I will be giving away 3d printed barrels to any model railroader who stops by my table at the Maker Faire KC this weekend. Table 129. I have both wood and steel in HO, S and O scale.
Most of the time, I prime the ABS, as it is porous from the printing process. Here are all three scales, and both wood and steel. I print four at a time, just to keep the cycle time down, and two open and two closed in each group.
O (1/48) scale, as I finished them.
S (1/64) scale
HO (1/87) scale
You can click on the pictures, and see a higher resolution, close up picture. Then you can see the flaws in the FDM printing process. However, at normal viewing distance, for scenic items, they look fine for most purposes. I would not want to use this process for printing motive power or for vehicles. For that I would want an SLA printer at the very least.
