| Version | 0.1 DRAFT FOR REVIEW |
| Effective (target) | 09/10/2026 |
| Owner | Lab Technician (process) / Doctor (clinical release) |
| Stack | Pro 2 (primary); resin handling per SOP-LAB-001 |

Related: SOP-LAB-001 (resin/IPA/PPE); product fabrication SOPs
1. Purpose
Keep the Smile Avenue SprintRay Pro 2 clean, optically clear, and software-current so print quality stays consistent and failures are caught before cases are ruined.
2. Scope
In scope: Build platform care; resin tank inspect/clean/replace criteria; UV lid / hood habits; Optical Panel cleaning; resin handling on the printer; software updates; when to stop and escalate.
Out of scope: RayWare design; ProWash S / NanoCure (see 011 / 012); annual ProTection remote maintenance videos beyond routine lab care (VERIFY if practice is enrolled in ProTection / annual remote maintenance).
3. Who
| Role | Responsibility |
|---|---|
| Lab Technician | Daily/weekly/monthly care; first-line troubleshooting; log tank liters / replacements (VERIFY log) |
| Trainer / Lead Lab Technician | Spot-check Optical Panel and tank condition; competency |
| Doctor | Authorize tank/platform/Optical Panel replacement spend; clinical remake decisions |
4. Safety
- Follow SOP-LAB-001 PPE for all open-resin and IPA work.
- IPA ≥91% on soft towels only — never pour IPA into the resin tank (can damage the film).
- Never put metal scrapers or the print-removal tool into the resin tank. Only resin, silicone wiper, gloved hand, and build platform belong in the tank.
- Do not touch the lens beneath the Optical Panel.
- Keep the red UV hood closed when not accessing the build area.
- Damaged build platform: do not use — can damage the tank and cause spills.
5. Materials
| Item | Notes |
|---|---|
| IPA ≥91% | Soft non-abrasive cloth / soft shop towel |
| Glass cleaner | For Optical Panel second wipe (SprintRay Optical Panel guide) |
| Print removal tool / scraper | Platform only — never into tank |
| Silicone resin wiper | Tank agitation / leveling as needed |
| ~200 µm mesh filter | When emptying tank back to bottle |
| Replacement resin tank | When worn (see replace criteria) |
| Flashlight / phone light | Low-angle tank inspection |
Note on “filters”: SprintRay’s published Pro 2 maintenance set emphasizes resin mesh filtration when emptying tanks and a clear Optical Panel / tank film light path. An onboard air filter replacement cadence was not found in SprintRay Support articles reviewed for this draft — mark VERIFY if hardware has a user-serviceable air filter.
6. Steps by cadence
SprintRay documents event-based tank and optical cleaning (debris, failures, storage) more than fixed calendar intervals. Cadences below are practice operating rhythm aligned to official how-to steps. Items without an official calendar interval are marked VERIFY.
6.1 DAILY (or after each print session)
- PPE on (SOP-LAB-001).
- After print — remove platform first (reduces cleanup): unlock magnetic lock (knob), pull platform toward you; set on protected surface.
- Clean build platform: scrape hardened residue; spray/wipe with IPA ≥91% and soft cloth until no debris. Confirm clean, dry, undamaged surface before next lock-in.
- Resin tank cover: If finished printing for the day, install the resin tank lid/cover to preserve resin (Quick Start / setup guidance).
- UV lid: Use the ergonomic handle; wipe handle with IPA ≥91% if contaminated. Keep hood closed when idle.
- Resin level: Confirm between min and max before next job; top up only after shake per SOP-LAB-001.
- Quick tank look: No cured chunks, no foreign objects, no tank cover left on during a print (never print with tank cover on).
- Spills: Wipe immediately with IPA; do not leave resin on hood, cradle, or Optical Panel area.
- End of day: Platform clean or staged clean; tank covered; hood closed; no open IPA towels left on printer.
6.2 WEEKLY (VERIFY exact weekday — suggested: same day each week)
Perform even if no obvious failure:
- Inspect resin tank film (top and underside) with bright light at a low angle for haze, streaks, cured spots, dust.
