Electricity cost of running a 3d printer

How Much Electric Power Does a 3D Printer Use? – 3D Printerly

Besides the cost of the 3D printer itself and the material to actually print out objects, there’s another thing creeps into people’s minds. Just how much electric is this thing using?!

It is a fair question. As fun as it is to 3D print our own objects, we want it to be as cost effective as possible. In this post I’m going to identify just how much power these 3D printers are using up and ways to manage it. 

The average 3D printer with a hotend at 205°C and heated bed at 60°C draws an average power of 70 watts. For a 10-hour print, this would use 0.7kWh which is around 9 cents. The electric power your 3D printer uses depends mainly on the size of your printer and the temperature of the heated bed and nozzle.

There’s some more pretty useful information that you’ll want to know in the rest of this article, so keep on reading to get the proper knowledge on electricity with 3D printers.

Determine Power Use by 3D Printer Specifications

Your 3D printer specifications for the power source and maximum/minimum power ratings are the answers you need so you know the limits of power consumption.

As an example, if a printer has a 30A 12V power source, it will have a maximum Watt of 360 (30*12=360), but the printer won’t always run at the upper limit. These maximums will kick in when heating up the necessary parts to start the printing process but will fall much lower as the printing is happening. 

A great low-power 3D printer has to be the Ender 3 (Amazon), it’s an all-round popular machine that is perfect for beginners with quality that matches the most premium printers out there. You’ll see from the glowing reviews just how good it is!

Jason King from 3DPrintHQ used the MakerBot Replicator 2 printer and found that the energy costs were only $0. 05 for a 5-hour print. 3D printing only used 50 watts per hour, which is comparable to an HP Laser Jet printer on stand-by, not even while printing or 1 use of your toaster.  

Low Relative Cost of Power

When looking at the overall cost of 3D printing, power costs are something that is relatively very low and not something to worry about. Some printers will of course be more efficient than others, but not at such a point that it’s a big determining factor when choosing a printer over another. 

Now there are slight differences in how much power a 3D printer is using depending on what the printer is actually doing. When the printer is preheating to the set temperature, if the print bed is relatively large it will use slightly more power than when printing.  

The first real use of electric power when a 3D printer is turned on is the heating of the print bed, then comes in the nozzle is heated to the temperature for the specific material. While printing, you will get spikes in the power usage depending on if the heated platform is on to maintain the ideal temperature.  

From what I’ve read around, it looks like the average 3D printer consumers as much electric as your standard fridge. 

What Affects How Much Power is Used?

Strathprints done a test to compare the power consumption between four different 3D printers and confirmed a few things. The lower the layer thickness of the material, the longer a print will take therefore leading to a higher power consumption overall.

If you can speed up your prints you’ll be using less power overall so check out my post 8 Ways to Speed Up Your 3D Printer Without Losing Quality.

When the heating efficiency of a print bed or hot end is good, it will result in less power being used due to not having to constantly keep the temperatures hot as much.  

The video below shows the wide differences in how much electricity a 3D printer will use when incorporating the heated bed.

A good idea to lower how much heating your bed has to do is to use an Ashata Heat Insulator Mat. It has great thermal conductivity and greatly reduces heat and cooling loss of your heated bed.

The MakerBot-Replicator 2X had a baseline of between 40-75 watts to power the controller and motor, but peaked to 180 watts when heat was needed. The hotter the necessary print bed temperature, the more frequent the 3D printer drew power shown by fluctuations in the watt meter used.  

The test showed that there is quite a variance between the power consumption of 3D printers. So, it can be concluded that 3D printers don’t consume a similar level of power and it really does depend on many factors.   

The set-up parameters of your 3D printer will have a pronounced influence on the overall power consumption. It is important to be familiar with the process of 3D printing so you can print high quality products at lower electricity levels. 

If you want to take an extra step, get yourself an enclosure. A great one is the Sovol Warm Enclosure for Ender 3D Printers. It’s pretty pricey, but it will last you years and usually results in better prints.

