Build the kit, or print the parts
This has become a real decision only recently, and it is asked constantly and answered badly — usually as though printing were simply a cheaper way of getting kits. It is not. A kit is a solved problem: the parts fit, the proportions are right, and everything you contribute is craft applied to somebody else’s engineering. A printer solves nothing and enables everything, and the skill it asks for is orientation, supports, tuning and failure diagnosis rather than knife work and paint. The finishing is the same on both, which is the part that surprises people.
The decision this settles: You want small, detailed physical objects on a shelf — models, terrain, figures, parts for something else. You are deciding whether to buy kits and build them, or buy a printer and make your own, and the two answers cost about the same to begin.
Where they genuinely differ
Marked per row rather than overall — “better” only means something relative to a specific dimension.
| Point of difference | Scale modelling | 3D printing |
|---|---|---|
| Where the difficulty isThe printer adds a whole engineering stage before the craft stage; it does not remove the craft stage. A printed part still needs cleaning up, priming and painting. | Assembly and finishing — seams, fit, paint, and the patience to do the boring stage properly | Getting the machine to produce a good part reliably, then the same finishing as the kit |
| What you can actually makeThis is the axis that decides it for most people who choose printing. If you want a specific building, an out-of-production subject or a part that does not exist, no amount of kit-building gets you there. | Whatever has been kitted, which is an enormous back catalogue and does not include the thing you invented | Anything you can model or find a file for, at any scale, in any quantityAdvantage here |
| Surface quality out of the boxThe honest version of a much-argued point: resin printing has closed most of this gap for figures and small parts, and filament printing has not — but resin brings uncured photopolymer, solvent washing and ventilation requirements with it. | Injection-moulded detail that is still, for fine work, better than most consumer printingAdvantage here | Layer lines on filament; genuinely excellent on resin, at the cost of a much messier and more hazardous process |
| Cost shapePrinting wins on quantity by a wide margin, which is why it took over wargaming terrain almost completely and has barely touched one-off display modelling. | Per object, forever. A good kit is £20–£60 and the next one costs the same | A large fixed cost, then very little per object — a spool makes a great deal of terrain |
| Time before the first finished thingA printer is a hobby before it is a tool. That is a feature for some people and the whole objection for others. | An evening or two. The kit worksAdvantage here | Longer, and unpredictable — first-layer problems, adhesion, supports, and the calibration that everybody underestimates |
| What it demands of a roomFilament printing is a benign neighbour. Resin printing is not a spare-bedroom activity and is frequently treated as one. | A table, a cutting mat, and somewhere to sprayAdvantage here | A machine running for hours, with noise, heat, and — for resin — real ventilation and chemical handling |
Scale modelling
Somebody who wants the craft, and wants to be finishing something this weekend
Kits give you the hand skills — cleaning up, seam work, painting, weathering — with none of the machine problem in front of them. The catalogue of available subjects is vast, and the failure modes are all yours to fix rather than a machine’s.

Somebody who wants specific things, or many of them, and does not mind the machine being part of the hobby
A printer is the right answer when what you want does not exist as a kit, when you need forty of something, or when designing the object is itself the appeal. Budget for the calibration phase, and think about resin ventilation before buying rather than after.
More on 3D printingThe finishing is identical and it is where most of the visible quality comes from. Priming, paint, washes and weathering behave the same on a moulded part and a printed one, and somebody who is good at that on kits is immediately good at it on prints.
A great many people end up doing both, and the split is usually by subject rather than by preference: printing for terrain, bases, jigs, spares and anything unavailable; kits for the aircraft, ship or vehicle they actually wanted to build.