- Clean resin tank when residue, long idle resin, partial cures, or print issues appear — and at least weekly if the tank has been in active use (VERIFY if weekly is too frequent for low-volume weeks; SprintRay “when to clean” is condition-based):
- Unlock tank (pull toward you) and lift from cradle.
- Pour resin back to same bottle through ~200 µm filter.
- Gently peel cured chunks — no sharp tools.
- Moisten soft towel with IPA ≥91%; gently wipe inside; avoid pressure on film edges; do not pour IPA into tank.
- Wipe underside clear window thoroughly, including corners.
- Re-inspect with low-angle light; reinstall only when clear and dry. - Clean Optical Panel (top surface only):
- Inspect for fingerprints, dust, resin.
- IPA 91% on soft cloth → gentle wipe.
- Glass cleaner on a separate cloth → remove streaks.
- Fully dry before printing.
- Never touch internal lens; no abrasives; no excessive pressure. - Exterior / lid handle: Soft towel + IPA as needed; no solvents on unapproved surfaces.
- Software check: Settings → Software → confirm Automatic Updates On; install available update if present (do not power off during install).
6.3 MONTHLY (VERIFY — no official “monthly” checklist published; align to practice calendar)
- Tank life review: SprintRay rates tanks up to ~15 L under normal use and recommends replacement after ~10 L for best results. Log cumulative liters / replace date (VERIFY how Smile Avenue tracks liters — RayWare/tank UI vs manual log).
- Replace tank early if any: hazy/scratched/rough film; wrinkles/stretch; loud peeling during print; horizontal lines/shift; poor platform adhesion; visible leaks/discoloration.
- Platform inspection: Flatness, gouges, damaged coating — remove from service if damaged.
- Optical Panel health: Persistent distortion after cleaning, deep scratches, or printer notification → plan replacement per SprintRay Optical Panel article (user-replaceable when prompted).
- Confirm one-tank-per-resin labeling still matches inventory.
- Review open SprintRay Support tickets / recurring fail modes with Lead Lab Technician.
6.4 Resin handling on the printer (every job)
- Shake bottle 1 minute (SOP-LAB-001).
- Assign correct material/shade to tank on touchscreen.
- Platform locked (magnetic knob) before start.
- Nothing on platform except the intended print.
- After failure: clean tank and optical path before reprint (see Troubleshooting).
7. QC
| Cadence | QC check |
|---|---|
| Daily | Platform clean/dry; tank covered when idle; hood closed; resin within min/max |
| Weekly | Tank film clear under low-angle light; Optical Panel streak-free; software current or update queued |
| Monthly | Tank liter/age reviewed; damaged tanks/platforms quarantined |
8. Troubleshooting
| Symptom | First actions |
|---|---|
| Nothing sticks / partial prints | Clean tank (filter resin, wipe film + underside); clean Optical Panel; confirm resin profile matches tank; retry small test |
| Contaminated optical path | Clean tank underside + Optical Panel per guides |
| Loud peel / lines / leaks | Inspect tank wear → replace tank |
| Platform damage | Stop using platform; escalate replacement |
| Software / UI oddities | Check network; run update; reboot only after jobs complete |
| Spill into cradle / panel area | PPE; IPA wipe; do not print until optical path verified clean |
9. Escalate
| Escalate to | When |
|---|---|
| Doctor | Case remakes, patient-delivery impact, capital replacement approval |
| SprintRay Support — 1-800-914-8004 | Failures after tank + Optical Panel clean; Optical Panel replacement prompts; hardware errors; unclear tank/platform damage; software install failures |

11. VERIFY list
- Weekly cleaning weekday and owner initials log.
- Whether monthly cadence should be calendar-fixed or “every 20 print days.”
- How tank liters are tracked (UI vs spreadsheet).
- ProTection / annual remote maintenance enrollment and whether annual video checklist is mandatory on top of this SOP.
- User-serviceable air filter — confirm none, or add official interval if SprintRay documents one for this serial.
- Spare tank / platform / Optical Panel on-hand par levels.
