Looking at possibly doing an freight car an something that’s great quality an the material I’m looking to use is plastic

Take a look at the Prusa brand. If looking for really fine detail, then most likely you will need a resin printer.

If you're "Looking at possibly doing an freight car an something that’s great quality", then you'll want a resin (SLA) printer.
What's your budget? As with all things, you get what you pay for.
While the cheapest resin printers have impressive resolution, they can suffer from Z-axis wobble. Paying a bit more can improve that markedly. Also, the cheapest models have limited print volume -- you can maximise the size of parts you can print by printing parts on an angle (think Pythagoras). This can also actually improve the quality of the print by allowing for better support and making any Z-axis deformaties less obvious.
The cheapest resin printers can be had for well under $300 dollars, but eg the Epax X1 has virtually no Z-axis wobble and costs about $450. If you need more print volume, be prepared to pay a lot more.
I've learned a lot from the site all3dp.com They have a Buyer's Guide which they update regularly, and reviews of most of the affordable printers.

My budget for one is around 5k an I appreciate all the insight you guys are offering me, I’m new to all of this and it’s a side of the hobby I want to explore. I never knew anything about resin printers, are they better than the 3D ones?

My budget for one is around 5k an I appreciate all the insight you guys are offering me, I’m new to all of this and it’s a side of the hobby I want to explore. I never knew anything about resin printers, are they better than the 3D ones? As I understand it, there are two basic types of 3D printers: - Extrusion printers (also called Fused Deposition Modeling (FDM)). A spool of material passes through a heated nozzle which moves depositing a small amount of material which then cools and hardens. The object is built from the bottom-up.
- A resin printer on the other hand floats a thin layer of resin above a surface, often an LCD screen outputting UV light. The LCD screen will light up where the resin should solidify. After a short time, the solidified layer is lifted slightly out of the tank and a new layer is solidified underneath it. The object is thus built from the top-down. See a time-lapse here: Resin prints do require some post-print cleaning and processing.
For your budget, you should be looking at a resin printer such as the Formlabs Form 3. |
