Title: 3D Resin printing - on my new printer
Post by: Snowwolflair on April 03, 2019, 08:43:10 PM
I have had 3D printers for over fifteen years, where the earliest ones were like the first generation 360 by 240 digital cameras and today's state of the art printers are about the same as a 4MB pixel camera.  The point I am making is that what we had early on was crude and not worth of serious modelling and that what we can now buy is certainly capable of producing very usable models.  What the future brings inevitably will be better.

Not least is the quality of preparation software now available that makes the task of preparing and printing a model no harder that using Microsoft Paint.

For some years I have been watching the development of LCD-SLA printers where an LCD is driven like a computer screen placing a UV pattern on resin which hardens it.  Multiple layers forms a 3D solid.  The problem with the early versions of these printers is they had small build plates. 

My first printer of this type had a build plate of 60mm by 40mm and was designed to print wax resin masters fro jewellery.  It produced very fine detail but the biggest item it could print was a small wagon and that was a struggle.   I was therefor very pleased to find that the new generation of these printers can print an area equivalent to A5 sheet of paper 190mm by 120mm.   This is a game changer as this size of build plat allows a Mk3 coach to be printed flat and square to the plate.  So I took the plunge.  :)

A picture is better than a thousand words and these shots sum it up nicely.

I am currently running tests as I have leapt in at the deep end with the highest complexity print I have and, fortunately, it has come out 95% first time and I am learning how to get the last 5% which is all about generating the support structures.  My plan is to add more posts as I learn what tweaks work.

Not a bad looking print. Which brand of printer is it? 

I cant see in the picture but is the Z axis fitted with either a trapezoidal or ball screw?

It's a Phrosen Shuffle XL and it uses a ball screw for the Z axis.

They have a dealer in Hatton Garden London, which is part of the reason I bought it, for support, parts and resin.  Its unsurprisingly become very popular with jewellers.

This is a first print using default values and I'm already improving the print quality.

A few photos from my experiments.

The main issue of printing using an LCD-SLA printer is making sure overhanging parts don't sag when printing.  You avoid this with thin props that hold up the vulnerable points.  The downside is the props are part of the print and have to be cut off leaving point marks on the print and if they are wrongly place can touch over more than just the point contact.

Take a look at the two photos of the Zeppelin Air Car showing poor supports and much better supports.

If you have bad supports you get adhesion on the surface as can be seen on this print and how it looks when corrected.

Stating the obvious, supports on the inside are unimportant and easily removed.

The final results look excellent :thumbsup: :thumbsup:
Did you "draw" the last 3D designs yourself or is there an online repository where you can buy designs?  I have been looking and there are a few suitable files for scaling down to N gauge available on Thingiverse, but only of line-side equipment.
I recently bought an Anycubic Photon and intend having my first go at 3d printing this coming w/e: am anticipating a steep learning curve! ::)

The prints of the Zeppelin Rail car and the GWR Rail car are publicly listed and free to use non commercially.  The GWR file is well designed whilst the Zeppelin has known errors and I wanted to see how the software treated these errors.  In practice there are bumps but no loss of integrity which is good.

Here is the Zeppelin cleaned up and sat on a Tomix chassis as a test. Sanded and filled its going to be an eye catcher

That Steam Railmotor looks very good I have made one out of an Auto coach but that looks much better as an auto coach isnít really long enough .
I will put my order in for you to paint and line ,and finish with transfers ,next time I see you , I can use the little chassis I have allready it might not be 100% accurate but it will have to do ,no hurry as I know you are very busy with your other projects .

Ok, third learning cycle on the GWR Rail car and I'm happy with the result.  Each cycle has removed more supports, that are automatically generated by the software, from the outside of the model.  I have not lost any integrity of the shape and I suspect that I could remove even more supports and retain the shape.  The third print is certainly up to Shapeways FUD standards.

Only just seen this and all I can say is WOW!!  :o  If this is the sort of quality that modern 3D printers can produce, I may have a project that I was going to have a go at scratch-building, but this looks like a quicker prospect! Where are such models listed, so that I can find if they have an example of this -

This is a 1930's high speed diesel rail-car used in southern Poland, for first class passengers be=tween Krakow and the skiing resort of Zakopane. The first time I saw it I decided that I would love an N gauge model of this one day, and I even have an almost correct sized chassis waiting for it!

This is the quality the latest printers can print for this size of print.  I have had a smaller printer for seven years that can print 2" by 1" but impossible to print something this size.  Shapeways have been able to offer printing like this fro a few years but the machines are +£20,000 where as the modern machines for home use of this quality are now from £400 to £1,400.

This particular model was a download from Thingverse and I used it as a good known design to test my printer.

I do like your rail car, it would make an eye catching model.

A general thought.

