FDM (fused deposition modelling) 3D printing is a popular choice for beginners due to its affordability and availability.
With a 3D printer, you can create customized items, prototypes, and replacement parts.
When getting started with 3D printing, it is important to choose the right printer, understand the different printing processes, and consider essential hardware and accessories.
What is 3D printing?
3D printing is a revolutionary technology that allows you to create three dimensional objects from a digital file. It’s an additive manufacturing process that builds objects layer by layer, using less material than traditional manufacturing methods. This basically takes a cross section of a three dimensional model and prints it in plastic. Similar to how a laser printer prints out a one layer piece of paper, the 3D printer prints many layers, thus making one solid part when all is said and done. This technology offers numerous benefits, such as the ability to produce complex shapes and geometries that were once difficult or impossible to create.
A stereolithography file is the standard file type used for 3D printing. Normally a model is created using computer aided design software then the file is exported into the .stl file format for slicing software.
3D printing has diverse applications, from prototyping in the engineering industry to creating lightweight structures. Compared to traditional manufacturing, 3D printing is faster, has lower setup costs, and offers more design flexibility.
The future of 3D printing looks promising, with ongoing research and development in areas such as volumetric printing, which could revolutionize the manufacturing process even further. With 3D printing, you have the control to bring your digital designs to life in a tangible and efficient way.
The history of 3D printing
During the 1980s, significant developments in additive manufacturing paved the way for what we now know as 3D printing. Early pioneers like Hideo Kodama, Charles Hull, and Carl Deckard made crucial technological advancements that laid the foundation for this groundbreaking technology.
In the early years, different additive manufacturing processes such as Stereolithography (SLA), Selective Laser Sintering (SLS), and Fused Deposition Modeling (FDM) emerged as the building blocks for the industry.
Over the following decades, 3D printing applications expanded and diversified, with companies and startups experimenting and innovating in various sectors such as automotive companies, the medical industry, all experimenting using 3D printed parts in their rapid prototyping.
Today, 3D printing has become accessible to the general public, with prices declining and quality improving. The possibilities are endless, as ongoing innovations and ideas continue to shape the future of 3D printing.
3D printing: Starting at the beginning
To understand the basics of 3D printing, let’s start by exploring the process and technologies involved in creating three-dimensional objects from digital files.
There are different types of 3D printing technologies, including Fused Deposition Modeling (FDM), Stereolithography (SLA), Selective Laser Sintering (SLS), Digital Light Processing (DLP), and Binder Jetting.
FDM (fused deposition modeling) 3D printing is a popular choice for beginners due to its affordability and availability. It involves melting plastic filament and extruding it through a nozzle to create the object layer by layer.
To ensure successful prints, it’s important to choose the right print settings, use support structures for complex geometries, and regularly clean and maintain your 3D printer.
Additionally, troubleshooting common issues like warping, layer adhesion problems, stringing, failed prints, and quality issues is essential for achieving optimal results.
What you can 3D print?
You have a wide range of possibilities when it comes to what you can print using 3D printing technology. With a 3D printer, you can create a variety of objects that cater to your needs and interests. Here are some popular 3D printing projects and creative uses for 3D printing:
Customized phone cases and accessories: Personalize your phone with unique cases, stands, and holders.
Home decor and ornaments: Design and print your own decorative items, such as vases, candle holders, and figurines.
Prototypes and models: Bring your ideas to life by creating prototypes and models for product testing or visual representation.
Replacement parts and repairs: Save time and money by printing replacement parts for broken items or repairing damaged objects.
While there are many possibilities, it’s important to note that there may be limitations to what you can print with a 3D printer, such as size and complexity. However, with the continuous advancement of technology, the potential for innovation and creativity in 3D printing continues to expand.
Different 3d printing processes (and their pros and cons)
Now let’s explore the different 3D printing processes and their pros and cons, building upon the wide range of possibilities for what you can print using 3D printing technology.
Process Pros Cons FDM Fast printing speed, low cost, wide range of materials Low resolution, prone to breaking, requires support and wasted material SLA High accuracy, high resolution, durable parts More expensive, limited materials, requires support SLS High accuracy, medium surface finish, no supports required, high throughput Not possible for smooth surface finish without post-processing, limited materials RDM’s 3D Printing Services Leveraging advanced 3D printing technologies, fast parts and prototyping, wide selection of materials and dimensional accuracy None mentioned
Each 3D printing process has its own advantages and limitations. FDM is a popular choice for economical proof-of-concept models and large parts, but it has lower resolution and may require support structures. SLA offers high accuracy and excellent surface finish, making it suitable for functional prototypes, but it is more expensive and has limited material options. SLS provides high accuracy and no need for supports, making it great for strong, functional models, but it requires post-processing for desired surface finish. RDM’s 3D Printing Services offer a wide selection of materials and fast turnaround time. As technology advances, we can expect future advancements in 3D printing technology to bring even more possibilities and improvements to the industry.
The drawbacks to keep in mind
However, it’s important to consider the drawbacks of 3D printing technology. While there are numerous advantages, there are also limitations and challenges to keep in mind. Here are some factors to consider when comparing 3D printing with traditional manufacturing:
Build Size Consideration: Majority of 3D printers have small design chambers, requiring parts to be divided into sections for printing larger items. This can result in additional work and cost.
Materials Consideration: The availability of materials for 3D printing is limited, with most materials being made of plastics. This limits applications requiring high strength.
Machine Cost: 3D printing machines are expensive compared to traditional manufacturing machines, and the cost of running these machines can be higher as well.
Safety Concerns: There’s a potential for creating dangerous items such as guns and knives, with the difficulty of tracing their origin. This raises alarming implications for safety and security.
Considering these drawbacks will help you make an informed decision about incorporating 3D printing into your home projects.
How to pick your first 3D printer
For those seeking their first 3D printer, identifying the ideal option for home use involves considering key features and capabilities.
One of the first things to decide is the type of printer that suits your needs. FDM printers are versatile and can handle various filaments like PLA, ABS, and PETG. They’re suitable for prototyping, functional parts, and larger-scale prints. On the other hand, resin printers produce highly detailed, smooth, and precise prints, making them perfect for small-scale models, jewelry, dental, and medical applications.
The next step is to evaluate the print volume needed for your projects and check the supported materials for the printer. Additionally, consider the print speed, reliability, and supported software and connectivity options.
Finally, compare the maximum print size, supported materials, nozzle size, presence of a heated bed, filament detection, and enclosed frame features of different printers to make an informed decision.
