Is It Expensive to 3D Print?
It is not expensive to 3D print. What is expensive is the cost of purchasing the printer. The materials are readily available and affordable at a minimal cost.
Despite the fact that there are a lot of expensive 3d printers, you can also find a cheap 3d printer. This could be very useful to Do It Yourself (DIY) category of people.
More so, if you decide to purchase a low-quality 3d printer, it implies that you will use cheap filaments to print. But using a cheap material will give you a low-quality object.
There are various brands of filament and they play a major role in the final look of your printed object. You can get a spool for about 12 USD per kg. But this may not give you the same quality as a spool of 45 USD per kg.
Furthermore, some materials are more expensive than others but one of the cheapest is the ABS. It is commonly used for printing in plastic.
How Much Does ABS Plastic Cost Per Pound?
ABS plastic costs $1.50 per pound. It is inexpensive and readily available. In addition, it can be blended with other materials to produce electrical insulators, pipe fittings, and toys at a minimal cost.
But bear in mind that if you want to print with metal or any other complex material, it will influence the printing costs. Metal filaments are quite expensive, costing hundreds of dollars.
Why Are Metal Filaments Expensive?
Metal filaments are expensive because they are made from raw materials extracted through scientific experiments. These experiments incur equipment and material costs which are usually high. Also, it takes more time to refine them.
This implies that irrespective of the design you are printing, the printing costs will differ based on the materials used.
Factors that Determine 3D Printing Price
The factors that determine 3D printing price include the following:
1. Printing tecnology
2. Size of the printed part
3. Density of the infill
4. Time spent
5. Printing layout
6. Thickness of printed layer
7. Cost of the printer
These factors will be discussed in detail as you read on.
The Printing Technology
In 3d printing, there are different technologies that are employed in the production of 3d printed objects. The technology used will determine the final look of the 3d printed item. It also affects how the item will be printed and the speed at which the printer will operate.
What Are the Types Of 3D Printing Technology?
The types of 3D printing technology are:
1. Fused Deposition Modelling (FDM)
2. Stereolithography (SLA)
3. Digital Light Processing (DLP)
4. Selective Laser Sintering (SLS)
5. Selective Laser Melting (SLM)
6. Electronic Beam Melting (EBM)
7. Laminated Object Manufacturing (LOM)
Fused Deposition Modeling (FDM)
This technology can be used by manufacturers to create prototypes or models of a newly developed product. They function through a process known as extrusion of material. This kind of printer is widely used, and it is the cheapest 3d printer.
What Are the Advantages and Disadvantages Of Fused Deposition Modeling (FDM) Technology?
Advantages of FDM technology are:
1. It is easy to learn
2. It is cost-effective and timesaving
3. It can be used to produce high strength, quality, and waterproof materials.
On the other hand, the disadvantages are:
1. It does not produce an overly neat result
2. It can easily bump up if the extrusion head is not moving
3. It can be affected by temperature fluctuation.
SLA is the first technology in 3D printing. It is used to produce prototypes since it does not take so much time. In addition, the cost of using SLA technology is cheaper when compared with other methods of creating prototypes.
How Does SLA Printing Work?
SLA printing works by using light to cure resin. When resin, a chemical hydrocarbon secreted by plants is exposed to light, it solidifies through a process called photo-polymerization. During this process, it builds 3D objects layer by layer accurately.
SLA is well known due to its accuracy and high level of precision. To manufacturers, SLA technology is more economical.
This explains why it is popular in various fields such as medicine, automotive, aerospace, and entertainment industries. Manufacturers use it to customize goods for their consumers.
Digital Light Processing (DLP)
The DLP is similar to SLA but slightly better than it. It seems to be an improvement on the SLA technology. The digital light processing technology is capable of printing an object with quality resolution. It does this within a short period of time.
How Does Digital Light Processing (DLP) Work?
Digital Light Processing (DLP) works by using micromirrors to reflect color and light on a screen. These micromirrors are very tiny and usually positioned in a semiconductor chip. Consequently, the movement of the micromirrors on the screen produces gray shades used to form 3D objects. They are also called Digital Micromirror Device (DMD).
With this type of 3d printing technology, you do not need to have a lot of materials. The printer will utilize fewer materials and still come up with objects that are flawless.
If you are considering this technology, it will help to reduce the waste of materials. On the other hand, the costs of printing will be drastically reduced.
Selective Laser Sintering (SLS)
What is Selective Laser Sintering (SLS)?
Selective Laser Sintering (SLS) is a 3D printing technology that uses a laser to sinter powdered materials like nylon, plastic, and alumide into a 3D model. Additionally, the laser acts as the source of power and heat that binds the material together to form a solid object.
SLS technology uses metal in powder form. It can also use other types of materials such as ceramics, nylon, glass, silver, steel, aluminum, and much more. The ability to utilize a wide range of material makes SLS very popular.
However, this technology requires a high level of skill and it is quite costly.
Selective Laser Melting (SLM)
SLM technology is used to 3d print parts with very complex geometry. It is not suitable for use in homes due to its very expensive nature. It is popularly used by orthopedics and aerospace industries.
How Does Selective Laser Melting (SLM) Work?
