Planned Servicing, Rolling Contracts and Fleet Condition Reporting for Multi-Printer Setups
Last updated: August 2026
One printer down is an inconvenience. A DT room with four machines and two of them dead in the week before a deadline is a different problem — and it is almost always predictable. Hotends, PTFE, build plates, extruder gears and AMS feeders wear on a schedule you can plan around. We service multi-printer setups on a planned cycle instead of waiting for the phone to ring, tell you what is worn and what is close to failing, and give you a written picture of the fleet you can put in front of whoever signs off the budget. We work with schools and colleges, university workshops and makerspaces, design and architecture studios, and small manufacturers running prototyping machines.
Tell us what's happening — we'll get back to you same day.
Every machine serviced on a rolling cycle rather than all at once, so you are never in the position of having the whole room out of action. Sequencing is agreed around your calendar, not ours.
A retainer covering the planned visits plus a defined route in when something goes wrong between them. Scoped and quoted to fleet size, model mix, usage and location — there is no off-the-shelf price because there is no off-the-shelf fleet.
A machine-by-machine record after every visit: what was done, what is worn, what is likely to need replacing next and roughly when. This is the document that turns an unpredictable repair line into a planned budget.
Hotends, PTFE tubing, build plates, nozzles, extruder assemblies and AMS feeders. We work out what is worth holding on your own shelf and at roughly what rate you will get through it, so a print is not waiting three days on a courier.
Heavy work — plate replacement, hotend swaps, full strip-and-clean — scheduled into holidays, shutdowns or quiet weeks, so the machines are at their most reliable exactly when students or deadlines are hammering them.
Machines bought in different years by different people, in wildly different states of neglect, with no maintenance record between them. We baseline the lot, document what is actually in the room, and bring it to a known standard.
Simple steps to get your problem solved quickly and professionally.
How many machines, which models, where they live, how hard they are worked and who currently looks after them. For most sites that is a phone call and a list. For larger or more complicated fleets we would rather come and look before quoting anything.
The first pass brings every machine to a known state. This is where inherited neglect surfaces — worn plates, cooked hotends, PTFE nobody has changed — so we treat it as its own piece of work and quote it separately from the ongoing arrangement, rather than burying a surprise in a contract.
You get the written picture: what was done to each machine, what is worn, what to budget for and when. That is the document a bursar, business manager or studio director can actually approve against, instead of a repair invoice arriving unannounced.
We fit the cycle to your year — term dates, exam and project deadlines, production runs, shutdown weeks — and work to it. Reviewed as machines join, leave or change how they are used.

Per-incident repair works fine for one printer at home. It fails badly across a fleet, because the machines wear at roughly the same rate and therefore tend to fail at roughly the same time — usually the week everyone needs them. Planned servicing breaks that pattern by staggering the work deliberately.
Fleet size changes what makes sense. Three machines in one room is a different exercise to fifteen across three buildings, which is exactly why we scope before quoting.
We do not publish contract pricing, because a number that fits a three-printer studio in Fulham would be wrong for a college running twelve machines in Yorkshire. What we do instead is scope the fleet and put a written quote in front of you, with the ongoing arrangement and any one-off baseline work costed separately so you can see what you are actually buying.
Written quote before anything starts
Scoped to your fleet and put in writing, so it can go to a bursar, business manager, finance lead or studio director for approval rather than being agreed verbally on site.
Invoiced on your terms
We invoice institutions and companies in the normal way. If your finance office needs a purchase order referenced, or supplier details set up before work can begin, tell us at quote stage.
Baseline work priced separately
An inherited fleet usually needs remedial work before a maintenance rhythm makes any sense. We quote that as its own job so the recurring cost is not inflated by a one-off catch-up.
Reviewed, not locked and forgotten
Fleets change. Machines get added, retired or moved between rooms. The schedule and the scope get revisited rather than rolling on unchanged.
Procurement requirements vary enormously between schools, universities and companies. If there is specific paperwork, vetting or supplier onboarding you need before you can engage anyone, raise it with us at the quote stage so nobody wastes time.
We are workshop-based at 66 Lower Richmond Road in Putney, SW15. Being straight about geography matters more than sounding bigger than we are, so here is exactly what each option looks like.
Onsite — London and the South East
Where we can realistically get a technician to you and back in a day. Best for fleets that are awkward to move, heavy enclosed machines, or sites where printers cannot leave the building.
Free collection and return — South West London
Across our South West London service area we collect and return at no charge. Practical when a machine needs bench time rather than a quick fix in situ.
Courier-in — anywhere in the UK
Printers come to the Putney workshop by courier and go back the same way. Carriage is arranged and costed as part of the job rather than being free, and heavier enclosed machines need proper packaging to survive the trip.
Remote diagnosis — anywhere
A surprising share of feed, calibration and profile faults are resolvable over a call with someone standing at the machine. For sites with their own technician this is often the fastest route and the one we reach for first.
We do not claim national onsite coverage, because we do not have it. If you are outside the South East, the honest answer is a mix of remote support, courier-in work and planning that keeps you off the back foot in the first place.
The reason organisations end up firefighting is rarely incompetence — it is that nobody has a written picture of the fleet, so every failure arrives as a surprise and gets funded as an emergency. The condition report exists to fix that.
Where a machine is genuinely at the end of its useful life we will say so rather than quoting another repair. Telling a school to keep spending on a printer that should be retired is not a service.
A very common starting point: someone has left, or a department has absorbed machines from elsewhere, and what remains is a room of printers with no maintenance history, no consistent profiles and at least one machine everybody has quietly given up on. That is a normal job, not an embarrassing one.
Baseline work is quoted separately from any ongoing arrangement, so you can take the catch-up now and decide about a rolling contract afterwards.
