Print quotas, limits and prepaid balance

Print quotas & usage limits

A print quota is a cap on how much a student or user is allowed to 3D print in a given period - by number of prints, filament grams, print time, or cost. SimplyPrint lets you set those allowances per user group, give each person a prepaid balance to spend, and reset everything automatically each week, month or term - so a single student can't burn through a lab's filament and you never have to police the printers by hand.

Stop one student printing the whole spool

Open up a lab of 3D printers to a class and a few students will happily print figurines until the filament runs out. Quotas put a fair allowance on every account - so each student gets, say, 5 prints, 200g of filament or two hours of print time a week - and the limit enforces itself. No clipboard, no honour system, no teacher standing over the machines.

Quotas, limits and balance are part of the School and Enterprise plans, the same plans built for classrooms, university labs, libraries and makerspaces.

Limit prints, filament, print time or cost

Set an allowance on whichever measure matters for your lab. You can cap the number of prints, grams of filament, total print time, cloud-slice credits, or the cost of printing in your account currency - and combine several at once (for example 10 prints and 500g per month). A material-grams limit can even be scoped to a single filament type, so a special resin or engineering filament gets its own tighter cap.

When someone reaches a limit, their next print is blocked with a clear message showing which allowance ran out and when it resets - no silent failures, no confusion at the printer.

Different allowances for different groups

Allowances attach to user groups, so you decide what each role gets. A first-year class can get a small weekly quota, an advanced or specialist group a larger one, and teachers can be exempt entirely. Every member of a group inherits its policy automatically, so onboarding a new class of students is nothing more than adding them to the right group.

You can also set hard per-job limits per group - a maximum print time and maximum print dimensions (X/Y/Z), with optional tighter caps on specific printer models - so no single job ties up a printer for two days.

Reset every day, week, month or term

Pick how often each allowance refreshes: daily, weekly, monthly, a custom number of days, a fixed date range, or by academic semester. The semester option follows the terms you define in your school settings - quota refreshes when a new term starts and stays frozen over the breaks - so a per-term print allowance is one setting, not a calendar reminder you have to action by hand.

You also control the anchor: reset on the calendar (start of each week/month), relative to when a student first printed, relative to when they joined, or from a specific date you choose. Unused quota can optionally roll over into the next period, up to a cap you set.

Built around the school year

Define your academic terms once under School settings - name each semester and its start and end dates - and the semester reset period uses them everywhere. The option appears automatically for schools that run on terms; libraries and makerspaces, which don't, simply don't see it, so the choices you're offered always fit how your institution actually runs.

At the start of a new term you can also bulk-reset every selected user's usage to zero in one click from the users page - a clean slate for the whole class without editing accounts one at a time.

Give each user a prepaid print balance

Alongside quotas you can run a prepaid balance: every user gets a credit balance, and each print deducts its cost. Set a starting balance, auto-refill it on a schedule (a fixed top-up or a top-up to a target, with an optional maximum), and choose whether running out of balance blocks printing or just gets logged.

That second mode matters for makerspaces and labs that bill usage: in tracking mode the balance never blocks a print, it just records the cost so you can report or charge for it later through the API and webhooks - the same pattern print-management tools like PaperCut use. In enforced mode an empty balance stops the next print until it's topped up. See the quotas & limits guide for the full walkthrough.

Students can ask for more, teachers approve in a click

A hard cap that needs a teacher to log into settings every time is its own kind of friction. When a student hits their limit, SimplyPrint can show them a Request more button right where the print was blocked. Their request lands in the teacher's quota-requests inbox on the school dashboard, where you approve or deny it inline - adjust the amount, add a note, and optionally notify the student.

You decide per group whether students can request more at all, and who gets emailed when a request comes in (nobody, all teachers, or specific admins). Teachers can also top up or reset any individual's quota and balance directly from the users page.

Fair when a print cancels or fails

A quota that charges a student for a print that failed halfway through isn't fair, and they'll tell you so. You control exactly how cancelled and failed prints count: charge the full amount, charge nothing, or pro-rate by how far the print got, with an optional grace window so a quick cancel in the first few minutes costs nothing. Filament can be set to always count (it was extruded either way) while the print itself doesn't. Sensible defaults are already in place, so it's fair out of the box.

Always-visible usage, for students and staff

Every user sees their own quota and balance as progress bars in the top bar and on their account page, with a countdown to the next reset and a full balance transaction history. A warning appears once they're near a limit, so running out is never a surprise. Staff with the right permission see each user's remaining allowance right next to their name in the queue, so a teacher reviewing prints knows at a glance who has room left.

Plan availability

Quotas, limits and prepaid balance are one feature, included on the School and Enterprise plans. The Free, Basic, Pro and Print Farm plans don't include usage limits - they're built for individual makers and production farms rather than shared, multi-user labs.

Frequently asked questions

You can cap the number of prints, grams of filament, total print time, cloud-slice credits, or the cost of printing in your account currency. Several can apply at once - for example 10 prints and 500g of filament per month - and a filament limit can be scoped to a single material type. You can also set hard per-job limits: a maximum print time and maximum print dimensions, with optional tighter caps on specific printer models.
Yes. Allowances attach to user groups, so a first-year class, an advanced group and your teachers can each have their own policy - or no limit at all. Every member of a group inherits its quota automatically, so adding a new class of students is just a matter of putting them in the right group.
You choose: daily, weekly, monthly, a custom number of days, a fixed date range, or by academic semester. The semester option follows the terms you define in your school settings, so quota refreshes when a new term starts and stays frozen over the breaks. Unused quota can optionally roll over into the next period, up to a cap you set.
Yes. Define your academic terms under School settings - each with a name, start and end date - then set a quota's period to Semester. It resets cleanly at the start of each term. The semester option only appears for institutions that run on terms; libraries and makerspaces use the date-range or monthly periods instead.
Their next print is blocked with a clear message showing which allowance ran out and when it resets. If you've allowed it for their group, they'll also see a Request more button that sends a request to the teacher's inbox, where you can approve or deny it inline and adjust the amount granted.
Each user can be given a credit balance, and every print deducts its cost. You set a starting balance and an optional auto-refill (a fixed top-up or a top-up to a target, on a schedule).

Yes - you control it. For cancelled and failed prints you can charge the full amount, charge nothing, or pro-rate by how far the print got, with an optional grace window so a quick cancel costs nothing. Filament can be set to always count while the print itself doesn't. Sensible defaults are already in place, so it's fair without any setup.