Selective Laser Melting (SLM) works by melting successive layers of metallic powder with a laser. The laser first heats powdered metallic particles until it melts. Then, the machine adds another powdered metal to the melted layer. This process continues till the desired object is formed.
What Is the Difference Between Selective Laser Melting (SLM) and Selective Laser Sintering (SLS)?
Selective Laser Melting (SLM) uses laser to melt powdered metals into 3D objects. It heats the metal until it fuses and melts completely.
On the other hand, Selective Laser Sintering (SLS) uses laser to sinter materials like nylon, glass, ceramics, and other polymers. It heats the materials to a fusing point, without melting them completely.
Electronic Beam Melting (EBM)
What is Electronic Beam Melting (EBM)?
Electronic Beam Melting (EBM) is a 3D printing technology that uses high-velocity electrons to create heat and vaporize a material. These electrons are channelled into a narrow beam and directed to a specific workplace. Also, this technology is majorly used to produce cut outs with precise measurements and metals.
The EBM technology is used to 3d print very dense metallic parts for automotive, dental, medical, and aerospace industries.
What Are Electron Beams?
Electron beams are accelerators of particles. They are emitted by heating a filament. When a filament is heated, voltage draws the electrons from the filament through a vacuum tube and directs them to carry out a specific task. Also, they are used to produce images on television screens, x-rays, and microscopes.
Laminated Object Manufacturing (LOM)
Although this technology isn’t well known, it is one of the fastest and cheapest 3d printing technology. The printing material required here is cheap which makes the technology readily accessible. However, the printed parts will require additional work such as screwing, gluing, or drilling.
How Does Laminated Object Manufacturing (LOM) Work?
Laminated Object Manufacturing (LOM) works by using heat and pressure to fuse plastic or paper together. This process requires overlaying a flat surface with heated plastic, then cutting it into the required shape or size.
It is important to note that the cost of 3d printing is dependent on the technology utilized.
Size of the Printed Part
The cost of printing is dependent on the size of the part to be printed. This is because the size of the printed part determines the amount of printing material to be used.
In essence, printing a large-sized object will consume a large quantity of filament thereby increasing the cost of printing.
Density of Infill
What is Density of Infill?
Density of infill is the amount of materials like plastic, metal, and polycarbonate used inside a print. A print with high density infill implies that the print is highly concentrated with materials. In the same way, a print with low density infill implies that the print is not concentrated with materials.
Before printing, you need to decide on the density of the printed object. This relates to how heavy or solid the object should be made.
If you need an object with a density of about 30 percent, it will be cheap when compared with a density of 70 percent. Hence, the density of infill determines the cost of 3d printing.
Time Spent on 3D Printing
The time it will take the printer to print an object is a very important factor in 3d printing services. This is as a result of the volume of electricity units that will be consumed when the 3d printer is in operation.
A 3d printer uses the same number of electricity units that are used by a refrigerator.
The Printing Layout
When an object is placed to print in a horizontal layout, it consumes lesser time than when placed vertically. This is true because if you place an object vertically, it will print many layers than when turned the other way.
The Thickness of the Printed Layer
The thickness of a printed layer affects the time it will take the printer to get the work done. This does not have a direct effect on the quantity of filament used. Rather, it affects the volume of electricity consumed which in turn, affects the printing services.
What is Layer Thickness In 3D Printing?
Layer thickness in 3D printing is the measurement of the height of each successive layer as they are stacked on each other to form a 3D object. A good layer height for 3D printing is 0.2 millimeters. Also, a layer height is half the size of nozzle printed with.
Cost of the 3D Printer
The aim of every business is to make a profit and have returns on investment (ROI) within the shortest time possible. Hence, a 3d printing service needs to factor in the cost of purchasing a 3d printer.
Well, before you venture into 3d printing business, you need to decide on which printer will suit the volume of 3d printing service you will handle.
How Much Is a 3D Printing Machine?
A 3D printing machine costs $200. It varies in cost, depending on your specific needs. An average 3D printer cost ranges from $200- $10,000.
There are actually very cheap 3d printers but you may end up spending more money on repair and maintenance. However, with expensive machines, there could be less need for frequent maintenance.
So, you need to be smart in making business decisions. If getting a 3d printer cheap, will cost you more in repairs, why don’t you get the expensive brand? This means that the major expense will be on purchasing the machine rather than repairing it later.
Furthermore, if you are still at a loss on how to value your 3d printing service, you can use an online 3d printing cost calculator.
What Is a 3D Printing Cost Calculator?
A 3D printing cost calculator is an online tool used to calculate printing costs and profit. It is available on websites like Omni, 3D addicts, and 3Dprinting pro. Additionally, these websites are highly interactive and user friendly.

How Long Can You Run a 3D Printer?
You can run 3D printing machine for about 30 seconds to one week. However, this is dependent on certain factors like the size of the model, printing technology in use, cost of electricity consumption, as well as time.
3D printers are strong and consume 50 watts per hour, the same watts as with a refrigerator. As a result, they are cheaper and less cost-intensive to run.
Consequently, smaller prints are printed more than larger prints because they reduce the risk of making the printer malfunction due to prolonged usage. Also, in the event of any mistake, a larger print will be ruined. This will cause a greater loss.
Therefore, it is advisable not to run it for prolonged hours without breaks.
