FDM printers melt plastic filament layer by layer. They are cheaper to run, cleaner to use and better for large and functional parts. Resin printers cure liquid resin with light and produce far finer detail, ideal for miniatures, jewelry models and figurines. Resin also needs washing, UV curing, gloves and ventilation. Most beginners should start with FDM unless detailed miniatures are the main goal.
The two main home 3D printing technologies suit very different projects.
Side by side
| FDM (filament) | Resin (MSLA) | |
|---|---|---|
| How it works | Melts plastic filament through a nozzle | Cures liquid resin with UV light |
| Detail | Good; visible layer lines | Excellent; very fine detail |
| Build size | Larger | Usually smaller |
| Strength | Good, especially PETG and ABS | Brittle to tough, depending on resin |
| Post-processing | Remove supports | Wash in alcohol or water, UV cure |
| Mess and safety | Low | Gloves, ventilation, careful waste handling |
| Running cost | Lower | Higher |
Choose FDM if you want
- Functional parts, prototypes and household fixes
- Larger prints
- An easier, cleaner workflow
Choose resin if you want
- Tabletop miniatures, figurines and busts
- Jewelry models and dental-style detail
- The smoothest surface finish
What to look for in an FDM printer
- Auto bed leveling
- Direct drive extruder for flexible filaments
- Build volume that suits your projects
- Enclosure for ABS and ASA
- Speed, input shaping and reliable firmware
What to look for in a resin printer
- Screen resolution (pixel size in microns)
- Build volume
- A wash and cure station
- An air filter or a ventilated space
Getting started
Begin with test prints and the manufacturer’s slicer profiles. Expect a learning curve with supports and orientation on both types.
Common questions
Is resin printing dangerous?
Uncured resin can irritate skin and the fumes can be unpleasant, so wear nitrile gloves and eye protection, ventilate the room, and cure all waste before disposal.
Which 3D printer is best for miniatures?
Resin printers produce much finer detail and smoother surfaces for miniatures and figurines.
Which printer is best for functional parts?
FDM. Materials such as PETG, ABS, ASA and nylon make durable brackets, enclosures, tools and replacement parts.
