My first post was back in February - before I had even purchased a 3d printer, and it is now November and I am writing the introduction... This blog is all about my experiences for 3d printing. It is a way for me to share what I learn along the way, and to show off what I have created. Most pages are tagged Model and are about a specific model, and the prototype it is based on. Generally I try to visit the prototype, and include a couple of photos of that for comparison. I also try to learn the history of the building, which is not always easy, and record that on the page too. A lot are buildings in and around Preston, as that is where I live. Models are further divided into Building , Railway (i.e., railway-related buildings), Feature (bridges, tunnel portals, etc.), Rolling Stock , Vehicle and Clutter (smaller items) In addition, there are pages tagged How to and Prototype . If you want to know how to use Blender to make 3d models, there is an article I wrote on another s...
They are hazards associated with resin 3d printing, and you should be aware of them and act appropriately. What do I know about it? I have worked in the chemical industry for several decades, part of my job is writing safety data sheets and I currently serve on a committee reviewed safety across an entire chemical plant. That said, I am not an expert on resin, so this is only a guide. You are the one who is ultimately responsible for your safety! iso-Propyl Alcohol (IPA) IPA is harmful and flammable. Keep it away from naked flames and electrical sparks. That said, with a flash point of 12°C, it is safer than acetone (-18°C) or petrol (-43°C). Do not drink it. Yes, it has alcohol in the name, but it would still be bad for you. Try to keep it off your skin, but it is not that big a deal. IPA was the main ingredient in the hand wash we were all deliberately putting on our hands during "lockdown", so it is really not that hazardous. If you have a reaction to IPA, it is more like...
I am doing a demo at the local N Gauge Society members day on Sunday, and will be assembling my viaduct to display it. To get it ready, I have been busy painting the last two days, so more photos. I painted iron arch bridge with bright colours, and it turned out well, I think, though my painting skills are not great. The plate girder bridge I did in plain grey. Similarly the lattice bridge. I am not so happy with his one; the proportions seem out somehow. An extended brick arch. And some filled in arches, with businesses. Again, very pleased with how these turned out.
