of 3D printing technology being used; some systems are capable of rapidly depositing more complex geometries than others, thus accelerating production times.
Type of Printing
The exact type of 3D printing used has an effect on the duration it takes to complete a print job; some techniques are known to be slower than other methods. Generally, 3D printing processes can be divided into two main categories: paintbrush and paint roller style printing. Paintbrush-type 3D printing is often considered to be slower than paint-roller-type printing due to the fact that it needs more time for each layer of material to dry before another layer is added, whereas, with the latter, layers can be applied in quick succession.
The difference between the paintbrush and paint roller methods lies in how they extrude material across the build tray. The print head is used to do this, with paint brush type printing coming from a single point as it moves over, but using a number of points of extrusion when using paint roller style.
The 3D part’s inner construction is referred to as the infill, which influences the printing speed. This is due to more complex patterns requiring more time in order to render them, as well as a higher density equaling more time while simultaneously boosting the strength and durability of the finalized product.
The amount of components being generated directly influences the duration needed to finish a 3D printing task. In most cases, producing multiple copies of an item tends to make the process faster, as you no longer need to arrange the 3D printer tooling and materials for each part after the first one has been printed. Therefore, if there is a requirement for multiple parts at once, it is more effective in terms of time and effort.
The ultimate variable that can influence printing speeds is post-processing. This stage necessitates the washing, cleansing, and drying of 3D-printed parts. Depending on the size and shape of the objects, every technology has its own post-processing parameters, with times varying accordingly. It is, therefore, important to consider these factors when estimating how long it will take to complete a 3D printing job.
Quality / Layer Height
The quality of a 3D printed part is inextricably linked to the layer height, which typically lies within the range of 100 to 500 microns (0.1-0.5mm). This is because thinner layers provide a smoother finish and improved quality; however, this comes at the cost of longer production time. Therefore, managing expectations regarding print times is important if you are looking for higher-quality prints.
