3D PRINT
YOUR FIRST
GREAT THING
Everything a beginner and hobbyist needs to know about FDM and resin printing — from choosing your first machine to getting your first clean, beautiful print without the headaches.
FDM vs Resin
The single most important decision you'll make as a beginner is choosing your printing technology — and it matters more than which brand you buy or how much you spend. These two technologies solve fundamentally different problems.
Fused Deposition Modeling
Melts and extrudes plastic filament layer by layer — like a very precise hot glue gun building an object from the bottom up.
Photopolymer Resin
Uses a UV LCD screen to cure an entire layer of liquid resin at once — yielding extraordinarily fine surface detail.
If you have no 3D printing experience at all, start with FDM. It's safer, cheaper, and you'll actually use what you print. Once you know you love the hobby, add resin for detail work.
In 2026, the question isn't really which technology is "better" — it's which one is right for your specific goals. Most veteran hobbyists eventually use both: FDM to build the world (terrain, structures, functional parts), resin to populate it with legends (detailed miniatures, jewelry, figurines).
FDM: Your First Setup
FDM is where almost every serious hobbyist begins. The modern FDM printer landscape in 2026 has matured dramatically — machines like the Bambu A1 Mini and the Bambu P1S have raised the floor dramatically on what a "beginner" experience looks like. You can unbox, calibrate, and successfully print within an hour.
Step-by-step: Getting Your First Print
Level Your Bed (or Use Auto-Leveling)
The first layer is everything. If your nozzle is too far from the bed, filament won't stick. Too close and you'll scrape and clog. Modern printers with auto-leveling (ABL) handle this automatically — run the mesh leveling routine and trust it.
Set Correct Temperatures for Your Filament
PLA typically prints at 195–215°C nozzle, 50–60°C bed. PETG runs hotter at 230–250°C nozzle. Never assume — check your filament's label and slicer profiles.
Slice Your Model with Sensible Defaults
Open your STL file in Bambu Studio, PrusaSlicer, or Orca Slicer. Use the built-in quality presets. Don't tweak everything at once — start with 0.2mm layer height and 15% gyroid infill and only change what breaks.
Print a Calibration Cube First
Before printing your dream model, print a 20mm calibration cube. Check that all sides measure exactly 20mm with calipers. Adjust flow rate or steps-per-mm if needed. This 10-minute print saves hours of debugging later.
Remove Prints Carefully and Post-Process
Wait for the bed to cool before removing prints — most flex-plate beds let you simply bend and pop the print off. Sand with 120→220→400 grit for smooth surfaces. Prime before painting.
Even "safe" PLA produces ultrafine particles when printing. Keep a window cracked or run a HEPA/carbon air purifier in your workspace. ABS and ASA require an enclosure and dedicated ventilation — these are not beginner materials.

Resin: The Detail Sculptor's Path
In 2026, resin printing has hit an inflection point. Machines with 14K and 16K monochrome screens are now available for under $400 — delivering surface detail that rivals professional production equipment from just a few years ago. If tabletop miniatures, jewelry masters, or hyper-detailed figurines are your goal, no other technology comes close.
The Resin Workflow: What Beginners Don't Expect
Unlike FDM, resin printing has a mandatory post-processing workflow. Many beginners are surprised by this — your print isn't done when it comes off the build plate. You must wash it and UV-cure it before it reaches its final mechanical properties. Without post-processing, prints remain fragile, sticky, and potentially skin-irritating.
Prepare Your Safety Station First
Before touching any resin: set up nitrile gloves (not latex), a respirator or N95 mask, and ensure ventilation is running. Uncured resin is a skin sensitizer and produces VOC fumes. This step is non-negotiable.
Slice With Supports in Lychee or ChituBox
Proper support placement is the single biggest factor in resin print success. Use auto-support generation as a starting point, then manually add supports to any flat overhanging surface. Lychee Slicer's auto-support is the current community favorite.
Print — Then Don't Touch It Bare-Handed
When the print finishes, gloves on before touching. Use tweezers or the included scraper to carefully remove the print from the build plate. Go slow — freshly printed resin is still soft and can flex or break.
Wash in IPA or Water-Washable Solution
Submerge the print in 90%+ isopropyl alcohol (or water if using water-washable resin) and agitate for 2–3 minutes. A dedicated wash station like the Elegoo Mercury Plus makes this fast and clean. Two-bath washing (dirty first, clean second) gives better results.
UV-Cure for Final Hardness
Place the washed print in a UV curing station (or direct sunlight) for 2–5 minutes per side. The print hardens to its final strength and loses its tackiness. Remove supports after curing — they're more brittle and snap off cleanly.
Never pour liquid resin or IPA-resin waste down the drain. Let contaminated IPA sit in direct sunlight until the resin particles cure and settle. Filter the solid waste, let it fully cure, then dispose of it in regular trash. Pets and children should never be in the resin workspace.

