Third Time Lucky? - Battledown Flyover #3

These five parts join together to make the bridge deck. It is nearly one metre long. Longer than the sides because the bridge is skewed. 

All but the smallest exhibit a small bow which can be manipulated straight due to the pliability of the resin. Once the sides are glued to the deck I expect the bows to be eliminated.

A couple of printing errors manifested. One was a delamination of print layers, simply due to insufficient support structures. The affected parts will not be reprinted as the fault is not too noticeable.

The other is a little odd. A rippling warp of a girder web. Odd because it only affected one girder on this part.

Earlier I said that in the design I had increased plate thickness to 0.5 mm. In fact I only did this to the sides of the bridge, not the deck because I could not be bothered and accepted the risk.

Fortunately this piece is hidden in the bridge embankment so can be left as is. Having seen this fault though the design of the centre pieces that are visible were increased in thickness before they were printed and they printed perfectly. This proves to my mind that 0.5mm plate thickness is acceptable when using this Anycubic water washable ABS like 3.0 resin.

Third Time Lucky? - Battledown Flyover #2

Here are the parts that make up one side of the bridge, except the three girders at the top span both sides.

So far there have been no breaks or warp using the Anycubic Water Washable ABS Like V3.0 resin. I am particularly pleased that the thin handrails have held their form (1mm diameter) although time will tell if they droop due to gravity like the other resin fabrication did.

Another nice aspect is that the print time is about half that of the other resins I used before. 

The next photo is to show off the rivet detail achievable with this technology. Each rivet is 0.5mm diameter.

The assembled side ready for painting. It is just over half a metre long.
