The Complete Guide to 3D Printed Cosplay (No Printer)
Every 3D printed cosplay tutorial online assumes you own a printer, have 300 spare hours, and enjoy babysitting a machine at 2am. Most people building a costume have none of those things. What they have is a con date, a character, and a budget.
This guide covers the version where you never touch a printer: where the files come from, what a commissioned print run costs, how to scale pieces to your actual body, and the finishing work that decides whether the result looks like armour or looks like plastic. It is the whole process end to end, at overview depth. When you get to the point of choosing filament per piece and sending a maker your measurements, our deep dive on 3D printed cosplay armour covers fit, weight and material selection properly, and prices armour finished rather than raw.
How do you make 3D printed cosplay if you don't own a 3D printer?
Buy or commission the model files, pay a maker to print the pieces, and do the finishing yourself. Commissioned raw printing runs $450-1,200 for a full armour set and $120-250 for a helmet. Printing is the only step that needs a machine. Sanding, filling, priming, painting and strapping all happen at home with hardware-store supplies.

Key takeaways
- •A full 3D printed armour set is typically 150-350 hours of print time across 25-60 pieces, which is why commissioning the printing is now the common route rather than the lazy one.
- •Commissioned raw printing costs roughly $450-1,200 for a full set and $120-250 for a helmet as of July 2026, before finishing supplies and hardware, which are $110-300 at retail for a first build.
- •Finishing is about 80 hours of your own labour on a full set, on top of the machine time. Sanding and filling alone is 30-50 hours of it.
- •PLA or PLA+ is correct for nearly all cosplay armour. Reserve PETG for heat exposure and TPU for pieces that must flex.
- •Start three months before the convention for a full set. Filler primer and paint need cure time that cannot be compressed.
Step 1: Getting Files That Fit You
There are three routes to a file, and they cost wildly different amounts. Existing armour kits sold on Etsy, Gumroad, MyMiniFactory and creator storefronts run roughly $10-60 for a full set and are usually sold pre-split into printable chunks with alignment pegs. Free files exist but are usually single-piece models never intended to be worn, and re-cutting one for a print bed is real work. Commissioning an original sculpt is $300-1,500 and only makes sense for a character nobody has modelled.
The step everyone skips is scaling. A kit is modelled to fit whoever the sculptor had in mind, which is not you. Before anything gets printed, measure your chest circumference, shoulder width, forearm length and head circumference, and give those numbers to whoever is doing the slicing. Most kits scale uniformly by 5-15% either way without looking wrong. Beyond that you are into re-modelling.
One thing to check before commissioning: many cosplay kits carry personal-use licences that permit you to print them but not to have them printed commercially. Read the licence, and tell your maker what it says. Our own position is worth stating plainly, because it is not the industry norm: 3D Print Bounty does not accept jobs that require a maker to supply a copyrighted commercial sculpt they are not licensed to reproduce. That is why the makers here will ask about your licence rather than quietly quoting on anything you send.
Step 2: What the Printing Costs
Cosplay pieces are large, hollow and printed at low infill, so they eat print hours rather than filament. A helmet is typically 350-600g of PLA, which is $6.65-18 of material and 18-30 hours of machine time. That ratio is the whole story of cosplay print pricing: you are renting a machine, not buying plastic.
Typical commissioned print cost by piece (unfinished, PLA)
Print commissions for cosplay are priced by machine hours, so a full armour set at $450-1,200 costs several times a single prop even though it is not several times the material. These are raw prints; paying a maker to finish them as well takes a full set to $1,200-3,000.
| piece | Typical low | Typical high |
|---|---|---|
| Single prop | $40 | $150 |
| Helmet | $120 | $250 |
| Gauntlets + bracers | $90 | $220 |
| Chest + back plate | $150 | $400 |
| Full armour set | $450 | $1200 |

Two things reduce that number meaningfully. First, ask for a coarser layer height. Cosplay armour gets sanded and filled anyway, so 0.28 or 0.3mm layers cut print time substantially and cost you nothing you were not about to sand off. Second, ask for low-infill printing on non-structural panels. A shoulder pauldron does not need 15% gyroid infill; it needs three walls and nothing inside.

