“I’m standing here in pieces and you’re having delusions of grandeur!”

As I’m using 3D-printed parts for the vast majority of the upgrade to this kit, I should probably talk a bit about the nuances of working with the different 3D-print media. And since I’ve just received the new, screen accurate landing bay doors and feet, now’s as good a time as any.

All of the parts I’m using have come from a Shapeways vendor known as 308bits. If you’re unfamiliar with Shapeways, it’s a 3D-printing on-demand service and marketplace. You can upload your own designs and have them printed in your choice from a huge range of media, from versatile plastics through to steel and cast metals; the price depends on the media. Almost all of the parts have been printed in what’s referred to as “Smooth Fine Detail Plastic” which is a translucent, acrylic based media.

Working with this material is a bit different to working with polystyrene or resins. For a start, it is brittle and hard; drilling and cutting requires patience and care. Drilling needs a high speed Dremel or similar – no hand drilling here. And particular care needs to be exercised when removing parts from sprue; they can break easily. Each piece needs to be prepared before any paint or glue, unless you fancy a messy glop that’ll never dry!

I usually start by washing each piece in alcohol (Methylated Spirits or rubbing alcohol) to remove any oils left behind during printing, and allow them to dry for at least 10-15 mins.

Usually, no sanding is required, except where sprue has been cut away. As the media is quite hard, I find the best results come from using jeweller’s files, or emery boards. However in the case of the new landing gear, the struts are quite a bit longer than the stock parts and will require trimming to level out the landing gear.

Original MPC gear on the left is shorter than the new set. After careful measurement, I’ve trimmed them by about 4mm.

Next is a coat of Tamiya Surface Primer. This is compatible with the plastic, and provides a good surface for paints.

The new parts are then painted. Originally when I built the kit, I was a High School student with a very tight budget. So the hull pieces were left with no base coat, and only detail painting of certain areas. Additionally, because it was a team effort, my friend and I each painted a hull piece; so the top half (mine) was quite different from the bottom half (his). I was never really happy about how that looked. After much agonizing, I made the decision to scrap the bottom hull, spray over the top hull and start again. I’ve now resprayed the hull pieces using Tamiya Insignia White. This gives a slightly warm white base that’s easy to match.

The MPC kit not only had only 3 sets of landing gear, the landing gear bay doors were a real guess.

The front doors opened fore and aft; originally I’d modified these by gluing them together and re cutting them to open out to the sides:

Then I got wind of a new set of screen accurate doors from 308bits. While they’re non-functional, they do have the bi-fold door on one side. They just require the removal of the original doors and filling of the hinge-holes. The new units drop into place with a small amount of filing to achieve a smooth fit.

After carefully removing the existing bay doors, I checked each door unit for fit. I found that I had to file out a small amount of material from the internal gear bays to allow the frame of these doors to slip in and fit snugly. A primer coat and a couple of quick coats of Insignia White and they really look the part.
