3D printing, a technology that once seemed to be a thing of science fiction, has now become a reality. Whether you’re a hobbyist or someone considering diving into the world of 3D printing, this guide is meant to answer some of the most frequently asked questions on the subject and help you make informed decisions.

Is it Expensive to Own a 3D Printer?

When contemplating the costs of owning a 3D printer, we should consider not only the upfront cost of the machine but also the ongoing expenses for materials and maintenance. For example, the Bambu X1 Carbon is a popular model among 3D enthusiasts, offering excellent features at a relatively affordable price point.

The Bambu X1 Carbon is an example of a 3D printer that provides value for your investment. However, costs can widely vary depending on the complexity and capacity of the printer.

How Much Should I Pay for a 3D Printer?

The price range for 3D printers is vast. On the lower end, basic hobbyist models such as the Creality Ender 5 S1 can cost a few hundred dollars. These entry-level printers are ideal for beginners and hobbyists interested in exploring 3D printing without making a significant financial commitment.

Conversely, industrial-grade 3D printers with advanced features and capabilities can cost thousands of dollars. However, a high price doesn’t necessarily mean it’s the best choice for everyone. It’s essential to consider your specific needs, budget, and skill level when determining how much to invest in a 3D printer.

What Type of 3D Printer is Best?

The “best” 3D printer largely depends on your individual needs and intended use. Several types of 3D printers are available, each with its pros and cons.

Fused Deposition Modeling (FDM) printers are the most common type, ideal for beginners and hobbyists due to their affordability and ease of use. FDM printers create objects by extruding melted material layer by layer. They can print with a variety of materials, including PLA and ABS plastics.

On the other hand, Stereolithography (SLA) printers use a light source to solidify a resin, providing a higher level of detail than FDM printers. They’re generally more expensive and require more maintenance, but they’re excellent for applications requiring high precision and detail.

What is the Best 3D Printer of All Time?

Determining the “best” 3D printer of all time is subjective, as it largely depends on individual needs and preferences. However, some models have gained recognition for their performance, durability, and value for money. The best 3D printers for under $500 provides a good starting point to understand which printers have been well-received by the community.

What is the Strongest Shape to 3D Print?

When it comes to strength in 3D printing, the geometrical design plays a crucial role. Generally, shapes with uniform stress distribution are more robust. For instance, a triangle or pyramid is a strong shape as it distributes stress evenly across its surface. Honeycomb structures are also commonly used in 3D printing for their strength and efficiency in material usage.

Can You 3D Print a Gun?

Yes, it’s technically possible to 3D print a gun. However, it’s a highly controversial topic with significant legal and ethical implications. In many regions, it’s illegal to manufacture a firearm without proper licensing and registration. It’s always important to abide by your local laws and regulations. Additionally, 3D printed guns often lack the durability and reliability of traditionally manufactured firearms.

How Long Does It Take to 3D Print Something?

The duration of a 3D print can range from a few hours to several days, depending on the size and complexity of the object, as well as the settings used on the printer (like layer height and print speed). Small, simple designs can often be printed in less than an hour, while large, intricate designs might take over 24 hours.

Is It Hard to 3D Print?

3D printing requires a learning curve, especially for beginners. You’ll need to understand different types of 3D printers, materials, and software. However, with ample resources available online and increasingly user-friendly printers, 3D printing has become more accessible than ever. Patience, experimentation, and a willingness to learn are key to mastering 3D printing.

What are the Pros and Cons of 3D Printing?

Like any technology, 3D printing has its advantages and disadvantages.


  1. Customization: One of the main advantages is the ability to create custom, complex shapes that might be expensive or impossible to produce through traditional methods.
  2. Prototyping: 3D printing is excellent for rapid prototyping, as it enables designers to test ideas quickly and inexpensively.
  3. Reduced Waste: Unlike subtractive manufacturing methods that cut away from larger blocks of material, 3D printing adds material layer by layer, reducing waste.


  1. Limitations with Materials: While there are many materials available for 3D printing, there are still limitations compared to traditional manufacturing methods. Not all materials can be used, and some are still expensive.
  2. Post-Processing: Most 3D printed parts require some level of post-processing, like support removal or surface smoothing, which can be time-consuming.
  3. Speed: While 3D printing is excellent for small, custom parts, it’s currently slower than mass-production methods for large quantities.

What Are the Disadvantages of 3D Printing?

Aside from the limitations mentioned above, 3D printing has some other disadvantages:

  1. Quality: The quality of a 3D printed part can vary depending on the printer’s precision, the printing process used, and the material. Some 3D printed parts may have visible layer lines.
  2. Size Limitations: The size of the object that can be printed is limited by the size of the printer.
  3. Costs: Although the cost of 3D printers has decreased significantly over the years, high-quality printers and materials can still be expensive.

What is the Cheapest Material to 3D Print With?

One of the most affordable materials for 3D printing is PLA (Polylactic Acid). It’s a biodegradable material derived from renewable resources like cornstarch or sugarcane. PLA is user-friendly and works well for many types of prints, making it a popular choice for beginners.

What Materials Cannot be Used for 3D Printing?

Certain materials are unsuitable for 3D printing due to various reasons like high melting points, toxicity, or simply because the technology to print with them isn’t there yet. These include some metals and ceramics, and certain types of glass. Also, many types of food products are currently impractical for 3D printing.

What Materials Cannot be 3D Printed Why?

As mentioned, certain materials cannot be 3D printed due to their physical properties, technological limitations, or safety concerns. For example:

  • Certain Metals: While metal 3D printing is possible, it typically requires specialized, expensive printers. Also, not all metals are currently printable.
  • Glass: Although some forms of glass printing exist, it is difficult due to the high melting point and the need to cool it slowly to avoid cracking.
  • Food: While there have been advancements in food 3D printing, such as chocolate or dough, many types of food are not yet feasible to print.

How Much Does a Spool of PLA Cost?

The cost of a spool of PLA can vary depending on the quality, color, and the brand. As of my knowledge cutoff in September 2021, you can generally expect to pay anywhere from $20 to $50 for a 1kg spool of PLA filament.

Final Thoughts

3D printing is a versatile technology that’s become more accessible to hobbyists and professionals alike over the years. Whether you’re looking to dabble in the world of 3D printing for the first time or upgrade your existing setup, there’s a wide range of printers and materials available to suit your needs and budget.

3D printing can seem daunting initially, with many variables to consider. However, with the correct information and guidance, it’s a hobby that can be picked up relatively easily. Moreover, the payoff is significant in terms of the satisfaction of creating your own 3D objects and the potential financial savings over time.

To conclude, owning a 3D printer can be as expensive or as affordable as you want it to be. What matters is understanding what you want to get out of your 3D printing experience and choosing a printer and materials that align with those goals.
