FabDigit
Engineering Consultancy

Engineering as a service. Connected to the cell that builds it.

Three engineering practices under one roof: part & assembly design, equipment & automation design, and Li-ion battery technology & pack design. Sold by the engagement, not the head — and connected to a manufacturing cell so the DFM is honest because the consequence is the next part list.

The three pillars

Three engineering practices. One way of working.

The throughline across the three: a named engineer, fixed-scope deliverables, and a manufacturing cell two doors down that builds whatever the engineering practice specs. No bait-and-switch on the senior engineer, no markup on hours.

Pillar 01

Part & Assembly Design

Mechanical engineering as a service.

Part design, assembly design, DFM, tolerance stacks, and finite-element review for the parts a FabDigit cell will eventually build. Embedded ME on staff for the engagement; CAD lives in your tree, drawings ship in your title-block.

Pillar 02

Equipment & Automation Design

Machines that build the things you build.

Custom equipment, fixtures, jigs, and end-of-line automation for the production lines that ship your parts. We co-design with your production engineer, build at our partner cells in Shenzhen, and FAT (factory-acceptance-test) in our shop before the line ships.

Pillar 03

Li-ion Battery Technology & Pack Design

Cell to module to pack — the full chain.

Six engineering disciplines that touch a battery program: cell-level R&D, electrode chemistry, BMS architecture, thermal + pack integration, manufacturing engineering, and safety / certification. The full deep-dive lives on the dedicated LiB Consultancy page.

How we engage

Three engagement modes, sized to the problem.

The same engineer can move between modes as the engagement evolves — a discovery call this month becomes an embedded sprint next quarter and a retainer for the production ramp after that.

Mode 01

Discovery call

Free 45-minute call with the engineer who would lead the engagement, not a sales lead. We diagnose the problem, sketch the engagement shape, and tell you whether we're the right team for it.

Schedule a discovery call
Mode 02

Embedded engineering sprint

4 – 12 week fixed-scope engagement with a named engineer embedded in your CAD tree, slack, and meeting cadence. Deliverables defined in week 1, signed off in the final week.

Scope an embedded sprint
Mode 03

Retained engineering practice

6 – 12 month retained engagement at 0.5 – 2 FTE-equivalent. The engineer becomes the hardware lead for the program; we ship the parts they spec from the same cell. No double-charging.

Set up a retainer
Pillar 01

Part & Assembly Design

Part design, assembly design, DFM, tolerance stacks, and finite-element review for the parts a FabDigit cell will eventually build. Embedded ME on staff for the engagement; CAD lives in your tree, drawings ship in your title-block.

Deliverables
  • CAD / STEP / parametric SolidWorks or Onshape
  • Drawing pack (GD&T, tolerance stack, BoM)
  • DFM review against your target process
  • FEA: stress, modal, thermal, fatigue
  • Material + finish selection memo
  • Cost estimate vs alternative processes
Who this fits
  • Mid-stage start-up scaling an MVP into a real BoM
  • Larger team needing surge engineering for a deadline
  • Existing program that needs a part-cost reset
  • Pre-IPO hardware company sealing a Series-D BoM
Pillar 02

Equipment & Automation Design

Custom equipment, fixtures, jigs, and end-of-line automation for the production lines that ship your parts. We co-design with your production engineer, build at our partner cells in Shenzhen, and FAT (factory-acceptance-test) in our shop before the line ships.

Deliverables
  • Concept + simulation (Visual Components / Process Simulate)
  • Mechanical + electrical CAD package
  • PLC / control architecture (Beckhoff, Siemens, Rockwell)
  • Vision / metrology integration (Cognex, Keyence, Halcon)
  • FAT + SAT protocols, sign-off documentation
  • Field commissioning + 6-month warranty support
Who this fits
  • Volume program needing a custom line (e.g. battery pack assembly)
  • Lab-scale process moving to pilot production
  • Existing line needing a take-out / repeat-build replica
  • End-of-line automation retrofit on an installed line
Pillar 03

Li-ion Battery Technology & Pack Design

Six engineering disciplines that touch a battery program: cell-level R&D, electrode chemistry, BMS architecture, thermal + pack integration, manufacturing engineering, and safety / certification. The full deep-dive lives on the dedicated LiB Consultancy page.

Deliverables
  • Cell-level R&D + chemistry recommendation
  • BMS architecture + protection design
  • Pack thermal integration (cooling plate, IFP, heat dissipation)
  • UN38.3, IEC 62133, GB 38031 certification support
  • Pilot-line manufacturing engineering
  • Field warranty + return-stream forensics
Who this fits
  • EV start-up bringing first pack from cell to production
  • ESS operator scaling from a single MWh to a 100-MWh fleet
  • OEM scaling from CKD pack imports to local-content packs
  • Defence / aerospace battery program with cycle-life targets

Frequently asked

The questions heads-of-hardware keep asking us.

  • Two ways. First, the engineer who would do your work also has access to the cell that would build it — DFM is honest because the consequence is the next part list. Second, we don\'t resell engineering hours at a markup; the engagement price is what the engineer is paid for that block of time, scoped against deliverables, not against head-count.

  • Always. NDA signed before any CAD changes hands; mutual NDA with carve-outs for general industry knowledge. We can sign your NDA or ours.

  • Yes, for engagements over $250 k we can dispatch an engineer on-site for the duration. Common patterns: 1 week / month on-site for the first 3 months, then remote with quarterly check-ins.

  • Selectively, for early-stage programs whose hardware is going to live in our cells anyway. We typically structure it as a discount on the engagement + a SAFE on the next priced round, not as direct cash-for- equity.

  • You do. Engagement contracts assign work-product IP to the client at deliverable acceptance. Background IP (FabDigit-developed tooling libraries, internal know-how) stays with us; foreground IP (the thing we built for you) is yours.

  • Yes — that\'s the entire pitch. Drawings finish in our engineering tree, drop into our quote engine, and ship from the same cells. One PM through the whole loop.

Pick a pillar. Or send a problem statement.

Either way you'll have the engineer who would actually do the work on a call within a week. No sales lead, no markup, no bait-and-switch.