Materials Explained
Every failed print or frustrating result eventually traces back to a materials decision. Here's what actually matters for each technology — without the marketing spin.
FDM Filaments
| Material | Difficulty | Best Use | Key Gotcha |
|---|---|---|---|
| PLA | Easy | Anything and everything as a beginner | Brittle in sunlight; not food-safe |
| PETG | Easy–Med | Functional parts, outdoor items | Strings badly if retraction isn't dialed in |
| ABS | Hard | High-temp parts, automotive, tooling | Warps constantly — needs enclosure + fume control |
| ASA | Medium | Outdoor UV-resistant prints | Same enclosure requirements as ABS |
| TPU | Medium | Flexible parts, phone cases, gaskets | Requires slow speeds and direct-drive extruder |
Resin Types
| Type | Price/L | Best For | Post-Processing |
|---|---|---|---|
| Standard ABS-Like | $20–35 | Miniatures, figurines, display pieces | IPA wash + UV cure |
| Water-Washable | $25–40 | Beginners wanting easier cleanup | Water wash + UV cure |
| Tough / High Strength | $35–60 | Functional parts, engineering prototypes | IPA wash + extended UV cure |
| Flexible | $30–55 | Gaskets, grips, wearable parts | IPA wash + UV cure |
For resin printers, stick to open-platform machines (Elegoo, Anycubic, Phrozen) that accept any 405nm resin. Closed-ecosystem printers like Formlabs charge $149–299/liter vs. $20–40 for generic open resins — the long-term cost difference is enormous for hobbyists.
Slicer Software in 2026
A slicer converts your 3D model (usually an STL or 3MF file) into the machine instructions your printer follows. Choosing the right slicer significantly impacts your results — even before you change a single printer setting.
First Project Ideas
The biggest beginner mistake is overreaching on your first few prints. The goal in the first month is to understand your machine — not to produce your magnum opus. These project categories are consistently recommended as high-success, high-motivation starting points.
FDM Starter Projects
- Calibration cube — Your very first print should always be a 20mm cube. Learn to read your printer's accuracy before printing anything else.
- Cable clips and desk organizers — Practical, small, fast to print, and genuinely useful. High motivation to finish and use.
- Cosplay props and masks — FDM excels at large, structural pieces. A plague doctor mask or helmet at scale is achievable within your first month.
- Terrain tiles for tabletop RPGs — Modular dungeon tiles are specifically designed for FDM. The scale and structural requirements are perfect for the technology.
- Replacement parts and household fixes — Broken shelf clip? Missing drawer knob? This is where 3D printing shows its real-world superpower.
Resin Starter Projects
- Single miniature character — Print one hero for your D&D campaign. Learn the full wash-cure workflow with low stakes and high reward.
- Ring or jewelry blank — Tests your printer's resolution and gives you a physical demonstration of what resin can do that FDM cannot.
- Pre-supported STL files — Search specifically for "pre-supported" files on Printables or MyMiniFactory. Your first prints shouldn't require you to master support placement yet.
Common Problems & Quick Fixes
Every 3D printer owner has a folder of failed prints. The difference between a frustrated quitter and a confident maker is knowing what the failure is telling you. Here are the most common beginner problems and their actual causes.
FDM Troubleshooting
| Problem | Most Likely Cause | Fix |
|---|---|---|
| Print won't stick to bed | Nozzle too far from bed, cold bed temp | Re-run bed leveling, increase bed temp, add a brim in slicer |
| Spaghetti / print collapses | Poor adhesion cascading into a full failure | Check first layer; that failed mini is now a dungeon floor piece |
| Stringing between parts | Retraction too low, temp too high | Increase retraction distance 0.5mm at a time; lower temp 5°C |
| Layer lines / poor surface | Normal for FDM — or too-high layer height | Drop layer height to 0.12mm; sand and prime for smooth finish |
| Warped corners (ABS/ASA) | Temperature differential, no enclosure | Add enclosure, increase bed temp, add large brim, switch to PLA while learning |
Resin Troubleshooting
| Problem | Most Likely Cause | Fix |
|---|---|---|
| Print stuck to FEP, not plate | Under-exposure on bottom layers; plate not level | Increase bottom exposure layers (4→8); re-level build plate |
| Supports failed mid-print | Support tips too thin or poorly placed | Use Lychee auto-support; manually add supports to flat overhangs |
| Layer separation / delamination | Under-exposure; cold resin in winter | Increase normal exposure time; warm resin to 25°C before printing |
| Print still soft/sticky after cure | Insufficient UV curing time | Add 2–3 more minutes per side in UV station; rotate the print |
Failed prints aren't failures — they're data. A veteran maker doesn't have fewer failures; they have faster feedback loops. Each failed print tells you exactly one thing to change. Change one variable at a time and you'll improve exponentially.
