3Dresyn PEEK‑like vs. “Strongest” SLA 3D resins

Mechanical Resistance Comparison & Executive Summary

Across the selected high-strength photopolymers listed on this page, 3Dresyn PEEK-like is presented using a balance of flexural strength, impact toughness, density, heat performance and open-system compatibility. The comparison is limited to the products and manufacturer-reported data cited below and is not a market-wide “strongest” ranking.

• Reported flexural strength: 120-140 MPa under the stated 3Dresyn test conditions.
• High impact toughness: >30 J/m, helping reduce cracking and chipping.
• Low density: ~1.0-1.1 g/cm³, relevant when comparing specific strength-to-weight metrics.
• High heat performance: HDT >110 °C @ 1.8 MPa and >120 °C @ 0.45 MPa.
• Open-system compatibility: 385/405 nm SLA, DLP, LCD and MSLA printers.

3Dresyn PEEK-like combines reported flexural strength, impact toughness, low density, heat performance and open-system compatibility. These attributes should be compared with alternative materials using matched test methods, specimen conditioning and post-cure conditions rather than by headline MPa alone.

Impact toughness and density may be relevant to brittle-failure risk and part weight, but comparative failure rates cannot be inferred without like-for-like testing on representative parts.

Data Table - Flexural Strength & Key Traits

Post-cure values are compared using the manufacturer data cited below. The comparison universe is limited to the listed products and does not establish a market-wide ranking. Some materials report maximum flexural strength while others report stress at fixed strain, and post-cure/thermal-bake conditions differ; normalise test method, specimen and post-cure before drawing direct performance conclusions.

Mobile: scroll horizontally to view all columns; the resin column remains sticky. Note on comparability: some brands report stress at fixed strain, for example 5%, rather than maximum flexural strength. Several headline values require thermal post-cure. Normalise test method and post-cure when comparing.

Where 3Dresyn PEEK-like may fit

1. Mechanical Resistance in Real Parts

• Reported impact toughness is >30 J/m notched Izod under the stated 3Dresyn conditions. Compare this value only with data obtained using the same or an appropriately normalised method.
• With reported density of ~1.0-1.1 g/cm³, PEEK-like can be assessed using specific flexural-strength calculations. Any claim that it rivals or exceeds another composite requires matched density and flexural data under comparable conditions.

2. Heat + Durability, Not Just Stiffness

• HDT >110 °C @ 1.8 MPa supports loaded parts at elevated temperatures, relevant for tooling near motors, enclosures and thermal cycling.

3. Open-System Compatibility & Process Agility

• PEEK-like is designed for open 385/405 nm SLA, DLP, LCD and MSLA workflows. Some materials in the comparison are tied to proprietary or partner-specific platforms; confirm current printer compatibility with each manufacturer.

Application Guidance

• Functional housings, snap-fits and fixtures with shock or assembly loads: choose 3Dresyn PEEK-like for strength, toughness and heat resistance.
• Wind-tunnel models, ultra-stiff jigs and high-modulus inserts: consider Composite-X, Accura HPC, CeraMAX, Bluestone or Rigid 10K when stiffness dominates and brittleness can be mitigated by design.
• Very high-temperature exposures: xPEEK147, CE221, Loctite 3955 and RG 3280 may offer extreme HDT; check printer access, brittleness and post-cure requirements.