How Do I Lower Electricity Costs With a 3D Printer?

• Use a smaller 3D printer
• Use 3D printing materials that don’t require a heated bed or high nozzle temperatures (PLA)
• Implement 3D printer settings that make 3D prints quicker
• Change to a larger nozzle so your prints don’t last as long
• Make sure you are 3D printing in a fairly warm environment

When it comes down to lowering power costs with your 3D printer, it boils down to finding ways that speed up your 3D prints and doesn’t require as much heating.

The simple things you can do to speed up prints is to use a bigger nozzle, use less infill, print less often, or printing more things at once rather than doing them separately.

Most of the electricity use comes from the heating elements, so focus on reducing the heat and you’ll be able to save more on power.

This isn’t usually a problem since the associated costs aren’t relatively high. You’re definitely going to be using more money on the filament itself than you ever would with the electricity.

How Much Power Does a 3D Printer Use?

How Much Electric Does an Ender 3 Use?

One Ender 3 user who had their 3D printer running for 4 hours only used around 0.5kWh (kilowatt-hour), which consisted of heating up twice (using 280 watts per). When you calculate this on a per hour basis, we can 0.12kWh per hour of using an Ender 3.

People like to know how much power would cost if their Ender 3 was running for a full day, so let’s take a 24-hour period.

24 * 0. 12kWh = 2.88kWh

The average cost of one kilowatt-hour across the US is 12 cents according to NPR, so a full 24 hours of running an Ender 3 would cost $0.35. If you ran your Ender 3 24 hours for the whole month, it would cost you around $11.

The Ender 3 has a 360W power supply (24V DC at 15A.

• Heated Bed – 220W
• 4 Stepper Motors – 16W
• Fans, Mainboard, LCD – 1-2W

After these parts, you should have a spare 60-70 Watts in spare capacity, which allows you to add extra things.

A basic set of 5050 LED lights connected to your 3D printer can be around 20W.

Can You Get Electric Shocks From a 3D Printer?

Now that you know 3D printers don’t actually use that much electricity, you might be wondering whether they are still capable of giving you electric shock. This is a valid question and the answer is pretty simple.

A 3D printer can give you electric shock if you don’t handle it properly, but with proper use, you will be safe from getting an electric shock.

One 3D printer user actually received an electric shock from the power supply, but it was through misuse. After setting up their 3D printer, they used an EU to UK adapter and set the voltage to 230V.

It would have been a better idea to purchase or get the seller to send them a UK plug rather than use an adapter. This could have happened due to poor grounding, because a small current can flow through the connections from the live wire.

Luckily it was just a harmless tingle/shock! You shouldn’t use electronics which are not grounded when they are  supposed to be.

How Can I Measure My Actual Electricity Use?

When it comes to electricity use, there really isn’t a perfect measurement we can give you because there are many differences and variables. The best thing you can do to really know how much power you are using is to measure it yourself, rather than us guess for you.

You can purchase a power meter which has an in-built power usage monitor. High-end ones can even calculate the cost of your power usage, so it can easily answer your question.

There are plenty of electricity monitors out there, so I done some research and found one that works very well for most people.

The Poniie PN1500 Portable Electricity Monitor is going to be your best choice. Not only is it officially ‘Amazon’s Choice’ at time of writing, but it is the highest rated out of all the monitors at 4.8/5.

Here’s what’s good about this power monitor:

• Very easy to use, with access to different power parameters
• High-precision current sensor
• Backlight & memory with large digital numbers for easy viewing
• Ability to start detection at just 0.20W so you can monitor almost anything
• 1 full year warranty

You can easily monitor electrical use in real time and it has multiple uses which can allow you to save on future electricity bills. Whether you test other appliances like an old refrigerator or other power-wasting appliances.

Range Of Electricity Use For A 3D Printer

An example of the minimum and maximum levels of power a 3D printer can use is the MakerBot Replicator+, which according to the specs has between 100-240 volts and 0. 43-0.76 amps. To convert this, we simply need to multiply the lower ends and higher ends to get our limits.  

