Every month, we shout out the most helpful members of #PrintClinic — the ones who give clear, actionable, and friendly advice that actually gets prints unstuck.
Meet this month's 3 Gold Medal Doctors and their standout cases 👇
How We Pick Them (Quality > Quantity)
We're not rewarding reply spam — we're looking for answers that actually fix prints:
✅ Accurate diagnosis — nails the root cause, not just the symptom
✅ Actionable fixes — real settings, real steps, reproducible results
✅ Confirmed fix — the OP (original poster) comes back to say it worked
✅ Beginner-friendly — patient tone, no gatekeeping, no jargon dumps
🏆 This month’s Gold Medal Doctors
🥇 Doctor: @waylaidwanderer
Specialty: Stringing / filament tuning / PETG troubleshooting
June track record: 244 helpful replies · 35 confirmed fixes
Featured case: "PETG keeps leaving little nubs on print walls"
From the photos, those bumps look like PETG oozing during travels and getting deposited back on the surface — not random slicer glitches. Even if you dry often, PETG stays hygroscopic. Try this order:
- Dry it properly first: active dry at 65°C for 6–8 hours in a dedicated dryer — "regular drying" often isn’t enough;
- Lower nozzle temp: try 240–245°C so the material is less runny;
- Slow outer walls: reduce outer-wall speed to ease pressure in the hotend;
- Enable wipe settings: turn on retraction wiping / outer wall wipe in Bambu Studio.
Why they made the list: Asks for details first, then delivers a full PETG oozing playbook with exact temps and slicer toggles — the kind of answer you can follow step by step.
🥈 Doctor: @UltraModern3D
Specialty: First-layer adhesion / bed maintenance / multi-color slicing
June track record: 89 helpful replies · 9 confirmed fixes
Featured case: "Prints detach mid-print — especially articulated models"
When small parts lose grip halfway through, it’s usually a bed adhesion / plate condition issue — not always "wrong settings." Try this order:
- Clean the build plate: wash with warm water + dish soap, rinse, dry fully;
- Flip the plate: use the other side if one face is worn or oily;
- Replace if needed: if cleaning + flipping don’t help, the plate may be done;
- Follow up: OP liked the answer — UltraModern3D always invites questions after the fix.
Why they made the list: Short, on-target, and actionable for the most common adhesion failure path — clean, flip, replace — without overcomplicating it.
🥉 Doctor: @A-A-ron987
Specialty: Model & slicer diagnosis / support strategy / closing the loop
June track record: 19 helpful replies · 11 confirmed fixes
Featured case: "Card stand looks stringy — but is it really stringing?"
From the photos, that area is an extreme overhang — the bundled profile likely shipped without supports, not a retraction/temp issue. Try this order:
- Enable supports in Studio — open the model in Bambu Studio → Quality tab → turn on supports → Slice → Print;
- Follow up after the reprint — areas where supports were removed may not be perfectly smooth; check for a grid pattern — no grid means supports are fully off;
- Skip the purge tower — this print only needs one color change; disable the tower in Studio to save filament.
Why they made the list: Gives click-by-click Studio steps, then follows up after the OP’s result with cleanup + purge-tower tips — textbook closure.
