3D printing, matched to your part by an engineer — not a menu you pick from.

FDM, SLA and SLS for prototypes, jigs, fixtures and low-volume functional parts. An engineer matches process and material to what your part actually needs to do, then nests it with the rest of your order to cut cost — quoted and owned by one engineer from start to finish.

Quick definition

3D printing (additive manufacturing) builds a part layer by layer straight from a 3D file, instead of cutting it from solid stock or injecting it into a mold. FDM extrudes melted plastic filament, SLA cures liquid resin with light, and SLS fuses nylon powder with a laser — no tooling and no minimum order, at the cost of losing to CNC or molding once a part needs real strength, a tight tolerance or high volume.

Proof, not a claim

Raced at the Tour de France on a 3D-printed part.

A maker of carbon TT bars needed a 3D-printed support mount with threaded inserts to fit-test with the rider before final production — the setup then raced at the Tour de France and the Giro d'Italia.

SLS 3D-printed PA12 nylon bracket, matte finish, no visible support marks
Printed in PA12 nylon (SLS) — no support scars, strong enough to use as a functional part, not just a look-alike.
SLA resin 3D-printed prototype part with a smooth, cosmetic-grade surface finish
Printed in SLA resin — smooth enough to pass as an injection-molded part in a form and fit check.

Priced by a person, not a pricing engine

Instant 3D printing platforms price the file. They don't nest the build.

Upload a file to most 3D printing marketplaces and an algorithm prices it part by part — bounding box, volume, technology — then ships from whichever printer in the network has capacity that week, with no one checking whether FDM, SLA or SLS is actually the right call — and anything the parser chokes on simply comes back unquotable. Send the same file to OperGo and an engineer matches the process to the part, nests it against the rest of your order to cut cost, and owns it start to finish.

Algorithmic 3D printing quoting
  • Technology picked by you upfront, not matched to what the part actually needs
  • Priced part by part — no credit for sharing a build plate with the rest of your order
  • File forwarded to whichever printer in the network has capacity that week
  • A support ticket to argue with if the material or finish shows up wrong
The OperGo way
  • Matched to the right process — FDM, SLA or SLS — by an engineer, not a dropdown
  • Nested and packed with the rest of your order to bring cost per part down
  • Every print quality-checked against the same standard, whichever technology runs it
  • One engineer owns your print from quote to the next reorder

What we run

Three processes, matched to the part in front of us.

FDM — Fused Deposition Modeling

The economical default for jigs, fixtures and early-stage prototypes in PLA, PETG, ABS or nylon — strong, fast and the cheapest way to hold a part in your hand.

SLA — Stereolithography

Smooth, cosmetic-grade resin parts for form and fit checks or presentation models — finer detail than an FDM layer line can show.

SLS — Selective Laser Sintering

Nylon powder parts strong enough to actually use, with no support structures — complex or nested geometry costs the same as a simple part.

Matched to your part, not a dropdown

Not sure which of the three fits? Send the file and an engineer matches process and material to what the part needs to do — cost, cosmetics or real mechanical strength.

Under one quote

Matched, nested and owned by one engineer.

FDM, SLA and SLS are matched to your part, nested with the rest of your order to bring cost down, and owned by one engineer from quote to delivery — the same standard as every other process we run.

One engineer, one invoice

Your part keeps one owner from quote to delivery — one quote and one invoice for the whole job, not a separate line per technology.

Nested to cut cost

Parts packed onto the same build plate as the rest of your order, not priced part by part.

ISO 9001:2015 certified

The same certified quality system covers every 3D printed order, the same as CNC or injection molding.

The spec sheet

Technologies, materials and tolerances.

Technologies & materials · 3D printingISO 9001:2015
FDMPLA, PETG, ABS, ASA, TPU (flexible) and PA12 nylon, optionally glass- or carbon-filled. Typical tolerance ±0.5% of the dimension (±0.5mm minimum) — the most economical process, best for jigs, fixtures and early prototypes.
SLAStandard, tough/ABS-like, clear, flexible and high-temp resins, plus castable resin for investment-casting patterns. Typical tolerance ±0.2% (±0.1mm minimum) — the finest surface finish and detail of the three.
SLSPA12 and PA11 nylon, glass-filled PA12, and flexible TPU powder. Typical tolerance ±0.3% (±0.3mm minimum) — no support structures, so complex or nested geometry costs the same as a simple part.
FinishingSanding, bead or vapor smoothing, dyeing (SLS) and primer, paint or clear coat — specified at quoting and confirmed against the exact material and partner running the job.
Batch sizeFrom a single validation print to a low-volume batch — usually the fastest bridge between a CAD file and a part you can actually hold or test.

Picking a process

3D printing is the right call — until it isn't.

3D printing vs. CNC machining →

3D printing wins on speed and freeform geometry no cutting tool can reach. CNC wins the moment the part needs real metal strength, a tolerance a printer can't hold, or a finished surface.

3D printing vs. injection molding →

3D printing has no tooling cost and no minimum order — exactly why it stops being the cheaper option once volume or unit-price targets call for thousands of identical parts off a mold.

Still not sure which technology?

Send the part and an engineer matches it to the right technology — FDM, SLA or SLS — based on what it actually needs to do, not a dropdown you fill in before seeing a price.

3D printing, answered

What's the difference between FDM, SLA and SLS 3D printing?

FDM extrudes melted plastic filament layer by layer — the most economical option, good for jigs, fixtures and early prototypes where cosmetic finish doesn't matter. SLA cures liquid resin with light, giving the smoothest surface and finest detail — the pick for form and fit checks or presentation models. SLS fuses nylon powder with a laser and needs no support structures, producing parts strong enough to actually use, including complex or nested geometry. An engineer matches the part to the right one rather than asking you to choose upfront.

What's included in a 3D printing quote — just the print itself?

No — your engineer matches the right technology (FDM, SLA or SLS) to your part, nests it with the rest of your order to cut cost, and owns it through delivery. You get one quote and one invoice for the whole job, not a separate line for material, technology and finish.

What's the minimum order quantity for 3D printing?

One — usually the fastest, cheapest way to get a single validation part in your hands before committing to CNC tooling or a mold.

How fast can I get a 3D printed part?

As little as 48 hours for a handful of parts, across all three processes — the fastest turnaround of anything we quote. Larger batches take longer; your engineer confirms a real date at quoting, not a range.

Can I get an instant price online?

Not yet — every 3D print is still priced by an engineer, the same as every other process we run. What that buys you: your parts get nested onto a shared build plate with the rest of your order instead of priced one at a time, which is usually cheaper than what an automated per-part calculator would quote.

What tolerances can 3D printing hold?

Standard for the industry and the machines running the job: roughly ±0.5% on FDM, ±0.2% on SLA and ±0.3% on SLS, each with a sensible per-process minimum. If your part needs tighter than that on specific features, CNC is usually the better call.

What if 3D printing isn't the right process for my part?

Then your engineer says so at quoting. If you need real metal strength, a tolerance a printer can't hold, or a volume where per-part cost needs to come down, they'll requote it under CNC or injection molding instead. Opening this page doesn't commit you to a process.