100 volts * 0.43 amps = 43 watts 

240 volts * 0.76 amps = 182.4 watts 

So, the power can range anywhere between 43 and 182.4 watts. 

From the watts, we convert this to kilowatts per hour (KwH) by dividing the watts by 1000 then multiplying the number of hours in use. For example, if you had a print that lasted 5 hours the calculation would be: 

43 watts/1000 = 0.043 Kw * 5 hours = 0.215 KwH for the lower limit.  

182.4 watts/1000 = 0.182 Kw * 5 = 0.912 KwH for the upper limit. 

Just as an example, if we take the happy middle for these two power measurements, we’d have 0.56 KWh, costing you only 5-6c in electricity per hour. So now you have a bit of a gauge in just how much electric is used in 3D printing, which isn’t much at all but it can slowly build up over time.

Compared to the actual cost of the 3D printer, the filament materials and other tools and equipment the electric power required for 3D printers is something that you shouldn’t have to worry about.

When we’re talking about sizeable professional printers, then the power costs could be something to take into consideration, but for your standard domestic 3D printer it is very low cost. 

If you love great quality 3D prints, you’ll love the AMX3d Pro Grade 3D Printer Tool Kit from Amazon. It is a staple set of 3D printing tools that gives you everything you need to remove, clean & finish your 3D prints.

It gives you the ability to:

How much will my electricity bill be?

Feb 16, 2022

The 2nd highest expense regarding 3D printer power consumption is electricity, preceded only by the cost of filament. The cost of electricity for your 3D printer varies depending on the printer model, printing time and material used.

For any manufacturing company, it is essential to know your real cost per part. Subsequently, when using a 3D printer it’s important to calculate the following variables:

• Amortization of the printer 
• Filament used
• Operator cost
• Software programs, such as the BCN3D Cloud Teams 
• 3D printer power consumption

 On this occasion, we’re going to focus on the latter.

If we know the cost of energy for 1 hour, we can easily calculate how much each type of part consumes according to the printing time.

Let’s take for example the BCN3D Epsilon W50 printer, which has a maximum consumption of 840W per hour. Let’s also imagine that we are printing with both extruders and with PAHT CF15, a filament that needs to be melted at a higher temperature of 280°C, so we are consuming as many watts as possible. If we take into account that the average price per kWh in 2021 in Spain was 0.253 €, the maximum amount you’ll spend with an Epsilon W50 is 0.21 €/h. 

On the other hand, if we were to print in an off-peak hour (at €0.07 kWh), one hour of printing would cost us a maximum of €0.06 per hour. Keep in mind that these prices would be if the printer were consuming the maximum possible amount of energy. So the electrical cost for a normal print on an Epsilon W50 can be less than 0.03 € / h – very affordable!

We have just seen the maximum price you can pay for 1 hour of printing on an Epsilon W50…but let’s see what else affects the consumption of a 3D printer:

• The printer model: There are other 3D printers that consume much more than those of BCN3D, reaching 1700W, so having a machine with low energy efficiency could double the electricity costs, at around 0.4 € per hour.
• The filament: Each material needs to be melted at a different temperature, for example, PLA melts at 200°C and ABS at 240°C. Therefore, printing with PLA instead of ABS will reduce energy consumption.

• Print speed: While printing faster will significantly reduce the overall energy cost of the part, it will increase the consumption per hour, as the printheads will need more electricity in order to go faster.

By following the recommendations below, you could reduce the cost of energy per part by 80%, thanks to IDEX technology and the software implemented by BCN3D:

1. Printing in Duplication/Mirror mode: Printing with two extruders at the same time not only reduces printing time by half, but also significantly reduces energy consumption by using the same printing surface, the same bar moving in the Y direction (the X-axis) and the same electronics.
2. Printing with the recommended profiles: When you use our BCN3D Stratos slicer, you will see that each material has different configurations. These configurations have been studied and tested in our laboratory so that the figures come out perfectly, quickly and efficiently.
3. Printing during “off-peak hours” (Spain only): If you only have to print one part and you don’t need it immediately, you can set the printing to start at an “off-peak hour” using the free BCN3D Cloud tool.