Step 3: Choosing the Material
The material question for cosplay has a boring answer and it is worth defending: use PLA or PLA+ for nearly everything.
| Material | Use it for | Watch out for |
|---|---|---|
| PLA / PLA+ | Helmets, pauldrons, chest plates, greaves, props. The default | Softens around 55°C. Do not leave a build in a parked car in summer |
| PETG | Pieces that travel in hot vehicles, or thin parts that flex in wear | Stringier, harder to sand smooth, and glossier under primer |
| TPU | Under-arm sections, boot cuffs, anything that must bend to get on | Prints slowly, will not sand, and paint cracks unless you use a flexible medium |
| ABS / ASA | Rarely worth it for cosplay | Warping on large flat panels is a real failure mode, and its acetone-smoothing advantage is undone by the filler primer you were going to use anyway |
Do not print everything. Fabric, straps and padding belong in fabric. EVA foam is still better than plastic for any large curved surface that sits directly against your body, because it is lighter and it forgives an imperfect fit. The strongest builds are mixed: printed hard-surface detail on a foam or fabric base.
Step 4: Finishing, Which Is Most of the Work
This is where builds die. The printing is done by a machine on someone else's schedule. The finishing is done by you, at night, after work, and it is roughly 80 hours on a full armour set.
The sequence that works: knock off support nubs and seams, glue pieces together with CA glue and reinforce the inside seams with an epoxy putty or fibreglass tape, fill the seams with a spot putty, then spray filler primer and wet-sand at 220, 400 and 600 grit. Two or three primer-and-sand cycles is normal. Then colour coats, weathering, and a matte or satin clear coat.
Time-saving that actually works: accept visible layer lines on textured surfaces. A weathered, battle-damaged finish hides layer lines completely, and a mirror-smooth painted finish shows every one you missed. Choose the paint scheme that matches the hours you have.
Where the hours go on a full 3D printed armour build
Machine time dominates the raw hour count, but every hour after printing is your own labour, and sanding plus filling alone is around 40 hours on a full set.
| stage | Hours |
|---|---|
| Printing (machine) | 220 |
| Support removal | 8 |
| Sanding + filling | 40 |
| Priming + paint | 22 |
| Straps + assembly | 14 |

Step 5: Making It Wearable for Eight Hours
The build that photographs well and the build you can wear all day are different builds. Four things separate them.
Weight distribution. Hang armour from a harness worn on the shoulders and hips, not from the piece next to it. Chains of glued panels tear themselves apart at a con.
Straps and hardware. Elastic webbing, Chicago screws and industrial hook-and-loop. Budget $30-60 in hardware for a full set. Print the strap anchor points into the pieces if you can, because glue-on anchors are the first thing to fail.
Ventilation and vision. Helmets get hot within twenty minutes. A 40mm computer fan and a battery pack costs under $20 and is the single best upgrade to any full helmet. Check your peripheral vision at floor level before the con, not at it.
Travel. Design around your suitcase from day one. Pieces that split at a seam and bolt together travel; a one-piece chest plate does not. If you are flying, check the convention's prop policy and your airline's size limits before you commit to a silhouette.
A Realistic Timeline
| Weeks before the con | What should be happening |
|---|---|
| 12-14 | Files bought, body measured, scaling decided, print commission posted |
| 8-11 | Printing runs. Buy sandpaper, filler primer, glue, hardware now, not later |
| 5-7 | Assembly, seam filling, first primer coats, first test fit |
| 3-4 | Paint, weathering, clear coat. Paint needs days to cure hard, not hours |
| 1-2 | Straps, padding, a full-day wear test at home, and the repairs that test reveals |
Frequently asked questions
Can you do 3D printed cosplay without owning a printer?
Yes, and it is the normal route now. You buy or commission the model files, pay a maker to print the pieces, and do the finishing and assembly yourself. Printing is the one step that genuinely requires a machine. Sanding, priming, painting and strapping all happen at your kitchen table with hardware-store supplies.
How much does a full 3D printed cosplay build cost?
Commissioned raw printing for a full armour set typically runs $450-1,200 depending on coverage and size, a helmet alone $120-250, and a single prop such as a sword or gauntlet $40-150. Add $110-300 for finishing supplies and hardware at retail. Files are $10-60 if you buy an existing kit rather than commissioning a sculpt. Paying a maker to finish the set as well takes it to $1,200-3,000.
How long does it take to 3D print a cosplay suit?
A full armour set is typically 150-350 hours of print time spread over 25-60 separate pieces, which is one to three weeks of near-continuous printing on one machine. Printing is unattended; finishing is not. Budget roughly 80 hours of your own hands-on work after the parts arrive, which is where builds actually run late.
What material should cosplay armour be printed in?
PLA or PLA+ for almost everything, because it is cheap, rigid, sands well and prints large flat panels reliably. PETG is worth it for pieces that will sit in a hot car or take repeated flexing. Use TPU only for parts that must bend, such as under-arm joints and boot cuffs. ABS is rarely worth the warping risk on big panels.
When should I start a 3D printed cosplay for a specific convention?
Three months out for a full armour set, six weeks for a helmet and a prop. Printing is the predictable part; finishing is what runs over. Start eight weeks out on a full set and you are likely to arrive with unpainted pieces or wet paint, because filler primer and paint both need cure time you cannot compress.
Get Your Build Printed
Post your files, your measurements and your con date. Makers who have printed armour before will bid with a delivery date, and your payment stays in escrow until you have approved photos of the finished pieces.
