As I already said, I will make a comparative post of three oils and will discuss this point too. But I will make a spoiler for you that linseed oil without an ultraviolet filter and in the sun the wood under it can very well darken, I checked this, but more about this later, when I will have delayed results of all the oils, be patient, it will be interesting))From my little experince with linseed oil I can tell you it changes the color of wood very subtly. After puting oil it is intense but it changes back to slightly highlighted original color after some time
Dzięki. Tak, foka wygląda przyzwoicie, jeśli zrobisz to dobrze.Witaj
Dziób wygląda bardzo ładnie wydruki są 3D są świetne, piękna ładna dokładna praca. Pozdrawiam Mirek
Then you will be interested in everything that I will soon publish. I made a sample of linseed oil last year, and gave it harsh conditions. On the balcony in the heat and on the finger of the sun. Of course, this will not happen in the room conditions, but I sped up what can happen in years. So, the sample darkened a lot. A little later I will show the difference.Good results with printed hinges they're also on my to do list.
How much time it took to darken? After couple of months I still can't see the difference or it's very slight
Hi SergeyHello everyone! Today, I’ll try to post the final part about the head rails... But for now, I wanted to share some news. Once again, I’ll be testing some samples, as I’ve ordered tung oil. I’m waiting for delivery, but unfortunately, I’ve run out of pearwood veneer, and I can’t remember where I got it. Now I’ll have to look for it elsewhere.
I think I’ll move away from teak oil—it has its pros, but also some cons. The way it interacts with bitumen has its nuances, which I’ll discuss later. Tung oil appeals to me because it’s matte and allows for gluing over it. In short, I’ll test it and then do a big comparison of three oils: linseed, teak, and tung. I’m also missing Danish oil, but who knows, maybe I’ll try that one too eventually. Still, I hope tung oil will be the one I settle on—as long as the tests meet my expectations.

Yes, such bases are definitely not needed, as well as a large number of supports. But I repeat, this post is about mistakes, and I wanted to show them all in one post. And about scanning the model... yes, sometimes from scratch is better, but only if you know how to do it. If you know how to slightly correct, add or adjust something, then the option of working with a scan should be quite working. But I have not done this yet. As soon as I do, I will tell you. And as for the finished successful results, they will be soon and they should surprise you.I'm still waiting for final part
As for now I can tell you, you don't need such big islands under models. It's only waste of resin. They're crucial only to very fragile and thin models like flowers or belaying pins etc.
Another thing I heard: it's better to build 3d model from scratch then to clean a model from errors such scan creates - can you confirm it or did you use scaned models as a final form?
Good morning. Awesome post. I’m still learning 3D printing and have done some successful prints for my Xebec and Bounty. I have kept the printing to metal parts only (although on my Bounty I did the deadeyes) as I feel it does detract from the Authenticity on wooden parts. Brilliant hinges BTW.

So, we’ve gradually arrived at the present… well, almost. To truly start, we need to take another step back into the past. The topic is quite extensive. I’m not sure how many posts it will take before I get to showcasing the actual construction, but a prologue is unavoidable. The introductory section will be titled:
"Trials and Errors" in
3D Modeling and 3D Printing.
Note! This post contains many photos with mistakes, unsuccessful experiments, and trials, and I repeat – MISTAKES. Please do not perceive these results as representative of 3D printing as a whole. I just want to show what to avoid, and later in the posts, I will present the successful results!
The model features a significant amount of carved decorative elements. While this particular ship doesn’t have an overwhelming amount, there are still notable pieces, such as the figurehead, the patterns surrounding it, the stern gallery, and numerous other carved details. These need to be created somehow. Ready-made options that fit my scale are either nonexistent, of poor quality, or prohibitively expensive. Hand-carving them or ordering CNC work wasn’t an option for me. So, I needed another solution.
That’s when I came up with a promising idea: **scanning figurines** (wherever I could find them) and then adjusting them in a 3D modeling program to fit my requirements.
Later, I had an even crazier idea: **scanning the entire model** and using that scan to create nearly everything—deck details, rigging, and more. However, I soon abandoned that notion, deciding instead to maximize the use of wooden components. Despite this, the idea of using 3D modeling for decorative elements remained viable.
I managed to acquire a figurehead and several other tin parts from colleagues who were building using partwork kits...

