Re: 3 D Printing 16mm models

Thanks for the tip.

There were a couple of reversed faces in 2 separate components, and the spectacles needed to have their "faces intersected" Prints OK now.

Re: 3 D Printing 16mm models

The latest components printed and assembled: IMG_0791.jpg IMG_0793.jpg I have had issues printing the spectacle plate. Sketchup only identifies "nested object" issues in the inspector subroutine, so it should be OK. The slicing software loads it and it shows all the correct features. Howev...

Re: 3 D Printing 16mm models

Thanks for the information on the livery. That is really important to me. I like to make things as they were.

Yes it is coming along quickly - the cab is mostly printed.

Re: 3 D Printing 16mm models

I have just had one of this moments when you have to laugh out loud at something which has worked better than you thought possible! So I have to share it. A key visible feature of this locomotive are the louvred shutters which form the cab side windows. Any model of this loco would have to have them...

Re: 3 D Printing 16mm models

So another digression from 4415: I have already mentioned that I am making a live steam model of "Linda" - with a tender as running on the Festiniog railway. I have produced a set of inserts to go inside the tender to separate and hold the different parts in place. So firstly the lower tra...

Re: 3 D Printing 16mm models

The gearbox. It consists of three parts as shown in this view: IMG_0777.jpg They were printed with the side which is on the right of each component flat on th ebed. Printing small parts like this at 5 degrees higher than default makes the face nearest the bed solid and clean. It does make it harder ...

Re: 3 D Printing 16mm models

Now for something slightly different. I placed this thread under the general heading because I want to focus on how 3 D printing can affect all parts of garden railways, rather than on a particular model. As some of you will be aware I have been extending my railway during lockdown, and the extensio...

Re: 3 D Printing 16mm models

I thought you might like to see what the engine casing looks like when ti has some paint on it. So a thin coat of Valejo acrylic polyurethane airbrush primer, followed by a single coat of thinned Humbrol matt Eggshell blue which I found in the box of paints: IMG_0771.jpg And showing more of the fron...

Re: 3 D Printing 16mm models

The engine box lid and top has now printed. Here is the result straight out of the printer: IMG_0759.jpg This has worked as well as I had hoped it would. The surface is very smooth - and ready to just paint. However when I print things on their side like this (roofs are normally printed this way aro...

I have put together a guide to how I go about making the models that I print in Sketchup. It is intended to follow on throw the beginners guides in the reference section.

Re: 3 D Printing 16mm models

Andrew Than you for your encouragement! I will be interested to see how you get on reported on this Forum. The only comment I would make is that MDF seems a strange material to make models from ( know you can buy kets made from it). Acrylic I understand. The problem to me is that MDF is Hydroscopic....

Re: 3 D Printing 16mm models

Peter

You are of course entitled to your opinion.

However the whole point of this is that most of the time I am not doing ANY cleaning up of surfaces. The models I have shown have just been printed and painted.

Re: Using SketchUp to produce drawings for 3-D Printing

Hi

Interesting information.

Does this mean that Sketchup has a limited life expectancy-if it is unsupported that is?

The Fusion 360 thread was also interesting. I hadn't realised that Sketchup worked in triangles - but it does explain why circles come out as 28 sided objects by default.

Re: 3 D Printing 16mm models

Tried printing with a Brim and the filament didn't stick to the bed. So I will continue to print with a raft for now. I have good quality prints for both sides of the engine cover: IMG_0721.jpg and a finished print of the engine cover lid/front. While most of that is good I am not satisfied with the...

Re: 3 D Printing 16mm models

Interesting. Unfortunately 100 C is as high as the bed temperature goes. I will try a brim instead. I tried it without a brim or a raft and nothing stuck - black or white! I don't have problems separating the raft - rather the opposite at the moment! I suspect that my printer is intended to use a ra...

Re: 3 D Printing 16mm models

The last photo on the last but one post showed the spectacle plate printing. Let me share the results with you: Firstly the print was mostly successful. The top surface is really good: IMG_0708.jpg The only minor issue is that 3 rivets are not there. You might just be able to see them on the right u...

Re: 3 D Printing 16mm models

I am now thinking about printing the bodywork, and the front and top of the engine casing in particular. I find that I get the best results printing things flat on the bed with the "good" face uppermost. The rivets seem to print out cleanly. This part is a bit more difficult let me show wh...
