What are the key criteria for choosing a resin printer?
The five essential criteria are: build volume size, XY resolution (18–50 μm), print speed (90–150 mm/h), total equipment cost, and compatible resin type (water-washable vs. IPA).
After years of watching people buy the wrong printers, I'll be straight with you: 80% of problems come from not thinking through these factors before reaching for your wallet. Resolution is the first thing everyone looks at, but trust me — a small build volume will frustrate you far more than a few extra microns ever will.
Resin washing is a critical factor that almost nobody considers upfront. If you live in a small apartment without dedicated ventilation, isopropyl alcohol (IPA) can be a real problem. Water-washable resins solve this, but they cost more and don't work equally well in every printer.
Print speed matters if you're running long batches. The Elegoo Mars 5 Ultra for miniatures reaches 150 mm/h according to official specs, while more basic models hover around 40–80 mm/h. Keep in mind — those top speeds require a specific high-speed resin. With standard resin, you're looking at around 90 mm/h.
What size parts do you need to print?
For 28–32mm miniatures and small parts, a printer with a 130x70x150mm build volume is plenty. For busts, helmets, or mid-sized prototypes, you need at least 200x120x200mm.
The most common mistake I see is buying a compact printer thinking "I'll upgrade once I get the hang of it." Spoiler: you end up buying another one within six months. Standard tabletop miniatures are 28–32mm tall, and with a Mars 5 Ultra's 153.36 x 77.76 x 165mm build volume, you can fit a full squad in a single print.
If your goal is cosplay helmets or functional prototypes, go straight to the Elegoo Saturn 4 Ultra mid-size format. With double the print area of a Mars, you avoid the headache of splitting models and gluing them back together.
A tip most people overlook: measure the largest object you want to print and add 20% to each dimension. That gives you the real minimum build volume you need, accounting for supports and clearance.
What's your budget for a resin printer?
Your real budget needs to cover: printer (€200–600), wash and cure station (€100–200), starter resin (€30–50), safety gear and consumables (€50–80). Realistic minimum total: €400–500.
Let's be honest: the printer price is just the starting point. I've seen too many people buy a cheap Photon D2 and then realize they need another €200 in accessories just to work safely. The Mars 5 Ultra at €279 looks expensive next to €150 models, but it includes features you'd pay extra for elsewhere.
A wash and cure station is practically essential. Sure, you can do it manually with containers and a UV lamp, but after the third time spilling IPA in your bathroom, you'll be glad you spent that extra €150. The Elegoo Mercury XS Bundle or similar stations save you hours of hassle.
- Entry-level printers (€150–250): Anycubic Photon D2, Mars 3
- Mid-range (€250–400): Mars 5 Ultra, Photon Mono M7
- Large format (€500–800): Saturn 4 Ultra 12K, recent 14K models
Do you prioritize print speed or maximum detail?
For miniatures and jewelry, prioritize XY resolution under 25 μm. For prototyping and production, print speeds of 120+ mm/h combined with strong light uniformity (90%+) will deliver more value.
Resolution is partly a marketing trap. Anycubic boasts 16.8 μm in X on the Photon Mono M7, but in practice, the difference between 18 μm and 25 μm is unnoticeable on 90% of prints. What you will notice is waiting 8 hours instead of 4 for the same part.
Light uniformity matters more than raw resolution. The Mars 5 Ultra advertises 92% uniformity with its COB system, while traditional LCDs typically hover around 80–85%. This means fewer failed prints at the build plate corners and more consistent layers.
For production runs or iterative prototyping, every minute counts. An Elegoo Saturn 4 Ultra 16K might seem like overkill with its 19x24 μm resolution, but if you bill per finished part, the speed pays for itself fast.
Do you need water-washable resin or standard resin with IPA?
Water-washable resin is ideal for enclosed spaces and beginners since it avoids harsh chemicals, but it costs 40–60% more. Standard resin with IPA delivers better mechanical properties and a wider range of options.
I work in a well-ventilated workshop, so IPA is no issue for me. But if you're printing at home — especially with kids or pets around — water-washable resin is practically a must. IPA is flammable, the fumes are unpleasant, and you'll need to handle chemical waste disposal.
