When a 3D print begins with an uneven or poorly attached first layer, a service request needs more than the conclusion “the printer is broken.” A clear intake separates what the operator observed, which machine and material were involved, and which changes had occurred before the problem. That information can help the service provider decide what to ask next.
Record where the first-layer issue appeared, whether the material failed to adhere, whether lines looked uneven, and whether the issue occurred across the whole surface or only in one area. Note the time, machine model, software version, material and print surface if known. If any detail is uncertain, say so rather than filling it in from memory.
Pictures can help a technician understand the pattern, but they must be labelled with the print attempt and viewing angle. The site’s guide to reference points in service photographs explains why before-and-after images need context. A photo by itself does not establish the exact nozzle distance, the measurement accuracy or the cause of an adhesion problem.
Prusa’s first-layer calibration article discusses nozzle distance and first-layer appearance for the product families identified on that page. It also notes that adhesion issues can have other causes. The page is a source for those specific products and procedures; it is not a universal instruction for every printer, material or print surface.
The service request should identify which manufacturer documentation, if any, was consulted. If the machine is a different model, ask the relevant manufacturer or service provider for its applicable instructions. Do not copy calibration values or disassembly steps from another model merely because the visible result looks similar.
List changes that occurred before the observation, such as a new material spool, a different removable sheet, a software update or a move to a new location. Distinguish a confirmed change from something that is only suspected. If the change date is unknown, leave it as unknown. A change and a later issue can be related, but their timing alone does not establish a cause.
For a hypothetical example, suppose a user changed the print surface and later saw an uneven first layer. The user can provide the surface type, machine model, print file and pictures from the affected attempt. A technician may then request further evidence. The example does not establish that the new surface caused the problem or that a particular adjustment will solve it.
A part that lifts at its edges may be described differently from a first-layer line that appears inconsistent. Prusa’s warping information discusses warping and relevant factors for its printing context. Record whether lifting was observed during the initial layer or later in the build, and identify the area affected where possible.
These observations can occur together, but a service ticket should not combine them into one unverified root cause. Avoid assigning a failed component based solely on the shape of the print. The manufacturer or qualified technician can decide which checks are appropriate for the exact device and conditions.
Ask the service provider which files are needed, such as a print configuration, the model file or a machine log, and which sharing method is approved. Note whether the file is the one used in the failed attempt or a later edited copy. Preserve relevant version information where available. Remove or protect unrelated customer designs, account details and other sensitive information before sharing, according to the owner’s policy.
If an attempt was stopped early, state that explicitly. A partial print and a completed print are different observations. If the machine showed smoke, damaged wiring or another unsafe condition, stop using it and follow the manufacturer’s and site’s safety procedures rather than running further tests to complete a report.
A useful request contains the contact method, device identity, observed symptoms, relevant changes, attached evidence and a list of what remains unknown. Record what the service provider asks for and what was actually supplied. If a later test is authorised, preserve the conditions and its result alongside the original report so the technician can compare them. Do not mark a repair as completed merely because an article or remote suggestion was received.
The industry information section provides related background. Any calibration, maintenance or return to service should follow the correct product manual, the service provider’s instructions and the site’s safety process for the actual machine.
