This is a realistic concrete guardrail 3D model, designed for easy and reliable 3D printing.The model is optimized for both resin (SLA/MSLA) and filament (FDM) printers, making it suitable for beginners and experienced users.
Perfect for:DioramasArchitecture visualizationRoad, highway, or urban scenesScale models and propsThe geometry is clean, solid, and balanced to avoid fragile areas, reducing the risk of cracks or breaks after printing.

Resin Printing (Halot Box – Beginner Friendly)Global Settings
Layer Thickness: 0.05 mm(Best balance between detail and strength)
Rising Height (Z Lift Distance): 5 mm(Helps prevent layer separation)
Motor Speed (Lifting Speed): 3 mm/min(Slow = safer, less breakage)
Light-off Delay: 2.0 s(Allows resin to settle, reduces failures)
Bottom Part
Initial Exposure Time: 30 sBottom Layer Count: 5 layers(Strong adhesion, avoids detaching)
Regular PartExposure Time: 2.5 s(Safe for most standard resins)Resin Tips (Very Important)Print slightly tilted (10–15°)Use medium supports, avoid ultra-thin tipsWash gently in IPA (do not scrub hard)Cure slowly to avoid brittleness
EXTRA TO PREVENT BREAKING
Use medium supports, not thin onesTilt the model 10–15°Do not wash aggressivelyCure under UV gradually (over-curing makes it brittle)
Filament Printing (FDM – PLA / PLA+)Recommended Filament
PLA or PLA+ (PLA+ is stronger and less brittle)
Print Settings
Layer Height: 0.2 mm
Nozzle: 0.4 mm
Wall Thickness: 1.6 mm (4 walls)
Infill: 20% (Gyroid or Grid)
Print Speed: 40 mm/s(Slower = stronger)
Temperatures
Nozzle Temperature: 200–210 °C
Bed Temperature: 60 °C
Cooling
Fan Speed: 80%(Too much cooling can cause cracks)
FDM Tips
Print flat on the bed
Avoid very thin scaling
Do not exceed 60 mm/s speed
Let the model cool naturally before removing
