3D Printing Cost Factors: A Comprehensive Overview
From the outlying perspective, 3D Printing might seem an expensive route to take for your manufacturing and production needs. But before you shelve it off as an impractical option, it's worth taking a deep dive into specific elements that shape the total cost of 3D Printing services.
The Object Material and the Printing Method
Not all 3D prints use the same raw material or follow the same method. The cost of your print can significantly differ based on the materials used like Polylactic Acid (PLA), Acrylonitrile Butadiene Styrene (ABS), Nylon, and others. The decision won't just affect your expenses but also the quality and durability of your finished objects.
PLA is the most affordable of the lot, with costs averaging around $25 per kilogram. The ABS comes next, averaging around $50 per kilogram, while the cost of Nylon could reach upto $250 per kilogram, making it the most expensive.
Your choice of 3D printing method, either FDM (Fused Deposition Modeling), SLA (Stereolithography), or SLS (Selective Laser Sintering), will also determine your total 3D printing service cost.
The Intricacy of Your Designs
Generally, more complex objects consume more material and production time, raising the overall costs. Unnecessary overhangs and supports in the design can add to material consumption and the required post-processing time, further increasing the total cost.
The Machine Time
The printing speed, which may vary from printer to printer, is an important determinant of cost in 3D printing services. The more time a machine spends on completing a print, the higher the cost will be due to increased power consumption.
Post-Processing Steps
Many people overlook this step when counting 3D printing costs. Every print needs some finishing touch like sanding, painting, or polishing, which directly affects time and cost.
Now that we've incorporated an understanding of the cost elements, let's delve into a comparative cost analysis looking at relevant examples to give you a better picture.
Cost Example 1: Producing a Pen Holder
Let's say we're using the FDM method to print a pen holder, an object of medium complexity. We're using PLA, which costs $25 per kilogram. The pen holder may weigh around 120 grams, costing roughly $3 in materials.
The machine time could take approximately 2 hours, considering the complexity and size of the design. With the cost of power and overhead calculated at around $0.15 per hour, the machine time cost would be $0.30.
If the post-processing takes about 30 minutes, it could add another $0.08 to the calculation.
Cost Example 2: Developing a Custom Drone Body
In this example, we're using ABS via the SLS method to create a custom drone chassis. ABS costs $50 per kilogram, and the drone chassis may weigh about 800 grams, costing us $40 in raw material.
The SLS method can take about 4 hours for the full print, consuming $0.60 in power and overhead costs. Given the complexity of the drone body, post-processing might take 2 hours, costing an additional $0.30.
From these examples, it's apparent that the cost can differ quite significantly based on many variables. Therefore, considering and calculating these factors beforehand is highly recommended for efficient cost planning when looking into 3D printing services.
With a better understanding of the cost factors, anyone can optimize their 3D printing projects to suit their budget without compromising on quality. Anyone venturing into the world of 3D printing should therefore look into these intricacies to ensure efficient and cost-effective results.