In conclusion, your 3D printer power consumption is a cost to be taken into account, but it’s not so high as to be an impediment to the use of this technology. In fact, the company TensaBelt uses “in-house” 3D printers instead of using other traditional methods for faster and more efficient prototyping. However, from BCN3D we try to further reduce these costs by using very efficient printers, with IDEX technology and the BCN3D Cloud.  

Now that you know how to minimize these costs, it’s time to start printing! Learn more about the Epsilon W50, Smart Cabinet and the rest of our 3D printers on our website.

How much electricity does a 3D printer consume?

While 3D printing is certainly a fun hobby, there's no doubt that it can also get quite expensive. Apart from the cost of the printer and filaments, you could easily spend a few hundred dollars just to get started. Another recurring cost that we should not ignore is the cost of electricity consumed by a 3D printer.

Whether you're 3D printing for fun or business, the money you spend on electricity is what you need. keep in mind. How much electricity does a 3D printer use and what can you do to reduce your energy bills?

12. Final Thoughts

Step One: Check Your Printer's Power Rating

Like any electrical device, your 3D printer must be rated. For example, a 3D printer that requires 30A 12V consumes up to 360W of power (power = current x voltage). This is a very high figure, but only because it is the maximum power that this particular 3D printer can draw.

There can be a very significant difference in power consumption if you print at high temperatures. , high speed settings or heated beds. However, between different models, you can expect printers with larger platforms to use more power, as well as printers that can print at higher temperatures.

What factors affect how much energy 3D printing consumes?

If you're interested in the exact amount of power your 3D printer requires, then the best way is to use a power consumption monitoring tool. These tools act as an interface between your 3D printer and an electrical outlet, giving you an accurate measurement of the volts, amps, and power your 3D printer draws. A good example is Kill A Watt Electricity Usage Monitor by P3.

It would be impossible to isolate any particular part of the 3D printing process and test how it affects the power consumption of the printer. Instead, we can sum up these factors and infer how much electricity they consume.

Heating at the hot end

One of the most energy intensive drain parts of a 3D printer is the hot end, specifically the part of the nozzle that melts the filament. How much energy this process consumes depends on the temperature you set as well as the type of filament you are working with. If you're working with a lot of high temperature fibers like nylon or ABS, then you're probably using a lot of electricity for just that part.

Print bed heating

The print bed temperature depends on the nozzle temperature. This is a measure that improves adhesion to the layer and prevents warping, which is one of the constant problems when working with high temperature fibers.

There are two factors to consider when evaluating the energy consumption of a heater. bed – temperature setting and bed size. The temperature also depends on the type of filament you are printing with. The size of the bed depends on your 3D printer. The larger the bed, the more energy will be required to maintain the set temperature.

Heat loss

3D printer components can reach temperatures above 200°C. They must also remain at this temperature, so any heat loss to the environment must be compensated by the heating element. This is another issue for high temperature 3D printing as a hotter nozzle and print bed will inevitably have higher heat loss. If there is a way to minimize heat loss, you can save a lot on your energy costs.

Stepper Motors

There are two important sets of stepper motors in one 3D printer: those that drive the extruder gears and those that drive the movement of the nozzle. While these motors are very small and draw little power, they also need to be constantly running for the hours needed to complete a single 3D printing project.

Control Board

The control board or "brain" of a 3D printer consists of several electrical components that help control the printer's temperature, nozzle placement, extruder gears, and various other trivial tasks. Despite the importance of this feature, the control board does not actually consume much power.

The conclusion that we can draw from this little exercise is that most of the energy consumed by a 3D printer goes towards heating the nozzle and the print bed. While not surprising, this fact also gives us insight into how we can reduce the power consumption of our 3D printing projects.

Comparison of power consumption of various 3D printer models

Since it is impossible to determine the exact power consumption of a 3D printer without specifying the model, we will look at how much power consumption of various 3D printer models and how this affects costs.