If your CAD skills are not up to making a model there are designers for hire through Shapeways for quite reasonable sums to do CAD for you and they will also make sure their designs meet Shapeways design rules.  Most are students earning beer money.

I like his work.  CAD becomes second nature with practice.  I have used 2D CAD since the days of DOS, but have done little in 3D until I started to work with 3D printers.  My first 3D printer was 15 years ago and was a first generation RepRap and the CAD was block architecture.  Im now on my fourth  :) but this is the first viable one for N Gauge as it has a footprint of A5 so I can print full coaches flat and square (or angled if it improves the print).

With the evolution of engineering I have to use CAD, CAM and interact with G Codes.

But I've reached the conclusion that there is no one who knows every inch of CAD & CAM especially the top end programs as they have evolved over the years with each year having more software data added to them.

The complexity of CAD software can be immense especially surface modeling. High end software such as the likes of CATIA, Solidworks and PTC Creo are programs that require in house training before anyone can go out into the big world to work as a CAD engineer.

Of course there is always good old youtube videos for those who want to venture down the self taught route, but even so years of practical experience doesn't automatically make people qualified for which there are obvious reasons.

That's a lovely model! But I doubt that I could ever design something that good, as I have no experience with CAD or any other design software! (I can use these infernal machines for a fair bit, but CAD looks beyond me!)

True, but I think its too general a statement.  AA is a mathematical algorithm and is like putting a filter on your camera.  It delivers a different effect usually based on interference patterns.

With AA on it adds smoothing between layers by degrading them to give a better transition giving a smoother surface over larger areas, however, at the same time it also adds smoothing to detail which generally being small is distorted, and in some cases is removed.  (i.e. a planked wood surface in N can loose the inter plank grooving or the safety valve cover on a GWR loco looses the sharpness of its profile).

I find the best way to proceed is to try both on and off and pick which I prefer as there is no always correct way.

By example if I was making a steam locomotive that would use separately printed fittings (like the one i'm working on) I would switch on AA for the shape of the body where there is little fine detail, and switch it off to print the detailed parts.

I use ChiTuBox to prepare files as it holds the printer and resin profiles.  I primarily accepts stl files, however its a free download if you want to try compatibility.

Now that we can get Professional quality bodies at the ( literal) press of a button, what are the possibilities of chassis production using (?sintering) - or are metal loaded plastics a possibility?

Itís  the prospect of applying an 18c technology ( a file) to a 19C chassis to support a 21C body that depresses me!

However I stand in awe at your ability to knock up new parts in ď minutesĒ

I did some tests on a print resin yesterday called Rock Black and when hard it has the characteristics of chassis plastic.  I don't see any reason that with some careful design chassis could not be created, possibly using the 2mm society brass axle bushes as inserts to stop wear.

The other thing to remember is that it is possible to print in casting wax.  This can then be commercially lost wax cast in brass or other metal to give weight.  I might need to do this with the SR Lord Nelson tender body or chassis.

Very interesting indeed! I am going to be shortly taking the plunge by getting an AnyCubic Photon Resin printer. So I will follow this thread! Shapeways has just become so stupid in their pricing/shipping, that it is time to go the DIY route. Hopefully it won't be a terribly painful exercise. At first I will look to print others STL files - you can buy loads of them or get them free at various places - so that I can learn what is what. Next step will be trying to design things...which to be honest, it the more daunting task! Still, I use to think I couldn't sculpt miniatures but I learned to do that at my old age....so might as well give it a try.

Not seeking to hijack this thread, but any tips/pointers/etc are welcome! :)

My advice is DO NOT buy the Model S its construction is plastic unlike the original and there is a known issue with the mainboard on it, the Phrozen snowwolf has is also good but more expensive as it has a bigger bed

The Phrozen printers are state of the art with parallel light sources as opposed to point source that gives a fish eye distortion effect with most others.  The distortion is not noticeable for "art" and structures but is you are printing an engineered structure you begin to notice it.  I also have no doubt the next generation will improve yet again.

In digital camera terms we are now at 2MP cameras.

Yes, I am on the Anycubic Photon FB page and gathered that the new 'S' model isn't all that great...and doesn't have all the user support of that the original one has. So I will go with the original one and make some adjustments based on other user's experiences. Should be fun...I hope!

Print volume depends entirely on what you want to print. General reviews seem a bit unhelpful in that respect. Iíd sooner have user reviews from people using them for railway modelling, like Snowwolflair and only_me.

There are a couple of threads on RMWeb with people using these, the results definitely look good. Iím sorely tempted.

