3D Printing 101: What is 3D printing?
3D printing, also known as additive manufacturing, refers to processes used to create a three-dimensional object in which layers of material are formed under computer control to create an object.
This process provides makers with incredible flexibility in being able to make objects that would be impossible to create through traditional manufacturing methods such as subtractive manufacturing, where material is removed to make the object (machining or woodworking), or injection molding where the flow of the molds are the limitation.
Types of 3D printing
SLA (Resin + UV Laser)
SLA works by exposing a layer of photosensitive liquid resin to a UV-laser beam so that the resin hardens and becomes solid.
Stereolithography has great accuracy, but the resin is expensive and the overall process is messy and unsafe.
SLS (Powder + Laser)
SLS is similar to SLA, but the key difference is that this type of 3D printer uses powdered material in the build area instead of liquid resin. A laser is used to selectively sinter a layer of granules, which binds the material together to create a solid structure.
Selective Laser Sintering is expensive, necessitates using messy powders and is space intensive.
PP3 (Powder + Ink)
Powder printing provides a full color 3D printing option using a combination of powder and ink.
This provides an impressive result, but these machines are expensive, and the finished prints are brittle and require labor-intensive post-processing.
FDM (Plastic + Heat)
FDM is the most common 3D printing method used in desktop 3D printing. Thermoplastic filament is heated and extruded through an extrusion head that deposits the molten plastic in X and Y coordinates, while the build table lowers the object layer by layer in the Z direction.
Fused Deposition Modeling is the most viable consumer option with a great balance of capabilities, ease of use and it costs less.
Ease of use versus capability
The most viable 3D printing technology for consumer use is determined by comparing the ease of use and capabilities of each printing method.
3D Printing in the classroom
Now more than ever, today’s classroom relies on a suite of advanced technologies to accelerate the learning process and foster a more collaborative environment, giving students and educators alike innovative new ways to achieve curriculum goals in the 21st century.
Decades ago, computers revolutionized the age of information and now they play a pivotal role inside of today’s learning initiatives.
3D printing is blazing a similar trail of progress as more and more are put to use in our homes, businesses and schools.
Cycle of student impact
In the same way that the adoption rate of modern computing was driven by educators in the 80’s and 90’s, 3D printing is a technology that is readily being adopted and utilized by educators to prepare students with skills that employers are seeking.
Robo at school
3D printing provides a world-class learning platform for students and teachers alike.
Our products give students a wonderful way to develop their own designs, solve problems, explore new ideas, and then print and test their ideas right away — and they’re great tools that fully support the Next Generation Science Standards (NGSS).
Teaching the design cycle
3D printing gives nearly any idea a bigger arena to flourish, ensuring a physical means to explore and more critically evaluate concepts — and those objects related to them — that supersede the limitations of two-dimensional space.
From ideation, to creation, to execution — all key steps within an object’s “design cycle”— each finished 3D print reinforces those new classroom standards and efficiencies that are integral to the learning process.
To think up an object and bring it into existence with rapid efficiency, as something to see and touch, also represents a major historical achievement — another kind of technological revolution set to inspire the young minds whose contributions undoubtedly move us forward in our tomorrow.
3D thinking is the movement
Project based learning
Now, more than ever, project based learning is becoming a major focus in this new age of education.
Project-based learning gives students a level of autonomy that pushes them to think of new ways to solve problems as they complete assignments.
This innovative approach challenges them to seek answers by doing, wherein facts become evident based on what they learn along the way. Instead of following a universal, one-size-fits-all approach to learning, how the student discovers information becomes a unique experience that works in parallel with how they think as an individual.
3D Printing provides learning opportunities in many subjects
Provides learning opportunities at many levels
Elementary / Middle School
By accessing and developing key foundational skill sets through Robo 3D printers, students begin to understand important lessons about trial and error, problem-solving, patience and time management for a wide range of projects.
Secondary / High School
Students at this level gain an edge as early adopters of 3D printing — providing them with newfound creative skills that translate to career success for future jobs within the fields of science, technology, engineering, design, mathematics and manufacturing.
University / Trade School
Once in the midst of establishing their careers within the STEM-related fields, Robo 3D printers provide students the ability to learn in a more hands-on way, further elevating critical thinking and analysis in a concept’s / project’s “design-cycle,” while giving them a fully tactile means to create the solutions they seek in real time.
3D printing content aligns with STEAM and NGSS
From gaining insight on the inner-workings of a DNA helix, to the technicalities involved in vehicle construction, to understanding the physics involved in rollercoaster design — and much more — the learning opportunities provided by 3D printing are endless!
Robo 3D printers inspire a better way to learn
As traditional classrooms evolve to support more STEAM-related subjects and activities, students at the elementary, secondary and university levels need the necessary tools to thrive in this new approach to learning.