Let's start with the Monoprice Mini Delta, a very small and inexpensive Delta type device. A 3D printer that has proven to be quite popular among beginners. Among its distinguishing features are a small build platform and a print head driven by three stepper motors. The Monoprice Mini Delta reportedly only consumes up to 45W during bed and nozzle preheating. Power consumption during printing increases slightly to 60W, probably due to the action of the stepper motors.

To provide contrast, let's look at the power consumption of Flashforge Creator Pro. This is a much more expensive 3D printer with a larger print bed, a rigid metal frame, and a built-in housing. Preheating the large print bed required a staggering 300W of power, while the nozzle required slightly less than 280W. The case proved to be very useful in reducing heat loss and stabilizing the printer's power to 250W during printing.

The two 3D printers we referenced here give us a useful range for how much power models of varying complexity can consume, from 60W to 250W when printed. In terms of kWh, this range corresponds to 0.07–0.24 kWh.

This also allows us to compare the power consumption of 3D printers with other devices we have in the house. For example, a typical desktop computer consumes about 1.05 kWh, which is more than four times the power consumption of Flashforge Creator Pro.

Based on electricity tariff data from April 2020, the average US consumer pays 13.31 cents per kWh. This means that you will pay approximately 3.2 cents for every hour you use Flashforge Creator Pro. The numbers for the Monoprice Mini Delta are even more pleasantly surprising - you pay less than 1 cent for every hour of use.

These numbers are likely to come as a relief to 3D printing enthusiasts, especially those who leave their printers running for hours on end. While this isn't an excuse for wasting electricity, it's still nice to know that you haven't been hit hard on your running costs just because you got into 3D printing.

Cost Saving Tips 3D Printer Power Consumption

Although you've come to terms with the fact that you're unlikely to add a huge amount to your energy bill just because you use a 3D printer, many of you probably we still appreciate any advice on how to reduce power consumption.

1. Use the Printer with the

Enclosure As our analysis of Flashforge Creator Pro has shown, having a platen enclosure can significantly reduce the power consumption of a 3D printer during the printing process. This becomes even more pronounced if you are printing with a filament that requires high temperatures for both the nozzle and the print bed. If you're using an inexpensive printer without a built-in case, you can simply make your own using a couple of plastic sheets and wood frames. There are many tutorials on the internet for DIY 3D printer cases.

2. Reduce print time

Time is a factor we haven't talked about much, but it's certainly one of the most important when determining how much power a 3D printer consumes. If you can reduce the print time of your project, you can significantly reduce your energy costs.

There are several ways to achieve this goal, but there are two that are particularly effective: increasing print speed and printing with thicker layers. Obviously, this is not advice that can be taken in a vacuum. When making these adjustments, you need to consider other factors such as print temperature, filament type, and the quality level of the finished product..

3. Print with high temperature fibers only when necessary

Experimenting with different types of fiber materials is a natural part of 3D printing, but using those that require very high print temperatures can be quite expensive in the long run. . This requires not only more heat in the nozzle, but also a hotter print bed. The difference between 30 and 40°C may not seem like much, but every little thing counts – at least depending on which point of view you take.

Your 3D printer is unnecessary, then you can stick with low temperature fibers like PLA if you're printing just for fun. PLA not only saves energy but is also a more environmentally friendly choice due to its biodegradable nature.

Closing Thoughts

Consider how much power each of our electrical devices we consume on a regular basis is only part of being a responsible consumer. The same principle applies to 3D printers. As 3D printing is quickly becoming a hobby for more and more people, now is the perfect time to be more aware of how much power 3D printers use.

It's nice to know how energy efficient 3D printers are, especially when compared to the computers and TVs we usually have at home. However, this is no excuse for not making any effort to reduce the power consumption of our 3D printers. When used responsibly, we can reduce energy costs by fulfilling our responsibilities as responsible citizens.

Attention! Never leave 3D printers unattended. They can pose a fire safety hazard.
