The 3MF files that we sell are the type of
computer files used to make or "build" 3D printed models in any desired scale.
They are not the models themselves, you will not receive any physical ship
models in the mail. These files are only available as digital downloads through
our online store.
In order to build their own models with these files,
people will generally have their own 3D printer or they know someone who owns
one. The printers with the better abilities to make these models at home are
resin based SLA and DLP units made by companies like 3D Systems, Elegoo,
Phrozen and Anycubic to name a few. The DLP models previously sold in the WTJ
store were made on a 3D Systems Figure 4 machine.
The two files you
receive for each model come in default scales of 1/1800 and 1/1250, either can
be printed in any desired scale by resizing it. The 1/1250 scale will have
standalone gun barrels for the heavier armaments and unsupported tripod masts
(if any). Some of the various vertical features will also be finer and thinner
to look better at larger scales. The 1/1800 scale file will have all gun
barrels fully supported with a solid boss, and all tripod masts will be fully
supported. Some vertical features will also be slightly heavier (thicker) to
help assure proper printing at smaller scales.
Remember that either of
these files can be printed at any scale. It is just that the two sizes have
been tuned somewhat to better match the scales they are likely to be built at.
For example, many people with home printers may not want to risk barrel
distortion or breakage on a 1/2400 scale model, so they might use the well
supported 1/1800 file as their starting point. Others may be experinced
modellers who want that fine gun turret detail and they would use the 1/1250
file as a starting point to make 1/2400 ships. They can get there either way.
Below is a conversion table to help change the default file scale for either
model to any other common scale: |

| Cross reference the
Default File Scale line with the Scale to Build column to find the decimal
multiplier. Use that to change your starting file size to the scale you want to
build. |

| The files we sell are in the latest 3MF
format. We do not sell the STL file format because it takes up too much space
on our servers, and we have a lot of models to sell (over 400 at last count).
Many 3D printers can run 3MF, but for those units that do not accept these
files yet, you can convert 3MF to STL using software platforms like Solidworks
or Magics. There are also several on-line file conversion services such as
Aspose. Please remember that all WTJ Naval digital files are copyright
protected, you can Read Here the terms of use for buying our files and the
copyright protections that cover them. |
