Both are almost same, just the meaning is different like 3D pipe bend means three times the Diameter, and 3R Bend or Elbow meaning three times the Radius. The main difference between 3D elbow vs 3R bend is bending radii. As a result 3R bends have a smoother bend and 3D pipe bends have a sharper bend.
A 3D bend has a bend radius that is three times the pipe's outside diameter, for example if 3d bend is used in 8 inch pipeline, then the bending radius would be 24 inches
Here is an example to check the material factor between different alloys

Bend Allowance (BA)
Formula:
[(0.017453 × Inside radius) + (0.0078 × Material thickness)] × Complementary bend angle
Outside Setback (OSSB)
Formula:
[Tangent (Degree of bend angle / 2)] × (Inside bend radius + Material thickness)
Bend Deduction (BD)
Formula:
(Outside setback × 2) – Bend allowance
There are two different ways for flat blank calculations which are
Generally, 3D pipe bends are marked to show below details, make sure marking should not be deep enough or sharp enough to cause crack or reduce wall thickness
Outer diamete(D) | Wall thickness(T) | Straight Length (L) |

D≤1800mm | T≤120mm | 300mm-1500mm |
Bevel ends are prepared as per ASME B16.25 Standards. It can be cut square or slight chamfer, at manufacturer’s option:
