What Do You Actually Need to Start Resin 3D Printing?
A resin printer is only one part of the setup. Before you buy, you need a workable plan for resin, washing, curing, safe handling, cleanup, and where the entire process will happen.
The practical starter checklist
| Item | Priority | Why it matters |
|---|---|---|
| Resin 3D printer | Required | The machine itself. Choose size, resolution, workflow features, and ecosystem based on what you plan to print. |
| Compatible resin | Required | Most common LCD/MSLA hobby printers use 405 nm UV-curable resin; verify exact compatibility before buying. |
| Slicing software | Required | Prepares models, supports, orientation, and print parameters before the file goes to the printer. |
| Nitrile gloves | Required for uncured-resin handling | Helps reduce direct skin contact with uncured resin and cleaning chemicals. |
| Eye protection | Strongly recommended | Useful protection against splashes during resin handling and cleanup. |
| Washing method | Required | Fresh prints retain uncured resin and need to be cleaned before curing. |
| UV-curing method | Required | Post-curing completes the normal resin-print workflow. |
| Ventilation / exposure control | Important | Resin printing and post-processing can release chemicals and particles; source control and ventilation should be considered before PPE alone. |
| Silicone mat / containment surface | Strongly recommended | Makes drips and cleanup easier to manage. |
| Funnels / filters | Strongly recommended | Helps return usable resin while reducing debris in the vat. |
| Cleaning supplies | Required | Needed for the printer area, tools, containers, and post-processing workflow. |
| Storage | Recommended | Keeps resin, solvents, contaminated tools, and cured models organized and separated. |
| Airbrush / finishing gear | Optional | Useful for finishing models, but not needed to start printing. |
1. Choose the printer around what you want to make
Do not begin with the question, “Which printer has the highest resolution?” Start with the job.
Small miniatures, larger display pieces, functional prototypes, jewelry-style detail, and occasional hobby prints all create different priorities. Build volume, workflow, replacement parts, resin availability, slicer support, and post-processing capacity matter just as much as headline resolution.
If you are considering ELEGOO's Saturn line specifically, our Saturn 4 Ultra 16K beginner setup guide shows what the printer includes and what you still need around it.
2. Buy resin for your first projects—not for a future collection
ELEGOO's beginner guidance notes that its resin printers use 405 nm UV light. That gives you a practical compatibility check for common LCD/MSLA resin printers: confirm the resin is intended for the printer's wavelength and process before buying.
Standard resin, ABS-like resin, water-washable resin, flexible formulations, and specialty resins are not interchangeable in purpose. Start with one or two bottles that fit what you actually plan to print.
3. Slicing software is part of the equipment list
A resin printer does not simply take any 3D file and print it correctly. You normally need slicing software to orient the model, generate supports where necessary, choose layer and exposure settings, and export the print file for the machine.
This does not necessarily mean buying expensive software. Many resin printers work with capable free or bundled slicers. The important point is to confirm software compatibility before buying the machine.
4. Plan safe handling before opening the resin bottle
ELEGOO's current product safety information warns that uncured photopolymer resin can cause skin irritation, allergic skin reactions, and serious eye irritation. It instructs users to wear protective gloves and eye/face protection.
NIOSH also notes that vat-photopolymerization printing can expose users during resin dispensing, printing, resin recovery, washing, curing, sanding, cleaning, and maintenance.
5. Decide how you will wash prints
Resin prints normally leave the build plate with uncured resin on their surface. That residue has to be removed before final curing.
ELEGOO's beginner instructions describe washing with an appropriate cleaning method and also present the Mercury Plus 2.0 as a dedicated wash-and-cure option. A dedicated station is convenient, but it is not the only possible washing method.
The correct cleaning liquid depends on the resin manufacturer's instructions. Standard resin often uses IPA or another approved resin-cleaning solution. Water-washable resin changes the cleaning process, but contaminated wash water should still be handled responsibly rather than treated like ordinary household water.
6. You need a curing method too
Washing and curing are separate jobs. After washing, the model should be allowed to dry completely before UV curing. ELEGOO's beginner guidance specifically warns that curing a model before it is fully dry can leave white residue or impurities on the surface.
A dedicated wash-and-cure station makes this convenient, but the real requirement is having an appropriate UV-curing method for the resin and models you use.
7. Your workspace matters more than the printer footprint
Do not ask only, “Will the printer fit on this desk?” Ask whether the entire workflow fits.
You need room for the printer, uncured prints, gloves, resin, washing, curing, cleanup materials, tools, storage, and temporary waste. A small silicone mat or containment surface can make the resin-handling zone much easier to manage.
Keep uncured-material work together
Printer, resin bottles, uncured prints, gloves, washing containers, filters, and tools used around uncured resin.
Separate finished work
Fully cured prints, computers, painting equipment, packaging, and ordinary household items.
8. Think about ventilation and exposure control before choosing the room
NIOSH's guidance for desktop vat photopolymerization recommends lowering exposures through ventilation and effective particulate/gas filtration where appropriate. It also notes that washing solvents such as IPA can create additional exposure concerns.
This is why an occupied bedroom, office, or small enclosed room should not automatically be assumed to be suitable just because the printer physically fits there.
We will cover this in more detail in our upcoming Best Resin Printing Setup for a Small Room guide.
9. Cleanup supplies are not optional
A useful starter cleanup kit can include disposable towels, resin filters, designated containers, cleaning solution appropriate for the resin you use, and tools that stay within the resin-printing workspace.
NIOSH recommends maintaining a clean work area and promptly cleaning resin drips or spills. ELEGOO also advises working in a well-ventilated area and using nitrile gloves and safety glasses during resin-cleaning operations.
10. What you probably do not need on day one
You can spend a surprising amount of money on resin printing before making a single model.
- A large airbrush setup
- Ten colors of resin
- A large inventory of spare LCD screens and major parts
- Expensive photography equipment
- Large premium tool kits
- Elaborate storage furniture
- Every printer upgrade sold for your machine
Start with what completes the printing, washing, curing, cleanup, and storage workflow. Then let your actual experience tell you what deserves your money next.
Three sensible ways to start
Start printing responsibly
Printer, suitable resin, slicing software, gloves, eye protection, manual washing method, UV curing, cleanup supplies, and a protected work surface.
Add dedicated post-processing
Add a wash-and-cure station and better organization if you expect to print regularly.
Improve after experience
Add finishing tools, an airbrush, specialty resins, replacement consumables, and more storage based on the projects you actually enjoy.
What I would buy first
Printer → one appropriate resin → slicing software → gloves and eye protection → washing method → curing method → suitable workspace/ventilation plan → protected work surface → filters and cleanup supplies → storage.
That order solves the actual workflow before optional hobby purchases begin consuming the budget.
If you are buying the Saturn 4 Ultra 16K
We already built a separate guide around a real Saturn 4 Ultra 16K setup paired with the Mercury Plus V2.0. That guide focuses specifically on what comes with the printer and what you still need around it.
Bottom line
You do not need a giant shopping list to start resin 3D printing.
You need a complete workflow.
Choose a printer that fits your projects. Buy compatible resin. Have slicing software ready. Plan safe handling, washing, curing, cleanup, ventilation, and storage before opening the bottle.
Then print something.
