The only real limitation when using regular FDM 3D printers for building and designing scale models is surface finish, you can often clearly see the layer lines and removing them by using putty and sanding is often more work than its worth...... STEP IN RESIN PRINTING
3D printing has exploded in popularity over the past 5 years and it continues to grow.
This is the Anycubic Photon DLP 3D resin printer, I recently bought it through AliExpress however it can be found on just about any of the major platforms like Amazon and eBay. It's relatively cheap in comparison to similar printers and if you're making high detailed scale models then I definitely recommend this printer.
All of the models are printed in 1:87th scale.... (ho scale)
So far I've made a bunch of different models while I test and film the tutorial video I'm working on and so far I'm more than impressed.
There are some small limitations and imperfections that I'll talk more about when I write my comprehensive review all of which can be dealt with or minimized with careful planning and object design and none of which have deterred me from using this awesome little printer.
This printer will make many more appearances in future videos especially for making very small details to compliment other models.
Also after I finish filming the 3D printer video tutorial I'll be working on a resin mold making and casting tutorial on making and casting this shipping container (Also made using the resin 3D printer).
Be sure to stay tuned as the filming process has just been completed and I'll be posting the tutorial video in about 4 days time.
I'm very excited for the future of model building especially when products and tools like these 3D printer are being developed and improved upon ever few months.
