Paint and Glue Miniatures offer a number of 3D printed vehicles for most of the nations who fought during World War Two.
The models are made to order, and can be re-sized from 1/56th to any other scales. Unlike many similar products, these are created using polylactic acid or PLA, which is made from corn starch and sugar cane. Consequently, they can be considered biodegradable, and manage to be ready for the painting table from the moment you unpack them.
The vehicles sent for review provide a nice cross-section of those currently available.
We have armour in the form of a 1/56th Japanese Chi-Ha tank:

Next we have a Kurogane Type 95 Staff car, in the same 1/56th:

Moving to infantry transport and support, we have a 1/56th German Sd. Kfz. 250-D/20 with Infrared Searchlight, a specialist halftrack:




Lastly, we have a 1/100th scale Chi-Ha tank, demonstrating one of the alternate scale options available.




There are around 100 models so far, with plans to reach 300 in the future. These are either designed in-house, or are produced under licence from other designers. Final price depend upon the scale required, but the 1/56th prices on the website are very reasonable. These appear to be accurately sculpted miniatures, with suitable proportions, and are durable enough to survive most tabletops, whilst having the same or lesser weight than plastic kits. Well worth a look, and environmentally friendly to boot!
