Will it print? Find out before you pay.

Pick a part and a process. The fabgen engine checked each test file the way a print service would — closed mesh, walls, overhangs, cavities, machine size — and tells you what to fix, with numbers.

Your model file is never uploaded anywhere. How?

Mushroom · FDM

Input: mushroom.stl · FDM · 30 × 30 × 15 mm · 5.5 cm³

Printable Can be printed as modeled.

Mesh: Closed
Thinnest wall: 5.0 mm needs ≥ 0.8 mm
Support material: 1.2 cm³ 8.0 cm² steeper than 45° with +Z up
Sealed cavities: 0
Smallest machine: desktop printer
Mass with supports: 6.2 g PLA

Assumptions, warnings and sources

Warnings

LowAbout 8.0 cm2 overhangs steeper than 45 deg with +Z up: supports needed (scars on those surfaces).
NotePrinting with -Z up needs less support (0.0 vs 1.2 cm3).
LowSome rules and figures are not yet re-checked against their primary source, or are fabgen planning assumptions. They are flagged “data under review”.

Assumptions

Wall thickness is sampled, not exhaustive: thin features between samples can be missed.
FDM material = 1.2 mm shell (perimeters and skins) + 20% infill of the rest.

What printing it may cost

The mushroom part, priced across three classes of service and four processes. The spread is the point: the same part costs very different money depending on where it is made.

A typical PCB: price and design rules

Two layers, 100 × 80 mm, ten boards. The engine checks your design minimums against what each class of fab can make, then estimates bare boards with shipping.

Engine examplefabgen.pcb_quote_estimate/1Data under review

PCB estimate and DFM

Input: 2 layers · 100 × 80 mm · 10 pcs · 1.6 mm · HASL · delivery: USA

Bare boards with shipping: $23 to $491 depending on the class of fab. Components are never priced. Not a quote.

Prototype fab in China: $23–$51 $2.33–$5.13 per board · 4–11 days
Domestic US/EU prototype service: $260–$491 $26.00–$49.10 per board · 6–17 days

DFM checklist before you export

Keep copper at least 0.3 mm from a routed edge and 0.5 mm from a V-score (JLCPCB minimum 0.2 / 0.4 mm).
Silkscreen lines at least 0.15 mm wide and text at least 1.0 mm high, 0.15 mm clear of pads.
Solder-mask web between fine-pitch pads needs about 0.1 mm (0.13 mm for black or white mask); otherwise ask for gang relief.
Boards smaller than about 20 x 20 mm, or for assembly, are cheaper and safer as a panel with rails.
For machine assembly add 2-3 global fiducials and keep 3-5 mm rails or clearance at the edges (JLCPCB asks for 5 mm rails and 1 mm fiducials).
Send one closed board outline on its own layer; internal cut-outs at least 1 mm wide.
Export Excellon drill files with plated and non-plated holes separated and units stated.

DFM checklist before you export

Keep copper at least 0.3 mm from a routed edge and 0.5 mm from a V-score (JLCPCB minimum 0.2 / 0.4 mm).
Silkscreen lines at least 0.15 mm wide and text at least 1.0 mm high, 0.15 mm clear of pads.
Solder-mask web between fine-pitch pads needs about 0.1 mm (0.13 mm for black or white mask); otherwise ask for gang relief.
Boards smaller than about 20 x 20 mm, or for assembly, are cheaper and safer as a panel with rails.
For machine assembly add 2-3 global fiducials and keep 3-5 mm rails or clearance at the edges (JLCPCB asks for 5 mm rails and 1 mm fiducials).
Send one closed board outline on its own layer; internal cut-outs at least 1 mm wide.
Export Excellon drill files with plated and non-plated holes separated and units stated.

A small CNC bracket, before and after

Five features of an aluminium bracket, each with a verdict and the reason. Switch to see what the fixes change.

Engine examplefabgen.cnc_check/1Data under review

Aluminium bracket, as drawn

Input: AL6061 · 60 × 40 × 20 mm · 5 pcs · 5 features

Not feasible 0 fine, 4 drive the price up, 1 cannot be machined.

ImportantAt least one feature cannot be machined as drawn: see `features`.

PocketCostly
- OK Depth is 0.6x the narrowest width (recommended up to 4x, long tools up to 10x).
- Costly Needs a 3.00 mm tool reaching 4.0x its diameter: slow, long-reach cutting. Increase the radius if you can.
Side wallCostly
- Costly 0.6 mm wall in metal: recommended at least 0.8 mm, feasible 0.5 mm (thin walls vibrate and deflect while cutting).
Mounting holeCostly
- OK Diameter 5.0 mm (recommended at least 2.5 mm with standard drills, feasible 0.5 mm with micro drills).
- Costly Depth is 6.0x the diameter: deep drilling with pecking.
M4 threadCostly
- Costly M4: M6 and larger are cut with standard taps; down to M2 with care (tap breakage risk).
- OK Thread longer than 3x the diameter adds no strength; shortening it saves machining time.
Bore fit toleranceNot feasible
- Not feasible +-0.02 mm: standard machining holds +-0.125 mm; tighter down to +-0.025 mm needs slower passes and inspection.

OK Part 60 × 40 × 20 mm — fits a typical 3-axis mill

Your model file never leaves your computer

fabgen reads the STL or 3MF from a local path on your machine. The file is never uploaded anywhere — not to us, not to a print service. The examples on this site were computed the same way, from the engine's own test files.

The check runs locally, without the network.
When offers open, only a job summary goes out: process, material, quantity, sizes. No file, no name, no contacts.
You upload the file yourself, on the service's own page, when you decide to order.

Ranges, never a quote

fabgen does not sell printing and shows no sponsored services. A real price comes from the service's own quote, after you upload the file there yourself.

Partners are not connected yet. When they are: neutral order, your contacts go only to the partner you name and only with your consent. How we make money

When offers open, you upload the file only on the service's own page. fabgen never sends it.

Questions makers ask

Why does my part need supports?

Faces that hang steeper than the process allows print in the air. In the engine example the mushroom needs about 1.2 cm³ of FDM support as modeled; turned −Z up it needs none.

How thin can a wall be?

It depends on the process. The 0.4 mm test plate measures 0.4 mm against an FDM minimum of 0.8 mm, so the engine asks for changes. Resin and powder processes have their own minimums, shown on the page.

Why can a hollow part fail in resin but not in filament?

A sealed cavity traps liquid resin or loose powder. The test cube has 1 sealed cavity: FDM prints it, SLA, SLS and MJF need escape holes or a solid part.

How much does 3D printing cost?

For the mushroom part, 10 pieces delivered to the US, the engine gives order totals from $21 to $710 across service classes and processes. These are ranges from published calculators, not a quote.

How much do 10 two-layer PCBs cost?

For a 100 × 80 mm board the engine gives $23 to $491 with shipping, depending on the class of fab. Components and assembly parts are not priced.

Is my file uploaded?

No. The engine reads the file locally and never uploads it. When offers open, only a summary of the job is passed on; the file is uploaded by you, on the service's page.

Will it print? Find out before you pay.
