2. ABS Filament
Acrylonitrile Butadiene Styrene (ABS) is another very popular 3D printing material. It can be used to make 3D printed parts and for prototyping. It can be smoothed and sanded once it is printed. It will melt and extrude through the nozzle easily, but you need to be careful with it when it is cooling. It will shrink, which can cause issues with warping.
ABS is strong, and it can be printed very quickly. It is flexible so that it will not snap easily once printed. Once you print your model, it can withstand higher temperatures without becoming misshapen. It is popular for toys, cell phone cases, and other objects that need to withstand wear and tear.
3. PETG Filament
PETG is short for polyethylene terephthalate glycol-modified, and it is a transparent copolyester. This type of filament is very tough, and it can create very strong models. It has low shrinkage when cooling, and it is good for large, flat surfaces. It also has a smooth finish.
It also is resistant to chemicals, acid, alkaline, and water. People often use this 3D printing material to make jewelry, such as bracelets and rings, or electronics. It has a higher melting point than PLA or ABS. You do need to use a fan with this type of filament because it has a high melting point.
TPU stands for thermoplastic polyurethane, and it is an elastic polymer. It has medium strength, and it is more rigid than other materials, so it is easier to extrude and use. It has high flexibility and durability and can handle greater force than PLA and ABS.
It has low shrinkage and warping, and it is hygroscopic, so it will absorb water particles over time and degrade. It has slower printing speeds because the material is slow to squeeze through the nozzle. It is commonly used for durable items, such as phone cases, rubber mats, power tools, inflatable rafts, medical devices, and stress balls.
What Size Filament Is the Best 3D Printing Filament?
Filaments come in two standard sizes, which are based on the diameter of the filament. They are 1.75 mm and 3.00 mm. Although 1.75 mm filament is more popular, each one has advantages, and the one you choose will depend on your project. You will want to consider the following characteristics:
All filaments are somewhat flexible, but TPU is far more flexible than ABS. If you use the thinner size filament, it will be more flexible. With TPU, since it is already so flexible, you may want to use the 3.00 mm filament, whereas the 1.75 mm filament should be fine for ABS.
When you heat filaments, they melt and then resolidify. Their durability as a finished product is dependent on the layers of the model binding to each other well. The thick filament will take longer to reach its melting point because it has low thermal conductivity. For this reason, the 1.75 mm filament is easier to heat to melting point.
3. Printing Speed
The printing speed is how rapidly the filament comes out of the nozzle and is laid on the build platform. Filament with a higher melting temperature is exuded at a slower rate, which means that the thicker filament will print at a lower speed than the 1.75 mm filament.
4. Durability and Precision
When you are working on a project that requires more precise printing, you will use a smaller nozzle to print the filament. This will work better with the 1.75 mm filament.
For most people, the 1.75 mm filament diameter is the more popular choice. They can be heated up faster, they have more consistency, and they allow higher print speed. However, TPU projects tend to benefit from the 3.00 mm size because it is already so flexible.
What Are the Usages of 3D Printing Filament?
3D printing filament is used to create 3D models and products that you design on your computer. Different products are better suited to different filaments, but you do have choices for many. Take a look at the following uses of the four types of filament listed above:
- Plastic bottles
- Biodegradable medical devices, such as screws, pins, rods, and plates
- Plastic films to store food
- Durable parts that can withstand higher temperatures
- Auto parts
- Medical bracelets
- Chemical containers for household cleaners
- Water bottles
- Other durable plastic items
- Rubber mats
- Phone cases
- Stress toys
- Inflatable rafts
- Power tools
- Medical devices
How to Make a Profit with 3D Printing Filament
Three-dimensional printing offers several opportunities to make a profit. First, you can make products to sell online or in your store. You can make simple toys fairly quickly and sell them. If you notice a toy becoming trendy, you can jump on the trend and make your own.
Another option is to print items for customers. People often have products they want to print, but they may not have a 3D printer or know how to use one. They may prefer to hire you to do it. You can offer your printing services online, and make products for customers.
Another hot industry is rapid prototyping. Often professionals such as architects, engineers, and construction project managers need to have a scale prototype made up of their projects. This is a valuable tool for people in these industries, as they can save time and costs by developing a model of what they are going to build.
You can also make jewelry with your 3D printer, as well as other trinkets that people want to buy. For example, you could create a ring or a necklace and offer it for sale online.
Finally, you can teach a course in 3D printing. As this form of printing gains popularity, more people will want to know how to benefit from it. You could offer classes locally, but you can also travel and do training for businesses.
Many industries benefit from the use of 3D printing. It is a quick and efficient way to develop models and make products. There are many types of filament, and no matter what project you want to do, you will find one that works.
There is no end to the possibilities with 3D printing. Whether you want to use your printer to print objects for customers, print your own products to sell, or improve your business, there are plenty of opportunities to make a profit with your 3D printer.
