STEM Club Starter Kit: What Filament and Colors Work Best for a School's First Printer

The printer just showed up, the club is meeting Thursday, and somebody has to decide what filament to actually order before students walk in the door. This is the practical, no-guesswork version of that decision — what to buy first, what to add once the club is running, and roughly what it costs per student for a semester.

Core Recommendation: Start Narrow

The instinct when setting up a new STEM club printer is to order a huge color assortment right away, because more colors feels like more possibility. In practice, that instinct works against you in year one. A new club is still learning to use the printer reliably — dialing in settings, figuring out bed adhesion, understanding what makes a print succeed or fail. Every material variable you introduce during that learning phase is one more thing that could be the cause when something goes wrong, which makes troubleshooting harder for you and more confusing for students.

Start with PLA Basic in three to four core colors. That's enough variety for students to feel some ownership over their projects without turning every print troubleshooting session into a guessing game about whether the color, the spool, or the printer is the problem. Once students are comfortable with the basics and start attempting functional projects — parts that need to snap together, withstand handling, or survive being dropped — add PLA+ to the shelf. The step up in toughness matters more once projects start being used rather than just displayed. Our PLA+ vs. PLA Basic comparison covers exactly when that upgrade earns its cost, which is useful to have on hand when a student asks why their club spool is a different color of PLA than the poster on the wall.

A Realistic Starter Shopping List

Here's a first-semester list sized for a typical STEM club running one printer with roughly 15–25 active students across the semester, printing a mix of demonstration pieces, small individual projects, and one or two group builds.

Item	Quantity	Purpose
PLA Basic — core colors	Covered by one Everyday Essentials Bundle	General printing, first projects, demonstrations
PLA Basic — single spool, backup color	1 spool	Buffer for a popular color running low mid-semester
PLA+ — 1–2 colors	1–2 spools	Functional projects once students are past the basics

The PLA+ Everyday Essentials Filament Bundle is built to cover exactly this kind of "first semester" need — a curated color range in one purchase instead of assembling individual spools and guessing which colors you'll actually run out of first. Starting with a bundle also simplifies your budget request: one line item instead of five or six separate spool purchases makes for an easier approval conversation with whoever signs off on club supplies.

Choosing Your Core Colors

Since we're recommending you start narrow, the specific colors you pick for that first order matter more than they would in a bigger assortment. A few practical guidelines that hold up across most clubs:

• Pick one true black or white and one true primary color first. These print predictably, photograph well for any club showcase or social media post, and rarely clash visually with whatever a student is trying to make.
• Avoid starting with your most delicate specialty colors — silks, glow, or color-changing effects are genuinely fun, but they behave slightly differently on the printer than standard colors and are better introduced once your club has a baseline of successful prints under its belt.
• Ask your returning students what they'd actually use before finalizing a color list, if you have any club members from a prior semester. Their answers are usually more accurate than guessing what a new group will want.

What to Add in Year Two

Once your club has a semester or two of printing experience under its belt, a few additions make sense:

• PETG Basic for functional or outdoor-facing club projects — parts that need to hold up to more impact than PLA handles well, or that might end up outside where PLA's lower heat tolerance becomes a real limitation. PETG Basic runs hotter (230–250°C nozzle, 70–90°C bed) than PLA, so this addition works best once students already have a solid baseline of successful PLA prints and some troubleshooting experience to fall back on.
• One engineering material, if the club runs a robotics or engineering track specifically. This is a bigger step up in both cost and printing difficulty, so it's worth reserving for a club that has a specific project — a robot chassis, a load-bearing bracket, a competition part — that genuinely needs the added strength or heat resistance, rather than adding it just because it sounds advanced. Our heat-resistant filament comparison is a useful reference once you're at this stage and need to choose between options.

Resist adding both in the same semester you also grow the club's membership significantly — new members need PLA-level fundamentals first, regardless of what your more experienced returning students are ready for.

Budget-Per-Student Framing

Schools respond better to a rough per-student number than to a total dollar figure with no context, so here's how to think about it. A single small student project — a keychain, a simple mechanism, a math manipulative — typically uses somewhere in the range of 10 to 40 grams of filament. Across a semester of regular club meetings, with each student completing several individual projects plus contributing to shared group prints, a reasonable planning estimate is roughly $3–$8 in filament cost per active student for a semester, depending heavily on how large and how frequent their individual projects are. This is a general planning range, not a fixed number — a club doing mostly small demonstration prints will land at the low end, while a club running larger functional projects for every student will land higher.

The practical takeaway for budgeting: filament cost per student is genuinely low compared to the printer itself. The bigger line item to plan for is buying in bundles rather than piecemeal, since that's where you avoid both overspending on colors nobody uses and running out mid-semester on the ones everybody wants.

A Note on Storage and Longevity

A school club printer often sits unused for stretches — summer break, holiday breaks, gaps between meeting schedules — which makes filament storage worth a moment of planning even for a first-semester setup. Keep spools in their original packaging or a sealed container when not in use, and store them somewhere that doesn't swing wildly in temperature or humidity, like a supply closet rather than a window ledge. PLA and PLA+ are both reasonably tolerant of normal indoor storage conditions for a semester or two, but a spool that's been sitting open in a humid room for a long break can print less cleanly than a fresh one — worth knowing before you assume a disappointing first print back after break is a printer problem rather than a storage issue.

Setting Club Expectations Around Filament

Beyond the ordering decisions, it helps to set a few ground rules with students early so a limited color and material supply doesn't turn into a source of constant friction. Let students know upfront which colors are "always available" versus "special order only" so requests stay realistic. Consider a simple sign-up or reservation system for print time once the club grows past a handful of regulars, so the printer's limited hours get distributed fairly rather than going to whoever asks first each meeting. And treat failed prints as a shared club resource question, not an individual student's fault — a clear, calm process for handling a failed print keeps the printer's limited material budget from becoming a point of tension between members.

Getting Buy-In From Administration

If you're pitching a new STEM club printer to a principal or department budget committee, a few framing points tend to land better than a general appeal to "STEM enthusiasm":

• Lead with the low recurring cost. The narrow starter list above keeps first-semester filament spending modest and predictable, which matters more to a budget approver than the exciting-but-vague idea of "unlimited color options."
• Point to a specific first-semester deliverable. A showcase, a science fair table, or a display case of student projects gives administration something concrete to expect in return for the investment, rather than an open-ended ongoing expense.
• Mention the multi-year value of the printer itself. Filament is a recurring but modest cost; the printer is the one-time investment that makes years two, three, and beyond far cheaper than year one, since you're only budgeting for material at that point.

Getting Started

Order the PLA+ Everyday Essentials Filament Bundle as your semester-one foundation, and if your printer supports automatic color switching, the PLA Multicolor Starter Bundle for AMS is worth adding for projects where students want more color variety in a single print without you manually swapping spools between sessions. Add standard PLA Basic and PLA+ single spools as backups for whichever colors prove most popular once the club is running. Everything here is available at Filazoo's collection — start narrow, watch what your club actually uses, and expand from there.
