To delve deeper into Alan’s impactful work and insightful perspectives, his comprehensive blog serves as an excellent resource for anyone interested in making and design.

For Alan Ware, when considering how to choose your 3D printer filament, the most significant criterion, hands down, is the price. He strongly emphasizes, “It’s not that the other criteria aren’t important, but it’s been my experience that many who come new to 3D printing expect too much too soon.” This perspective highlights a pervasive and common misconception among beginners who often envision a seamless, “one-button” printing experience where complex parts magically appear without issue. Alan sharply contrasts this idealized view with the often challenging reality known by experienced practitioners: “They imagine that you just hit a button and the part magically appears with no issue. Those of us continuously fighting with the machines know better. Building things is hard. Building things reliably and consistently is even harder. Doing all of the previous with a 3D printer…well, you get the idea.” While he fully acknowledges the natural human desire for high-quality outcomes – a sentiment he articulates as, “They want the highest quality possible, because it’s their baby and that is understandable” – he cautions emphatically against prioritizing premium materials too early in the learning curve or during the iterative prototyping phase.

The pursuit of pristine quality and expensive materials early on often comes with a significant financial cost, which Alan views as potentially wasteful during the iterative and experimental prototyping stage. He firmly believes that effective prototyping and design necessitate a strategic focus on specific, isolated aspects of a design at any given time. In the initial phases of a project, dedicating excessive resources and attention to material quality can prematurely divert focus and funds from more critical developmental areas such as ensuring structural integrity, rapidly iterating on design flaws, or conducting essential functional testing. Alan’s practical philosophy is succinctly captured in his powerful statement: “I’m a big fan of doing what I can with the worst materials than doing the worst with good materials.” This principle underscores the immense value of mastering the fundamental printing process and troubleshooting techniques with less expensive, more forgiving materials before making substantial investments in specialized ones. Naturally, as one gains more experience, a clearer understanding of specific project requirements emerges, and more informed decisions about advanced 3D printer filament selection can certainly be made. However, beginning with affordable, general-purpose filament is, in his view, the most prudent, effective, and sustainable starting point for any enthusiast or aspiring maker.

Alan Ware’s operational practice involves primarily utilizing whatever 3D printer filament is readily available, but this approach is deeply rooted in a clear pedagogical motive rather than mere convenience. He elucidates, “most of how I interact with 3D printers these days is teaching other people how to use them.” While he still engages in a significant amount of prototyping for his own projects, his teaching methodology is meticulously designed to be universally applicable and robust: “with that aim, I try to teach in a way that will be useful in the greatest number of possible situations.” This pragmatic perspective acknowledges that real-world 3D printing environments are rarely ideal or perfectly controlled. Therefore, cultivating a profound understanding of how to manage, troubleshoot, and adapt to less-than-perfect printing conditions is absolutely paramount for long-term success. While the vast array of 3D printing options and specialized materials available can be overwhelming, a deeper and more practical understanding emerges from rigorously analyzing and optimizing one’s specific printing environment and workflow. Alan powerfully illustrates this by contrasting a shared machine in a hacker space or school lab – where diverse users, varied settings, and different materials might be involved – with a personal printer used exclusively by one individual. He strongly advises against ignoring such environmental considerations, stating, “it is a mistake to ignore considerations like this in 3D printing, especially with the nature of the internet, what worked for someone else might not specifically work for you.” While he acknowledges the valuable and extensive discourse surrounding specific 3D printer filament quality and characteristics, he steadfastly emphasizes that for beginners, mastering the foundational aspects of printer operation, maintenance, and systematic problem-solving takes precedence, with the crucial caveat of avoiding genuinely substandard or problematic filament altogether.

Alan Ware’s Essential Advice for 3D Printing Beginners

Alan Ware’s straightforward and highly practical advice for individuals embarking on their 3D printing journey is succinct and powerful: “start small, start cheap, and don’t obsess over quality in the beginning.” He masterfully likens 3D printing to a complex, multifaceted discipline that seamlessly integrates numerous related yet distinct skill sets. As he meticulously details, “There’s actually just making the 3D printer run and troubleshooting, filament selection, 3D modeling, mesh editing, and the list goes from there.” Each of these individual components presents its own unique learning curve, demanding considerable time, unwavering patience, and often leading to moments of frustration. Alan cautions emphatically against approaching 3D printing with an oversimplified or naive mindset, specifically warning against the expectation that “how easy it’s gonna be” – he asserts that such an attitude is fundamentally misguided and will inevitably lead to disappointment. However, he quickly clarifies that 3D printing is by no means an insurmountable challenge or beyond anyone’s grasp. He further elaborates with profound insight, “Just don’t fall into to the trap of thinking that computers/technology are going to fix every little thing. As long as we’re, as in human beings, are the people building the tech, there are going to be issues.” The ultimate key to sustained progress and mastery, according to Alan, lies in realistically accepting these inherent challenges and actively developing systematic strategies to anticipate, address, and mitigate them effectively.

When selecting a good 3D printer filament for beginners, Alan strongly recommends starting with PLA (Polylactic Acid) filament. Its primary and most significant advantage is that it generally “doesn’t need a heated build plate and is a ‘friendly’ plastic,” making it incredibly forgiving and easy to work with for initial experiments and learning. Given the multitude of factors involved in achieving successful 3D prints, mastering the fundamental mechanics and troubleshooting with PLA before introducing additional variables like heated beds is a sensible and highly effective progression. Once a solid foundation in basic 3D printing is established, he suggests gradually moving on to ABS (Acrylonitrile Butadiene Styrene) based on its widespread availability, common applications in engineering, and significant ubiquity in the industry, despite its occasional “annoying” printing characteristics, such as notorious warping tendencies and the emission of fumes that require proper ventilation. Another noteworthy recommendation he makes is PETG (Polyethylene Terephthalate Glycol-modified). Alan observes, “I’ve seen some really good results with PETG, but I’ve heard temperature considerations really come into play hard when dealing with that.” This highlights PETG’s excellent balance of strength, durability, and ease of printability compared to ABS, but also underscores its sensitivity to precise temperature settings for optimal results. Ultimately, with the constantly expanding range of 3D printer filament options available, the decision boils down to a clear and precise understanding of your specific project’s objectives and desired outcomes. Building a reliable printing environment and developing an efficient workflow around these objectives, all while being mindful of budget and avoiding excessive costs, is paramount in the initial phases of your 3D printing journey. Alan Ware masterfully rounds off his advice on how to choose your filament by emphasizing that “Successful design is all about substitution and compromise, at least in the early phases. I’ve found that lesson can be a bit hard for the uninitiated to grasp in the beginning.” This pragmatic and adaptable approach ensures sustainable learning, effective problem-solving, and ultimately, greater success in the dynamic and rewarding world of 3D printing.
