Estimating the Cost of 3D Printing: A Complete Guide
Due to its simplicity, accuracy, precision, and adaptability for producing objects with complicated designs, 3D printing is widely used by both enterprises and individuals. Many people use the procedure for do-it-yourself projects or contract out to 3D printing services because it works for commercial and industrial-grade products. Whichever solution you choose, you should think about how much a 3D printing service would cost before getting started.
A variety of factors cause the variance in prices, and this article will outline those that have an impact on the cost of 3D printing services as well as how to estimate and lower the price of 3D printed parts. Rapid prototyping is a subset of additive manufacturing, in which 3D printing is the same.
What Determines 3D Printing Service Cost?
Choosing the best 3D printing service is a major financial choice. It is crucial to understand several elements that can affect how much money you spend on printing or exporting your project. The key factors to take into account in the cost and 3D printing relationship are listed below.
How to Calculate the 3D Print Cost?
The following are standard methods to determine the cost of your 3D printing project:
- Specify the type of material for your 3D printer and obtain a kilogram price. Find out its density as well.
- Determine the model's volume for 3D printing. For greater accuracy, use your design software.
- Multiply the volume per material density of your model to obtain its mass.
- Multiply the mass that was acquired by the cost of the material per kilogram. Your 3D print material cost is shown in the output. Don't forget to include labor expenses like power and design time.
Cost of Printing a Prototype
The cost for a straightforward prototype weighing 200 grams is: Given that the filament costs $25 per kilogram when converted to grams, $25/1000 g equals $0.025/g.
Consequently, the price to produce this 200g of filament would be 200 x 0.025, or $5. This is not always the case, though, as prototypes may weigh just 20g. They could also be enormous things, weighing many kilograms.
Type of Material
The materials you select have an impact on the price of 3D printing. There are many options, so we'll concentrate on thermoplastics and resin, which are the most common.
Filament and Powder
Even if 3D printing is new to you, you've probably heard of "ABS" or "PLA." This is because these two types of 3D printing materials are the most common. Due to their low cost, hobbyists adore these thermoplastics. The price per kg of these filaments ranges from $20 to $70.
Although inexpensive, producing a high-quality 3D print from them isn't easy. Hours of post-processing will be required to achieve a nice finish on these prints. Additionally, utilizing this kind of material to print complicated 3D models is almost impossible.
High-End Materials
The price of 3D printing services typically rises when you utilize expensive materials. High-end materials are more costly since they are more challenging to find and less common. For instance, alloy steel, cobalt, titanium, aluminum, and nickel are exceedingly expensive to work with. This is because certain technologies are required, such as DMLS, which was demonstrated to be costly in the previous section.
Resin
Resin is one of the greatest 3D printing material currently available. It may be used for practically any complicated project and will produce the highest-quality 3D prints. However, resin material might be fairly expensive. The typical price of standard resin is $50 per liter, and the price of some resin components can reach $300 per liter. Fortunately, 3D printing businesses frequently have access to discounted costs for this kind of substance.
Print Time
Print speed and time is a fundamental variable that significantly affects how much a 3D print costs. Businesses that offer 3D printing make a set amount per hour that the machine is in use. Every 3D printing company has its hourly rate. If a company spent $2,000 for a 3D printer with a lifespan of 2,000 print hours, they might bill customers $1 an hour. (Remember that this example is purely hypothetical and is only used to illustrate a point.)
Size and Complexity
A 3D model is necessary for designing 3D prints since it gives the critical information required for the production process, resulting in a precise 3D image. It is simpler to calculate the price of a 3D print or 3D-printed service after you have the 3D model.
The final cost of the 3D print depends on the model's size and complexity. The price will be impacted by the necessity for precise and detailed 3D printing for complex designs. Preventing capital and time waste is made possible by being aware of the size and complexity of the 3D model.
Post Process
Most people are unaware that 3D printing is a lengthy procedure. Place your file there, print it, and it's done. (We assume it was.) Before considering the 3D-printed objects usable, they must be dried, cleaned, and polished. That is if the provider of 3D printing services is concerned about the caliber of their output.
1. Polish
Avoid wasting any time on filaments. We don't want to make you go through that hell after spending hours taking down support. The time you will spend refinishing these prints will cost you a lot of money if you value your time. The quality would not be on par with resin even then.
2. Electroplating
Specifically, chosen metals, such as gold or silver, are electrochemically coated onto the 3D printouts in this process. An electrolyte is applied to both the metal and the 3D print, which act as the cathode and anode, respectively. Metal ions are deposited on the 3D model as electricity flows through it. 3D images can be strengthened and given a more appealing finish with electroplating. But because of the machinery and the metal plating, the process is costly.
3. Coating With Epoxy
To increase their strength and seal the porous area of the prints, the epoxy coating is recommended, including coating the 3D images with epoxy coating and a hardener. It is typically a pricey and effective preventive measure. Depending on the epoxy coating you use and the skill of the coater, the process will cost you a certain amount of money.
Maintenance Cost
3D printers will produce prints of the highest quality, but without upkeep, their functionality and print efficiency will suffer. A 3D printer requires appropriate maintenance, much as many other machines. But there is a price to pay for this.
The cost of cleaning and replacing 3D printer parts is included in the maintenance charges. This may cost a few hundred dollars, depending on the components and the degree of sophistication of the 3D printer.
The upkeep costs, for an FDM printer, for instance, run from $200 to $500. The maintenance charges will go up for those who hire specialists because they will also be charged by the "expertise."
Profit Margin
The cost of 3D printing must be added to a profit margin for 3D printing businesses to remain profitable. A 3D printing company's profit margins might range from 50% to 90% of the cost of the materials. For the sake of simplicity, we're using material cost as our foundation. But once you start factoring in labor and overhead expenditures, profitability is substantially smaller.
If the price of 3D printing is less than a particular amount, a base price (or minimum fee) is added. It would be absurd for a business to 3D print anything for you for a $3 print. Even in a 3D printing service that is highly automated, a workforce is still required. Either increase the quantity or pay the base fee, which ranges between $30 and $90.
Advanced Parameters
The fundamental parameters are those listed above. The additional running costs (such as energy and internet) and the printer's failure rate are two more sophisticated parameters that improve the price's accuracy.
Why are Services for 3D Printing so Expensive?
The cost of 3D printing services is high because we must factor in the previously mentioned expenses for labor, post-processing, and overhead. The industrial 3D printers they employ, which cost at least $100,000 and possibly even more, must also be considered. Additionally, they must add profitability on top of that expense. It’s less complicated for resin. We can use a sandblaster or a hand polisher to finish the pieces once they have been UV-cured.
How Might Printing Costs be Reduced?
Machine time and material costs affect how much 3D printed components and services charge. You should balance these aspects if you want to lower the price of 3D printing. Here are a few practical and technical techniques to reduce the cost of 3D printing.
• Use less expensive materials.
• Pick the proper procedure.
• Reduce infill, remove support, and hollow objects to conserve printing material.
• Choose a suitable conclusion and resolution.
