What is in a 3D printing material datasheet?
Mechanical, thermal and physical property data for a printed grade: tensile strength and modulus, elongation at break, flexural properties, notched impact, heat deflection temperature, density and moisture absorption. Each figure carries the ISO or ASTM test method it was measured to, and values are published for both XY and Z print directions where the process produces a meaningful difference.
Why are XY and Z values different on the same material?
Because a printed part is anisotropic. Material is deposited or fused layer by layer, so strength along the layers (XY) is higher than strength across them (Z), and in fibre-reinforced grades the fibres align with the print direction, widening the gap further. Design against the Z figure unless you can guarantee the orientation, and tell us the load direction at quote so we can orient the build to suit.
Is this RYSE 3D test data or the manufacturer’s?
The property values originate from the manufacturer’s technical data sheet for each grade, reproduced with the test method and, where relevant, the print direction and cure condition stated. We publish them in a consistent format so grades can be compared like for like. Where our own experience of a grade differs from the published figure in practice, we say so on the material page rather than quietly adjusting the number.
Will my part actually hit the datasheet numbers?
Treat datasheet values as a benchmark from standard test specimens, not a guarantee for your geometry. Real parts are affected by orientation, wall thickness, infill, layer adhesion, post-processing, cure state and service conditions such as temperature and moisture. Design with margin, and for anything load-bearing or safety-related, test the actual part rather than trusting the sheet.
Can I compare impact figures between SLS, MJF, FDM and SLA?
No, and this is the most common mistake we see. SLS grades quote notched Izod to ASTM D256-10 in J/m, MJF grades quote notched Izod to ASTM D256 in kJ/m², FDM grades quote notched Charpy to ISO 179 in kJ/m², SLA grades quote notched Izod to ASTM D256-10 in J/m, and PA12-CF uses notched Izod to ISO 180. Some share a unit without sharing a method. Compare within a process only, or ask us.
Does a UL 94 V-0 rating apply to my part?
Only at the thickness it was tested at. Our SLA Flame-Retardant resin achieves UL 94 V-0 at 3 mm, V-1 at 2.5 mm and HB at 1.5 mm, so a thin wall does not carry the headline rating. It also passes FAR 25.853 vertical burn at 2.5 mm. Design to the thickness you need the rating at, and tell us at quote if a specific certification route has to be satisfied — we will be straight about what the material does and does not cover.
What tolerance can you hold on a printed part?
Our standard tolerance is ±0.3 mm for parts up to 100 mm in size. For larger dimensions it is generally calculated as ±0.3 mm for the first 100 mm, plus an additional ±0.1% for every 100 mm thereafter. Tighter fits, bores and sealing faces are achieved by printing near-net and machining the critical features — full detail on the
tolerances and accuracy page.
