3D printing is not just a hobby. With a 3D printer it is possible to make really practical and useful objects, such as different types of spare parts. If you’re new to 3D printing, you may have a pertinent question: Are there cases where 3D printing an item is actually more affordable than purchasing it?
You need to consider various factors when answering this question. Naturally, the cost of materials will influence the cost of 3D printing something you might otherwise buy in a store. You also need to consider how much electricity a 3D printer consumes when it is operating. Additionally, as with any complex machine, operating a 3D printer will subject it to a certain degree of wear and tear. Frequent use can increase a 3D printer’s maintenance needs and, in the long run, require repairs or replacements. That said, depending on the project, there are cases where 3D printing something instead of buying it can save you money.
When 3D printing an item can be more affordable than buying it
In communities like Reddit’s r/3Dprinting subreddit, users discuss circumstances in which 3D printing something can be more cost-effective than buying it. If someone is looking to save money, users generally recommend focusing on small, lightweight items that can be made with inexpensive filament. For example, one user points out that 3D printing hooks to hang Christmas decorations on cost around $0.07 per hook in terms of material costs, while store-bought hooks cost around $5 for a pack of two.
But what about the cost of running the machine? Again, over time, excessive use of a 3D printer can wear out its components. That said, from a power consumption perspective, the average cost of running most consumer 3D printers is between $0.05 and $0.15 per hour. This means that just running to the store to buy small items like hooks can cost more in travel costs (like gas money) than it would cost to print such items at home.
Other users also point out that sometimes a part you need may not be readily available. If the options are to 3D print a replacement part or place a special order with a retailer offering a hard-to-find item, 3D printing the part will often be less expensive.
Factors influencing the cost of 3D printing
The quality of materials used to create an object can also determine whether purchasing it is more or less expensive than 3D printing it. Sometimes it is technically possible to create a cheaper version of an item using your own 3D printer. However, if you purchase the item, you may be able to get something made from higher quality materials. While its cost may be more than you would spend to 3D print an inferior version at home, its durability may make up for the higher price.
On the other hand, 3D printing gives you the ability to personalize a finished product. This flexibility could be the deciding factor in your decision to print something or buy it.
Of course, your skills and experience will also affect the value of your 3D printing projects. It is therefore wise to familiarize yourself with the common mistakes made by 3D printing beginners, so that you can guard against them.
