Holiday 2025 3D Printer Guide:
The most common mistake new Makers make during the holidays is buying the wrong type of printer. You see a stunning, smooth D&D miniature online and buy the printer that made it, not realizing you just signed up for a chemical handling hobby.
In Part 2 of our Buyer's Guide, we are settling the debate: FDM (Filament) vs. SLA (Resin). Which one actually fits your lifestyle?
The Basics: How They Work
FDM (Filament)
Think: Hot Glue Gun
It melts a spool of plastic wire and draws the object layer by layer. It is mechanical, robust, and generally safe for a home office.
Best For: Functional parts, cosplay helmets, tools, toys, large objects.
SLA (Resin)
Think: Sci-Fi Lasers
It uses a UV screen to cure liquid toxic goo into solid plastic, layer by layer. It offers infinite detail but requires strict safety protocols.
Best For: D&D Miniatures, jewelry casting patterns, tiny anime figures.
The "Hidden Costs" of Resin
Resin printers (like the Elegoo Saturn or Anycubic Photon) are incredibly cheap in 2025. But the price tag on the machine is a lie. To run a resin printer, you need a full "Post-Processing" workflow.
Safety Warning:
Liquid resin is a skin irritant and toxic to aquatic life. You cannot pour the waste water down the sink. You must wear nitrile gloves, eye protection, and work in a well-ventilated area.
If you buy a resin printer, you must also buy:
- Isopropanol (IPA): Gallons of it, to wash the uncured slime off your prints.
- Nitrile Gloves: You will go through boxes of these.
- A Wash & Cure Station: A machine that swirls the print in alcohol and then blasts it with UV light to harden it.

Our 2025 Recommendations
If you choose Resin: Elegoo Saturn 4 Ultra
If you accept the mess because you need perfect Warhammer 40k armies, get the Saturn 4 Ultra. In 2025, it introduced "Tilting Vat" technology, which physically tilts the tank to peel the print, making it 40% faster and much more reliable than older machines.
If you choose Filament: Stick to the Bambu A1
As mentioned in Part 1, for 95% of people, a filament printer is the correct choice. The detail on modern FDM printers is good enough for almost everything except professional model painting.
The Verdict
Buy a Resin Printer if: You are an artist, a jeweler, or a wargamer who paints miniatures, and you have a dedicated garage or workshop with ventilation.
Buy a Filament Printer if: You want to print fun toys, fix things around the house, make cosplay armor, or if the printer will be in a living space with children or pets.