I was able to acquire several other decorative elements from DeAgostini assembly magazines. I scanned all of them using an intraoral scanner—being a dentist, this was no trouble for me.
This method allowed me to capture highly detailed digital replicas of the parts, which I could then modify in 3D modeling software to better suit my project. It turned out to be an efficient and precise solution for replicating intricate decorative elements.
View attachment 485224
The quality of the scans wasn’t perfect, but they provided a solid foundation for further modeling. Specifically, they served as a base for design corrections in **Blender**, where I could adjust the scale, enhance the level of detail, and fix any imperfections. This approach will come into play later when I focus on refining the primary decorative elements.
For now, I’ll list all the key trials and errors, along with the corresponding solutions, below. Let’s get started!
1. Scale Issues
Each model has its specific scale, but it’s crucial not to overlook the technical limitations of your 3D printer. While you can design details down to a micron, the printer might not be able to reproduce them accurately.
I encountered this issue while printing cannons. The rings and eyelets on the carriages were so thin that even if they printed successfully, they broke during post-processing.
Solution:
In subsequent designs, I accounted for this by increasing the thickness of rings and other fragile details. Additionally, some elements need to be intentionally exaggerated in size because they would otherwise be invisible on the model. Balancing realism with practicality is essential when working with such small-scale projects.

By the way, I didn’t initially plan to delve deeply into this topic, and since my wife was familiar with the 3D program Blender, she was the one who modeled the first cannons and carriages for me. However, I later realized that it was interesting, and I started studying everything in detail myself. In the photo below, you can see a model printed with small elements that broke. Next, I will show how I changed everything. In the meantime, on to the next point...

2. Positioning and supports.
When printing, it’s crucial how you position the part. Avoid placing it horizontally. This will result in numerous supports, the part may warp into an arch during curing, and most importantly, flat surfaces can detach and cause the print layers to delaminate. Regarding supports, don’t position them so that their flat areas rest against the part. In such cases, they’ll be difficult to remove without damaging the part.
Solution: Position parts either vertically or at a 45-degree angle (depending on the part itself; I’ll show examples later). Place supports manually so that only their tips touch the model, not their bodies.
Also, avoid creating a single continuous base for all elements, as it will deform and result in defects. Instead, divide all elements into groups or separate them so that the base is fragmented.

Incorrect positioning (the carriages placed horizontally, plus it will be difficult to align the surface of the gun barrel after the supports).

Correct positioning (the carriages at an angle, and the guns with the rounded part facing down, which will be easier to polish after removing the supports).

3. Painting and Preliminary Processing. Print Layers!
I combined these two points into one because the end result for us is a painted part. The most important aspect of its appearance after painting is the visualization of the print layers. I recommend using only photopolymer printing and only at 20 microns, no more. I tried 10 microns, but it increases the risk of defects, and at 30 microns, the print layers (steps) become clearly visible. As for painting, you should only choose deep matte aerosol acrylic paints. I tried others – neither enamel nor other options work. Enamel gives a plastic effect, while not matte paints give a toy-like effect. I chose matte camouflage aerosol paints based on acrylics for myself. The photo below shows the print layers and how the wrong paint looks.

I’ll repeat! These are unsuccessful attempts. And this paint is not suitable. The one that works for plastic will be shown in the next posts.
The material on 3D printing is still in progress, and I will continue to talk about mistakes and nuances in future posts. What I wanted to add is that over time, I got better at modeling, and here are a couple of samples.
Some of this I have already redone... and not just once, fortunately, I got a printer at home (I took it from work when we did an update there), so now I can print whatever I want and as much as I want.

I will go into more detail about all this later with specific examples, but for now, I just kept printing and painting...

In the upcoming posts, I will talk about and show the final models and how I process and paint the printed details. And of course, I will demonstrate how I adapt these details into the wooden hull so that they don't look toy-like, but rather as if they are made of wood, just painted.

I have always been open to new technologies. If a part is under paint, I see no reason to be principled about what is under this paint))Good morning. Awesome post. I’m still learning 3D printing and have done some successful prints for my Xebec and Bounty. I have kept the printing to metal parts only (although on my Bounty I did the deadeyes) as I feel it does detract from the Authenticity on wooden parts. Brilliant hinges BTW. Cheers Grant
This is just the beginning, when I show the feed, many will think about it. I have almost finished it, I think I will post it in a few days.Hey, whatever works! These are enviable!
True storyThese are enviable!
Oh, these are very good questions! I have briefly covered some of the information, but I understand that it would be better to go into more detail about your questions. I think I will create a post with answers and illustrations and I will tag you so that you do not miss it. Thank you for your interest!Very interesting work with the 3D parts.
Can you explain a little to those of us with no 3D printing experience, how you get the parts into the 3D software?
Which software do you use?
How do you ensure scale?
What machine do you use to print, what settings and what material?
I noticed that some of the heart blocks did not have channels to allow for the rigging thread, and I appreciate that you go to some lengths to highlight that your post was about your learning curve and mistakes made, but will successful dead eyes, blocks and hearts need drilling to make them useful?
Thank you Sergey for sharing your knowledge, it is very appreciated.
