More Cool Things About 3D Printing

From pencil holders to robotic arms, 3D printing can do a whole lot. What might have taken hours, days, and even months to build can now be 3D printed using this technology to create your unique designs quickly. Even though there are a lot of 3d printing ideas for you to start getting things printed, 3D printing technology is still incredibly new to many. So we’re going to answer some of the most common questions about 3D printing and turning things to 3D.

Can 3D Printers Print Metal?

Generally speaking, yes they can! However, the process and the materials used to print metal is slightly different. In fact, not all printers can print metal. In 3D printing, there are different manufacturing processes. For 3D printing metal, there are three top ways to 3D print—metal-binding jetter, powder bed fusion, and directed energy deposition. These methods use metal powder or metal wires to layer the materials and print the design in 3D. However, 3D printing metal can’t be done at home because of how expensive the machine to support this type of 3D printing is.

When it comes to 3D printing metal, there are people who may choose to use a laser cutter instead. The reason is that 3D printed projects using metal can be costly and time-consuming. However, the two are quite different. 3D printing is an additive process, while laser cutting is a subtractive process. Depending on your needs, those that are looking to create multiple pieces at a quicker pace may choose the laser cutter as it can conveniently cut multiple materials and larger size.

With digital trends of raw and rustic design, you might be considering 3D printing cool things at home with metal. However, printing metal is extremely costly due to its process and the machinery required. If you’re looking for cool things to 3D print at home with a metal-looking finish, we recommend using materials on the market that can create metal-like 3D printed objects instead. These materials give the illusion that your 3D printed pencil holder or camera mount is made out of metal but without the actual cost.

What Are Some Cool Things 3d Printers Can Do?

One of the cool things 3D printing can do is be used in the field of science for research. Scientists have successfully 3D printed bespoke equipment and even body parts in the laboratory. Using 3D printed human organs, surgeons are able to use this life-like organ to perform practice surgeries. With today’s advanced technology, 3D printed organs also allow surgeons to work on difficult procedures and rare scenarios without real-world consequences, such as bleeding.

Thanks to 3D printing, it has also made highly-customizable prosthesis possible. One of the coolest things about 3D printed prosthesis is that they can create custom fits for the patient and also a much lower cost. Instead of creating static designs that are “one size fits all”, 3D print gives companies the opportunity to create products that are affordable and personalized. What would have cost lots of money to create is now more accessible thanks to 3D printed prostheses.

Beyond science, 3D printed homes and shelters have also become one of the cool things to 3D print across the world. To address the housing issue around the world, companies have been using this technology to print emergency shelters and 3D printed homes. With this technology, companies and cities can build a community in a much shorter amount of time and for a cost cheaper than traditional home building methods. Each home inside the community can then be purchased at a more affordable cost.

What Would Be Something Cool to Make With a 3D Pen?

If you’re looking for a smaller and more affordable option, 3D pens are a great choice to get your creativity flowing too. 3D pens are affordable, easy to manage, smaller in size, and more practical. Using a 3D pen you can easily turn things to 3D. Design and personalize cool things to 3D using your imagination and 3D pen. From making repairs by using 3D pen as an adhesive to creating pieces of artwork, 3D pens give you the flexibility to draw your ideas immediately.

If you love architecture and buildings, companies have created kits that allow people to replicate architectural structures and other cool things with a 3D pen. For boardgame lovers, you 3D print your own figurines by drawing it with your 3D pen. You can also turn your favorite cartoon show characters or movie heroes into 3D. While a 3D pen allows you to draw 2D things to 3D, their limitation tends to be the size of the project you can make. If you’re looking to 3D print a life-size chair, it may be easier to use a printer because 3D pens may not be able to create something as durable.

What Are Some Cool Things That Take Less Than an Hour to 3d Print?

If you’re short on time and looking for some quick projects, there are lots of cool things to 3D print in less than an hour! In our 3D print list above, projects like the keychain, hinge, handles, bookmarks, smartphone stand, and whistles are some of the cool things to 3D print in less than an hour.
