3D Printer Repair & Servicing in Chelsea | PC Macgicians

We focus on Bambu Lab (A1, P1S, X1 Carbon) and the popular Creality, Prusa, Anycubic and Elegoo consumer printers. If your printer is one of the major FDM brands sold in the UK, we almost certainly cover it. Resin printer repair is more limited and we'll discuss it case-by-case before booking.

Yes — Bambu is our most-requested brand. We handle hotend assembly replacement, AMS feeder faults, PTFE replacement, extruder repair, and the full annual service across the A1, P1 series and X1 series. See our [Bambu Lab repair pages](/services/3d-printer-repair/bambu-lab/) for model-specific detail.

Diagnostic and quote usually within one to two working days of drop-off. A standard hotend or PTFE replacement is often same-day once parts are confirmed in stock. Full annual services typically take half a day on the bench. Complex motion or electronics work can take longer if we need to order specific parts.

Rod and rail cleaning, lubrication of lead screws and bearings, belt tension check, fan health and bearing noise, full firmware update, filament-path inspection including PTFE wear check, build-plate condition assessment, and a verification print of a known calibration model. We send you a written summary of what we found and what was renewed.

Independent repair of a consumable part (PTFE tube, build plate, nozzle) does not void the warranty. Replacing major assemblies during the warranty period is a decision worth thinking through — sometimes a Bambu support ticket is the better route. We'll tell you honestly when warranty support is the smarter option even if it means we don't take the job.

Most repairs run faster and cleaner in our Putney workshop because we have the right tools, parts stock, and a stable bench for calibration. For larger printers, mounted installations or business sites with multiple machines, we can do on-site. Diagnostic visits across SW London are available — call to discuss.

We supply and fit. We keep common Bambu wear parts (hotends, PTFE, AMS internals) in stock for the popular models and order genuine parts from Bambu's UK supply chain for anything we don't carry. You can supply your own part if you prefer, but we won't warranty the part itself in that case — only the labour.

Symptoms that usually mean cleaning and not parts: occasional under-extrusion on the first 100 print hours, mild stringing, intermittent first-layer adhesion. Symptoms that usually mean parts: persistent feed failures with no profile changes, repeated nozzle clogs after a thorough cold pull, AMS HMS_0700 errors that survive a reboot. A diagnostic visit can tell you in 30 minutes.