The compatible resins to get you started cover both types. Quality has improved dramatically — early water-washable resins were notoriously brittle, but current formulations hold up well under normal use. That said, for mechanical parts or anything requiring flexibility, I still prefer standard ABS-like resin.
One important note: not all printers handle water-washable resins the same way. Some require longer exposure times. The resin settings calculator helps you dial in the right parameters for your specific printer and resin combination.
Anycubic vs Elegoo: which resin printer brand is better?
Elegoo leads on value and a complete ecosystem (printer + wash station + their own resins). Anycubic pushes harder on technical innovation (DLP, massive build volumes) but with inconsistent customer support.
After years in this hobby, my take is straightforward: Elegoo is the safe bet. Their ecosystem is well-rounded — printer, Mercury Plus for washing, optimized resins, and support that actually responds. Anycubic innovates more (they were early movers on affordable DLP with the Photon D2), but their after-sales support is hit or miss.
On paper, the specs are very close. The Photon Mono M7 boasts a minimum 90% light uniformity and 16.8 μm X resolution. The Mars 5 Ultra counters with 92% uniformity and 18 μm. In real-world use, both deliver outstanding print quality.
The real differences come down to the details: - Elegoo has better quality control (fewer defective units out of the box) - Anycubic is often 10–15% cheaper during sales - Elegoo's software (customized ChituBox) is more stable - Anycubic offers a wider range of form factors (from compact minis to XXL build volumes)
When should you NOT buy a resin printer?
Skip resin printing if you don't have a ventilated workspace, are sensitive to chemicals, need large parts (over 30cm), require heat-resistant engineering materials, or can't commit time to post-processing.
Resin printing is not plug-and-play like FDM. Every print needs washing, curing, and support removal. If you want to print and use parts straight away, FDM is the better choice. Resin excels at detail, not convenience.
Space is critical. You need at least 2m² of well-ventilated workspace to print safely. I've seen people printing in closed bedrooms — bad idea. Resin fumes, even from "eco" resins, can cause sensitization over time. An exhaust fan or open window isn't optional.
For mechanical parts that need to be durable or withstand temperatures above 60°C, FDM with ABS or PETG still wins. Standard resin warps above 60°C, and heat-resistant resins cost three times as much. If you're printing outdoor enclosures or engine components, go straight to FDM.

Frequently asked questions about choosing a resin 3D printer
Is buying a used resin 3D printer worth it?
It depends on the model and its history. LCD screens have a limited lifespan — monochrome screens are rated around 2,000 hours per spec sheets. If you're buying used, ask about hours of use and request a test print. DLP models like the Photon D2, with its 20,000-hour projector lifespan, age much better. Personally, I prefer buying new with a warranty for the peace of mind.
What accessories do you actually need when starting out?
Beyond the printer itself: nitrile gloves (never latex), UV safety glasses, wash containers, paper towels, plastic scrapers, resin strainers, and a ventilated workspace. A wash-and-cure station saves time, but you can get started with manual methods. An air purifier with an activated carbon filter is highly recommended if you're printing indoors.
How far does a liter of resin go?
With a typical density of 1.1 g/ml, output varies depending on what you're printing. For hollow 32mm miniatures, you can get around 100–150 figures per liter. Busts or solid pieces use considerably more. Always hollow out large models to save resin and reduce cure times.
Are resin printers noisy?
Much quieter than FDM. The only real noise is the Z-axis motor moving up and down, similar to a paper printer. The Photon D2 is rated at 35 dB — practically silent. Any fan noise (on models that have one) can be more noticeable. In general, you can print overnight without disturbing anyone.
Do I need a powerful computer to prepare print files?
For simple models, any PC from the last 5 years will do. For complex files with millions of polygons or when auto-generating supports, you'll appreciate having 8GB+ of RAM and a decent processor. Slicing itself is fast — the heavy lifting is manipulating large STL files.
Can You Switch Between Different Resin Types Without Issues?
Yes, but make sure to thoroughly clean the vat between changes. Mixing standard resin with water-washable resin can cause curing problems. When switching colors, residue can tint your next prints. Many users keep multiple FEP vats on hand for quick swaps. An extra vat costs around €20–30 and is well worth it if you change resins frequently.
Happy printing! 😎
