3D Printing Material for Long Time Outdoor Use in Opaque Gray Color
Model OP-GY
Mid tone opaque gray, used where the return is meant to be seen as a deliberate colour rather than hidden. A dark return gives an illuminated face a defined edge at night, and grey does that without the harshness of black against a pale building.
- Mid gray gives a lit face a defined edge without the hardness of black
- Opaque through the wall so no light bleeds from the return
- 50 MPa tensile strength supports large returns and mounting points
- Holds its tone outdoors instead of fading towards a chalky finish
Product Overview
Mid tone opaque gray, used where the return is meant to be seen as a deliberate colour rather than hidden. A dark return gives an illuminated face a defined edge at night, and grey does that without the harshness of black against a pale building.
Who It Is For
- Sign makers specifying a visible return colour
- Architects and specifiers working in neutral palettes
- Advertising companies producing dimensional lettering
Problems It Solves
- Black returns can look heavy against a pale facade
- White returns wash out the edge of a lit face at night
- Painted returns chalk and need repainting within a few years
Key Benefits
- Mid gray gives a lit face a defined edge without the hardness of black
- Opaque through the wall so no light bleeds from the return
- 50 MPa tensile strength supports large returns and mounting points
- Holds its tone outdoors instead of fading towards a chalky finish
- Works against both dark and light building surfaces

- Colour checked against the reference sample for each batch
- Each roll vacuum bagged then packed 12 rolls per export carton
Comparison With Other Options
Compared with Opaque light gray
Light gray is chosen to disappear. Mid gray is chosen to be seen and to frame the lit face.
Compared with Opaque black
Black gives maximum contrast but can look heavy on a pale building. Grey softens the edge.
Use Guide
- Pair an opaque gray return with a translucent face colour
- Increase wall thickness at mounting points on large letters
- Print at 230 to 250 degrees and allow the bed to cool before removal
- Keep one batch across a letter set so the grey tone matches
Questions
Frequently Asked Questions
Answers to what buyers ask before ordering 3D Printing Material for Long Time Outdoor Use in Opaque Gray Color.
What is opaque gray used for
Mostly for visible returns and non lit dimensional lettering where a neutral mid tone is wanted.
How strong is the material
50 MPa tensile strength, 68 MPa bending strength and 7.9 KJ per M2 Charpy impact strength.
Will the grey fade outdoors
PETG-S has good UV resistance and is specified for 5 to 10 years of outdoor service.
Should I order one batch for a whole letter set
Yes. Ordering one batch keeps the grey tone consistent across every letter.
What is the minimum order quantity
1 roll for stocked colours. A customised colour has a minimum of 100 rolls.
How is the filament packed for export
Each roll goes into a vacuum bag and 12 rolls are packed per standard export carton, at 440 x 440 x 220 MM.
What warranty applies
One year quality warranty on all products with lifetime technical support.