As to the poor photon reviews, yes originally the ui wasnt very good but theres an hd one out now as well as anti aliasing fw and some cool features such as ethernet

The Photon is pretty unbeatable on price/performance and its low price means one can contemplate replacing it in a couple of years once tech advances have rendered it obsolete. The tiny touch screen is only a minor irritation and the "small print volume" is not really an issue for N Gauge prints as it equates to 17 x 10 x 23m in 1:148 scale.

Something I hadn't anticipated was how useful a 3D printer is for knocking out minor parts, such as a replacement 7mm buffer beam and buffers, a shortened Union Mills drawbar, and jigs for bending handrail wire.

Hopefully I will have enough pennies saved to get my Photon at the start of next month. Yes, I have read loads and loads of reviews of a variety of machines...most aren't all that helpful (a lot seem liked paid for reviews) and I settled on the Photon for the very reason that it has a really good community support base (loads of help), prints really nice (once you get the hang of it from what I read), and isn't going to bankrupt me! So let's try it...and who knows, I might be a 'Creative Sensation!'  Now if I can only get the guy that did that really nice looking 'GWR Saint' class loco on Shapeways to sell me the STL files I can have a go at making one of those!

After seeing some of the neat work that Only Me has produced, I have to admit I was tempted at one point in buying one of these printers.

Apart from the modeling and fun aspect of 3D printing I would like a printer for rapid tooling, sadly the Photon would not be up to producing the accuracy and quality required for that type of work, come to think of it nor any sold on the market within a sensible price bracket.

However on a more positive note its really refreshing to see modelers buying these cheap machines and pushing the boundaries, some of the results achieved through will power, time and experimenting have been amazing.

As far as I'm concerned those of you dedicating so much of your time to create models that are not commercially manufactured, are all pioneers and an asset to the hobby and deserve a big pat on the back.  :thumbsup:

3D printing is advancing in dog years and affordable printers are already close to matching the quality of injection moulding. Now is a good time to get on board.

Thanks but I have already been involved with trying 3D printing for my tooling and its not quite there yet for the type of work I do, especially when it is compared to the quality of EDM.

However hopefully in the not so distant future things will improve on that front when I eventually retire and have more time for my modeling.

I would say 2-4 years and personal 3D printing will be pretty darn good. I am amazed at what some people can get out of a resin printer. The FDM ones are just are fun it would seem, as getting them to do detail work without step lines is pretty difficult, if not impossible. The tech behind all this is fun stuff!

Going back to the GWR Saint loco, I would really like to print one of these.

I suspect that for a model of the detail of ATSO, myself or others are producing the STL files wonít be freely available.  However there are good STL files available free on Thingverse and other sites a couple of which are very good scale N items.

The best way to start is with a CAD program and ďplayĒ as you can always get Shapeways to print before laying out money on a printer.

Don't get me wrong, I was expecting anything for FREE...is there such a thing these days? LOL Given the pricing at Shapeways has gotten beyond stupid, I have noticed makers offering the STLs, or in some cases, home printed versions of their own work, for sale. Hence, I was wondering if this is possible, as I have decided to just avoid Shapeways.

As for Thingiverse, yes, a lot of good stuff there but I haven't had much luck looking for N-Gauge trains. I have however found loads of stuff for my son's Star Wars! ;)

PS This website offers STLs for sale....https://pinshape.com/

I definitely believe that printing on demand by the designers with their own printers is here.  I already offer my Shapeways listed items in FUD and in resin direct from myself.  It Is so much cheaper.

Pricing will become important as makers need to cover resin and other consumables as well as a mark up to pay for the cost of the printers.  Most modern printers or their CAD will calculate the cost of resin used per model and at the small end of the range the item price can be as low as 10% of the Shapeways FUD price.

@Doc Pye (https://www.ngaugeforum.co.uk/SMFN/index.php?action=profile;u=7313) So did you save enought to buy one?

Aditional question to
@Snowwolflair (https://www.ngaugeforum.co.uk/SMFN/index.php?action=profile;u=3761) @Only Me (https://www.ngaugeforum.co.uk/SMFN/index.php?action=profile;u=1328)

Have you tried the Plant based resins?

I bought a Photon last month, very impressed so far, keep meaning to start a thread with my amateurish beginnings. Also thinking of trying the plant based resins as mrs njee20 isnít wild keen on the smell of the normal stuff.

Double the price though...  :doh:

I would be interested in hearing about anyone's experience with the plant based resins, particularly their long term stability.  thanks

Try the white and grey anycubic resins they smell a lot less... Also you can attach a bathroom extractor to the rear plate on the photon to extract the fumes outside... theres an item on thingiverse that you can print on an FDM which is a replacement for the bottom back rear panel and it has an extractor hose part

Yeah I bought the grey on your recommendation, and that is noticeably less odourous thanks, but apparently still too much Į\_(ツ)_/Į

I don't find it offensive I must say (particularly they grey, the green was less pleasant).
