SprintRay Die & Model 2 and Study Model White 2 — Lab Manufacturing Procedure
| Document ID | SOP-LAB-110 |
| Version | 0.1 DRAFT |
| Effective (target) | 09/10/2026 |
| Owner | Lab Technician (process owner) |
| Status | DRAFT FOR REVIEW |
Start: Case received in Medit Lab with scan QC
End: Model bagged and logged in SEAZONA for outbound delivery (or lab-hold for thermoform / wax-up use)
1. Purpose
This procedure standardizes in-house printing of SprintRay dental models (Die & Model 2 and Study Model White 2) for study, aligner/retainer thermoform masters, bleaching trays, and wax-ups.
2. Scope
In scope: Medit Lab intake → scan QC → model design/export (VERIFY path) → RayWare / Pro 2 → ProWash S → NanoCure → finish clean → bag & SEAZONA (or documented lab hold).
Out of scope: Patient-worn appliances printed on these resins (models are not definitive intraoral devices beyond IFU model uses); direct-print retainers (SOP-LAB-080); non-SprintRay printers.
3. Roles
| Role | Responsibility |
|---|---|
| Clinical Assistant / Office | Sends case via Medit Lab; receives bagged model when outbound |
| Lab Technician | Scan QC; design approve; print; wash; cure; clean; bag/hold; SEAZONA |
| Trainer / Lead Lab Technician | Competency observation and sign-off |
| Doctor | Indication / model purpose; remake authorization |
4. Practice Configuration
| # | Item | Smile Avenue setting |
|---|---|---|
| 1 | Printer | Pro 2 only for this path |
| 2 | Resins | Die & Model 2 or Study Model White 2 per Rx / purpose |
| 3 | Cure unit | NanoCure — exact Die & Model 2 or Study Model White 2 profile |
| 4 | Case intake | Medit Lab |
| 5 | Design | VERIFY — outside CAD or SprintRay Cloud Design / model builder |
| 6 | Wash | ProWash S — IPA ≥ 91% — standard preprogrammed cycle |
| 7 | Layer thickness | Typically 100 µm default |
| 8 | Orientation | Intaglio / anatomy facing away from platform (accuracy) |
| 9 | Design approval before print | Lab Technician |
| 10 | Case log | SEAZONA |
5. Safety
- Treat uncured model resins as sensitizers. PPE + ventilation.
- Do not use for indications outside IFU model uses. Do not place incompletely cured resin intraorally.
- Cure waste resin fully. Do not use expired resin.
6. Materials & Equipment
| Resin | Typical use |
|---|---|
| Die & Model 2 | Dies, precision models, thermoform masters |
| Study Model White 2 | Study / presentation / thermoform masters (white) |
Equipment: Medit Lab → design (VERIFY) → RayWare → Pro 2 → ProWash S → NanoCure → SEAZONA.
7. Process Controls
| Gate | Do not proceed if | Proceed when |
|---|---|---|
| Design | Not approved / wrong resin for purpose | QC-A pass |
| Printer | Not Pro 2 | Pro 2 |
| Pre-cure | Wet | Fully dry |
| Cure | Wrong profile | Exact Die & Model 2 or Study Model White 2 complete |
| Outbound / hold | Failed QC-E | Bagged or documented lab-hold in SEAZONA |
8. Procedure
A. Intake & scan QC
- Medit Lab: verify ID, arch(es), model purpose (study / thermoform / die / wax-up), resin choice, due date.
- QC-SCAN.
B. Design (VERIFY)
- Create/receive model STL; hollow/base settings per practice (VERIFY hollow defaults).
- Lab Technician approves. QC-A: Purpose match; resin noted; STL labeled.
C. Nest
- Model appliance type; Die & Model 2 or Study Model White 2; anatomy away from platform; ~100 µm; default supports; Pro 2.
D. Print
- Shake 1 minute; pour; assign shade/material; print; log lot. QC-B.
E. Wash & dry
- ProWash S standard cycle; dry fully. QC-C.
F. Post-cure
- NanoCure Die & Model 2 or Study Model White 2 exact profile. Remove supports. QC-D.
G. Finish, clean, bag / hold
- Soap + brush + warm water; dry.
- Bag for outbound or place in lab hold for thermoform workflow; log status in SEAZONA. QC-E.
End of SOP-LAB-110.
9. Case Log (SEAZONA)
| Field | Entry |
|---|---|
| Date / case ID | |
| Purpose | ☐ Study ☐ Thermoform ☐ Die ☐ Wax-up ☐ Other |
| Resin | ☐ Die & Model 2 ☐ Study Model White 2 + lot |
| Design approved by (Lab Technician) | |
| NanoCure profile | Die & Model 2 ☐ / Study Model White 2 ☐ |
| Disposition | ☐ Bagged outbound ☐ Lab hold |
| QC pass | ☐ Yes |
10. Quality Checkpoints
| ID | When | Pass | Fail action |
|---|---|---|---|
| QC-SCAN | After Medit Lab intake | Scans usable | Return to office |
| QC-A | Pre-print | Approved design + correct resin | Return to design |
| QC-B | Post-print | Complete geometry | Remake print |
| QC-C | Post-wash | Clean + dry | Re-wash/dry |
| QC-D | Post-cure | Fully cured; supports clean | Remake / salvage |
| QC-E | Before outbound / hold | Finish + clean + bag or documented lab-hold + SEAZONA | Hold release |
11. Remake Criteria
| Finding | Action |
|---|---|
| Failed scan QC | Do not manufacture — request new scans |
| Incomplete print / critical voids / delamination | Remake print |
| Printed on non–Pro 2 | Remake on Pro 2 |
| Wrong resin for purpose / wrong NanoCure profile | Hold; correct or remake |
| Light support nubs only | Salvage — finish and re-check QC-E |
| Unsure | Stop and escalate to Doctor / lab lead |
12. Competency
| Requirement | Sign-off |
|---|---|
| Read SOP-LAB-110 | Tech _ Date ___ |
| Demonstrates Die & Model 2 and Study Model White 2 paths | Trainer _ Date ___ |
| Completes 3 observed cases to bagged outbound or documented hold | 1. __ 2. _ 3. ___ |
| Trainer attests ready | Trainer _ Date ___ |
| Lab lead authorizes unsupervised production | _ Date ___ |
13. Troubleshooting & Escalation
| Problem | Action |
|---|---|
| Bad scans | QC-SCAN fail → return to office |
| Print failure | Remake; filter resin; verify material assignment |
| Soft after cure | Confirm dry part and exact Die & Model 2 or Study Model White 2 profile |
| Wrong model resin for thermoform vs study | Confirm Rx; remake if needed |
