Understanding The 3D Printing Ecosystem
Andreas Bastian is a 3D printing scientist at Autodesk.
Pleasure about 3D printing has steadily accelerated over the previous decade — however this pleasure has largely outpaced innovation and improvement within the area. As a researcher in 3D printing applied sciences, I’ve constructed 3D printers utilizing all the main applied sciences, in addition to extra experimental ones.
What I’ve discovered is that many of those applied sciences are composed of very properly-understood supplies, software program issues and mechanical methods — issues that engineers have been doing for many years. This, then, begs the query: Why isn’t 3D printing higher? Why are failure charges so excessive and why is reproducibility so troublesome? It’s clear that it’s not because of working with unique supplies or superior movement management. What’s truly holding again innovation is how we take into consideration these applied sciences: as separate items, relatively than as parts of a system.
A number of Parts Of One Ecosystem
By shifting our perspective when relating to 3D printing, and viewing it as a system of constituent elements, we will change our understanding of its capabilities. Sometimes, we break the system into the next elements:
- Design: This largely means what we, the customers of the know-how, ask it to make for us.
- Hardware: The machines that really do the work of the additive processes to make bodily issues.
- Supplies: These embrace each sort of resin, metallic, ceramic, plastic or uncooked materials which are become practical objects by 3D printing know-how.
- Software program: Converts design knowledge into fabrication knowledge, in addition to the software program onboard the machines and the software program that routes knowledge to the machines.
Probably the most problematic and sometimes forgotten component inside the ecosystem might be discovered within the damaged pathways meant to attach every area to the opposite. Old style methods of thought have prevented us from really realizing the potential of 3D printing. By altering how we take into consideration 3D printing to embrace the techniques nature of the household of applied sciences, we will start to truly leverage it towards actual issues.
We’re Nonetheless Designing For Previous Applied sciences. Virtually the whole lot that’s printed right now has been designed (both consciously or not) for an additional fabrication course of. Identical to designing for pc-numeric-managed machining or injection molding, additive processes excel when they’re leveraged on geometry designed for the precise course of. There are various efforts to develop new design instruments to permit us to design higher for additive processes, however progress begins with recognizing additive manufacturing as simply one other fabrication course of with strengths and weaknesses that have to be thought-about throughout design.
We’re Nonetheless Constructing Prototyping Machines. Present machines are generalists, quite than specialists. As prototyping machines, they’re designed for the bottom widespread denominator of efficiency. This leads to machines that may do many issues, however that may do only a few issues nicely. We have to change the best way we take into consideration the very function of those machines and ask what drawback do they clear up. As an alternative of constructing a machine after which in search of an issue that matches inside it, we have to construct machines round actual issues that want fixing.
Hardware Is Truly About Software program. Along with specializing in actual-world manufacturing purposes, we have to architect the machines to leverage software program. This implies constructing “sensible” machines which are closely instrumented with sensors and which might be net-related to permit for monitoring and actual-time analytics. One instance is the Autodesk Ember, which has sensors that permit it to gracefully recuperate from sudden errors, enhance print reliability, report back to its consumer when it has accomplished a job and permit different customers to examine its state remotely.
Supplies: Multimaterial Versus Mesostructure. Maybe one of many biggest capabilities of 3D printing know-how is its means to cheaply implement complexity in supplies. As designers, we’re used to sure properties being tied to varieties of matter, and we name this a “materials.” For instance, a picket beam and a bit of paper have dramatically totally different properties and serve totally different functions, however are each finally cellulose fibers (wooden pulp). What truly units them aside is how this cellulose is organized and structured. We name construction that’s bigger than microcrystalline (tens of microns and under) and smaller than human scale (centimeters to meters) mesostructure.
A standard objective of 3D printing is to have the ability to print a number of supplies from one machine to achieve a number of properties for one object or design. Nevertheless, mesostructure permits designs to get extra worth out of a single materials. As an alternative of counting on totally different supplies for various efficiency-particular properties, a designer can use a number of mesostructures to create an object with the required efficiency traits (tender, agency, elastic, breathable, and so on.) utilizing only one machine and one materials.
With the mesostructure precept, designers not have to compromise and may, in reality, design with much more flexibility and functionality than earlier than. This unlocks an enormous untapped functionality of 3D printers and opens new frontiers in design.
Multimaterial as a paradigm is sure to the set of recognized supplies and properties.
Mesostructure as a paradigm permits designers to work with acquainted efficiency properties, in addition to people who have by no means existed in nature.
Bringing It Collectively
As soon as we will truly design these parts to interface with one another and their corresponding applied sciences, and construct true manufacturing options with the ensuing methods, we will combine all the things that the business has discovered over the previous 25 years and begin making use of it:

- Openness: Accessibility is massively essential for enabling innovation. If the barrier to an software or new materials is the event of a full machine, it gained’t be overcome.
- Modularity: This strategy is important each for partaking purposes and for leveraging a broader suite of supplies.
- Connectivity: Community connectivity will permit for knowledge analytics and deeper integration with software program to help for much extra refined management.
- Path: As we’ve seen with the legendary shopper 3D printing market, the business gained’t advance if it pursues the flawed issues. We should apply this energy know-how the place it makes the most important influence.
The core applied sciences will not be holding again the business, it’s the system by which they reside that’s.
