Lovely work, a pleasure to read through your thread. 

It's been a couple of months since my last update.  I spent most of February finishing up my Hannah SIB build, and then have been busy with work, kids, etc.  
 
This week I did take some time to continue filling and sanding the hull, and installed the stern counter.  When I looked at the NMM plans for the Pegasus, the counter seems to be a little more curved than the supports with the kit.  So, I sanded back the stern extensions to add more of a curve, thinned down the stern counter a bit, soaked it and let it dry against a thermos, and then installed it yesterday.  It probably could have been curved a bit more, but I think it works.  The curves won't be as apparent once the decorative pieces are installed anyway.  I plan on planking over the walnut ply piece with some thin pear.
 

 

 
 
I'll start the second planking soon.  I want to take the time to line the hull the right way, as I'm planning on using multiple colors for the upper hull planking.  The base color will be pear stained a darker brown color.  Then I will use pear stained blue for the frieze area, followed by redheart planking for the top area of the hull.  The wales will be pear stained black, and I'm thinking of using black for the area between the wales and the coppering, which I think looks great on Realworkingsailor's build.  A lot to plan out when using stains, but hopefully with a little pre-planning all should go well.

Here's some of the progress today. I've put some higher res images here compared to the last so you can have a better look (without too much eye squinting). I wanted to do some tests to see how the quality was after a coat of paint. I was suprised that it had such a good surface without any sanding or work done to it (par clipping), I had thought the slight residue that was left might prohibit a nice coat. They were sprayed with cellulose paint (they are just testers, so don't worry about my colour choices).
 
They are all printed 0.05mm apart form the red one which was done at 0.1mm. Detail does look more dull, but the trade off is it takes half the amount of time. It took 4h20mins for 9 cannons at medium detail (0.05mm)
 
I went further adding a coat of high gloss to see if it could pick up and reflect any imperfections in the print - very little stood out.

The print is angled as the machine likes to print on a skewed orientation. That's what result in so much support structure (basically a sprue as you mentioned). Handily you can set the point size so that they can easily snap off however. An alternative (and probably wiser) way would be to print the model in several parts as dvm suggested. 
 
The reason the machine prints skewed, is just a result the way the printer functions. I believe this is due to the 'peeling' process that is involved with the bed. Each time a laser shoots towards the bed (the plate that holds the resin) it tilts downwards, allowing the model to peel off. The plate holding the model then moves upwards, and the same process then happens again. If I remember right that model was about 700 'peels' 
 
On high resolution (0.025mm) it'll take 4h20. Quite a drastic difference in time. Maybe I'll get a chance this week to give it a try and compare surface quality between the 3.

hey druxey, 
 
yeah they are all resin based - there aren't many materials available unfortunately. They have the standard resins with different colours, a 'castable' resin (wax based) used for investment casting in jewlery and a flexible resin. But that's it. That is one of the downsides with this machine.

I thought I'd add a post/log here of my experience testing with the Form1+ printer. I've had a fair amount of experience with different 3D printers so I'll document my ramblings and it may be of some use to someone, who knows? The university recently bought a Form1+, and since I'm the printing nerd they've given it to me to set it up (and play with). We have access to a whole range of different FDM printers in the studio but they are all junk for creating very detailed parts. They are good for objects with large surface area and some other parts, but the amount of sanding and filling is their downfall - even with a coat of XTC.  
 
So the machine arrived today and I spent most of the day setting it up. I'll be busy getting all my CAD files ready for printing and I'll get a whole batch on tomorrow. From the first try, the machine prints very well and is incredibly easy to setup (compared to some others). Simple and fast to operate it certainly gives some commercial machines a run for their money. With the machine costing less than a 1/10th of the professional ones the quality loss isn't drastic either. 
 
My test print cannon is at a 1:64 scale just over 4cm in length. Printed at 0.05 mm (which translates into medium settings for the machine) took 2 hours to print. Cost came to £1 (matieral wise) using just under 10ml of resin. However cost of consumables would have to be added (the printing tray and the alchol solution).

I've taken a keen interest in the 3D printing movement and followed it continuously. I want to try using it to create the detail on the captains cabin and several other smaller details. I've used the Form1 desktop printer to print a section of the mary rose on a previous project at a 1:200 scale. I don't have any closer photo's unfortunately, but it came out very well. 
 
Check out this link, some interesting work being done there.
