The printer is the headline purchase but not the only one. This is the complete list of what a new 3D printer owner actually needs in the first month, organized by what’s essential immediately versus what can wait. Buying everything on this list at once during Black Friday week, when filament and accessories are also frequently discounted, is more efficient than piecing it together over several confused weeks.
Essential for Day One</h2 - 2-3 spools of PLA filament. Start with at least one neutral color (black, white, or grey) for testing and one fun color for the first real project. eSUN PLA+ is a reliable, widely available starting filament.
- Isopropyl alcohol (90%+) and lint-free cloths. For cleaning the build plate before every print. Bed adhesion failures are the most common first-week problem and this solves most of them.
- A flush cutter or small scissors. For trimming filament and cutting away brims, skirts, and support material.
- A spatula or scraper tool. Usually included with the printer, but a backup is worth having for removing stubborn prints.
- Digital calipers. Under $15 for a basic set. Essential for verifying dimensions, especially for anything functional like deck boxes or replacement parts.
Useful Within the First Month</h2 - Filament dry box or airtight storage containers with desiccant. Especially important in humid climates. PLA degrades slower than other materials but still benefits from sealed storage.
- A second nozzle (hardened steel) if planning to print specialty filaments. Wood fill, glow, or any abrasive material will wear the stock brass nozzle quickly.
- A small selection of PETG. Once basic PLA printing feels comfortable, PETG opens up more durable, functional projects.
- A simple sanding kit (120-400 grit) and filler primer. For anyone interested in painting or finishing prints rather than leaving them raw.
- A dedicated shelf or cart for the printer. If it’s currently on a kitchen table or temporary surface, a permanent stable location improves print quality and reduces the chance of accidental bumps mid-print.
Can Wait Until There’s a Specific Need</h2 - An enclosure tent. Only needed once printing ABS, ASA, or other warp-prone materials on an open-frame printer.
- Specialty filaments (TPU, carbon fiber, Nylon). Each has its own learning curve; don’t buy these until standard PLA and PETG feel comfortable.
- A second printer. Tempting once the hobby takes hold, but unnecessary for the first several months.
- Resin printer add-on. A completely different process with its own learning curve and safety considerations. Worth considering only once FDM printing feels well understood.
