Material Profile: Aqua Hyperfine Resin for SLA / LCD 3D
Phrozen SLA / LCD Resin Technical Report Series
Compiled from Phrozen official datasheets, SDS documents, and third-party technical reviews
Abstract—Aqua Hyperfine is Phrozen's ultra-high-resolution resin designed for 12K-class LCD machines and beyond. The formulation prioritises sub-30 µm feature reproduction over toughness, making it the choice when extreme detail (eyelashes, fabric weave, miniature engravings) is the primary requirement. Low viscosity and low odour facilitate post-processing.
Index Terms—additive manufacturing, SLA, LCD, photopolymer, ultra-high resolution, 12K, hyperfine detail.

II. COMPOSITION AND PHOTOPOLYMER CHEMISTRY
A. General Resin Family
Generic photo-polymerisation: monomers (multi-functional acrylates / urethane-acrylates) + photoinitiator (e.g., TPO / BAPO) + 405 nm UV → crosslinked thermoset network. Exact formulation is proprietary.

Constituent |
Mass fraction |
Function |
|
Multi-functional acrylate monomers (low-viscosity formulation) |
≈ 70–85 wt% |
Form the backbone of the cured network |
|
Reactive diluents (low-viscosity acrylates) |
≈ 10–20 wt% |
Reduce viscosity; increase crosslink density |
|
Photoinitiator (acylphosphine oxide, e.g., TPO) |
≈ 1–3 wt% |
Absorbs 405 nm UV, initiates radical polymerisation |
|
Pigments, stabilisers, additives |
≈ 1–3 wt% |
Color, UV blocker for shelf life, surface flow |

III. MECHANICAL PROPERTIES
Hyperfine resins trade some toughness for resolution. Properties below reflect typical post-cured behaviour; brittle failure is more likely than with toughened resins (RPG, BJD).

IV. RECOMMENDED PRINT PARAMETERS
Values below are the manufacturer-recommended starting points for compatible Phrozen LCD printers; specific machines may require ±10–20% adjustment based on LCD age and ambient temperature.

Notes |
|
UV wavelength |
405 nm |
Standard for Phrozen LCD printers |
|
Compatible printers |
Phrozen 12K-class machines (Sonic Mighty Revo 14K / 16K) and 8K machines |
Best paired with the indicated resolution class |
|
Layer thickness |
0.025–0.050 mm (typical 0.030 mm) |
Thinner layers improve detail at the cost of print time |
|
Normal exposure (per layer) |
≈ 1.5–2.5 s @ 12K; 2.5–4 s @ 8K |
Test-tower validation recommended |
|
Bottom exposure |
≈ 25–35 s × 6 layers |
First-layer adhesion to build plate |
|
Lift distance / speed |
≈ 6–8 mm @ 60–100 mm/min |
Slower for fine geometries |
|
Wash medium |
Isopropyl alcohol (IPA) or 95% ethanol |
30–60 s wash; do not over-soak |
|
Post-cure |
405 nm UV box, 30–120 min depending on size |
Phrozen Cure Mega S or equivalent |
V. GLASS TRANSITION TEMPERATURE (TG)
Reported / typical Tg: ≈ 70–80 °C.
Higher Tg than RPG/BJD resins reflects the higher crosslink density required for fine-feature resolution.
VI. HEAT DEFLECTION TEMPERATURE (HDT)
HDT defines the temperature at which a 1.27 mm-thick standardised bar deflects 0.25 mm under the specified flexural load. Two test loads are reported per ASTM D648 / ISO 75.

VII. DISTINGUISHING CHARACTERISTICS AND STANDARDS
A. Sub-30 µm feature reproduction
Optimised for the sharpest possible feature reproduction on 12K-class LCD panels. Reproduces fabric weave patterns, individual hair strands, and engraved text below 50 µm.
B. Low viscosity (280–380 cP)
Flows easily into deep recesses and supports thin-wall geometries; reduces print failures from incomplete cavity filling.
C. Post-process friendly
Low-odour formulation; cleans easily in IPA or ethanol; minimises hazardous fumes during printing in shared workspaces.
D. Resolution-first trade-off
Lower toughness than RPG / BJD; not recommended for handled or articulated parts. Use for display / collectible models.
VIII. REPRESENTATIVE APPLICATIONS
Aqua Hyperfine Resin is typically deployed in the following applications:
1) Highest-detail collectible figurines: Where extreme face / fabric / texture detail matters more than handling.
2) Engraving and text-heavy models: Architectural inscriptions, plaque models, micro-detail engravings.
3) 12K-era reference prints: Showcase models for 12K printer launches and capability demos.
4) Dental and surgical models (display): High-resolution reference dentition, vascular models for visualisation only.
5) Jewelry master patterns: Ultra-fine details for casting masters and concept verification.
