The DTSS-3D standard

Managing the network that powers DTSS-3D

With DTSS-3D, you get access to a network of experienced, specialised manufacturers selected for operational excellence. Our network has the capabilities and capacity to handle any custom parts, giving you complete design freedom and a more resilient manufacturing supply chain.

Maintaining the quality of an entire network

We work with a highly vetted network of around 300 manufacturing partners (MPs) and hold each of them to the highest quality standards. To ensure all MPs uphold the DTSS-3D standard, we’ve developed comprehensive systems for selecting and supporting our suppliers. We continually audit our protocols to guarantee we deliver quality parts, every time.

How we select and onboard suppliers

Our network of experienced, specialised suppliers gives us our breadth of capabilities and consistent quality. DTSS-3D has a strict selection and onboarding process for managing and growing this network. For every new supplier we bring onto the network, we use a comprehensive 8-step process:

Initial outreach

We approach suppliers we believe meet our standard to gauge interest and assess the match.

First evaluation

We conduct an evaluation to see if the supplier meets DTSS-3D’ qualification criteria. We also provide detailed information on what it’s like to work with DTSS-3D.

Factory audit

A DTSS-3D auditor assesses quality management performance and environmental/social compliance.

Legal due diligence

Every DTSS-3D supplier has to hold the right registrations and licenses. We do full background checks and sign formal agreements to ensure compliance.

Platform access

Once suppliers meet our standards, we give them access to the quote-building platform.

Technical training

To ensure the process runs smoothly from ordering to delivery, we train every MP on the technical standards, logistics and communication requirements behind the platform.

First 10 orders

Supply chain managers monitor the first 10 orders of every new supplier. We perform on-site quality control for pre and post-production.

Quality assurance

To ensure that our network meets and exceeds industry standards, we audit our MPs on a regular basis and drive continual improvement.

How we audit our suppliers

Manufacturing partners must consistently prove their quality after joining the network. We conduct audits every two years to ensure consistent quality across our network. These audits include quality audits to test capabilities and quality control, and social audits, to confirm environmental and social compliance. We also do frequent spot checks at our major sites.

Quality Management & Quality System
  • Certifications (ISO/AS)

  • Quality organization

  • Quality policy & objectives

  • Raw material (in & out record dates & Qties)

  • Manufacturing process records

  • Requirement level for suppliers/subcontractors

Social audit
  • Safe hiring practices and workplace protections

  • Discrimination

  • Fair working hours, wages and remuneration

Reception/Incoming Quality Controls
  • Identification of incoming materials

  • Quality control on incoming materials and records

  • Incoming and outgoing management (FIFO)

Production & Packaging
  • Identification of batches of ongoing orders

  • Machines & manufacturing equipment

  • Quality controls during production

Master packaging & Storage/FQC
  • Identification of finishes products/parts

  • Inspection of finished product

  • Health and safety conditions

We are always improving. Here is how we do it.

We aim to keep our line item non-conformance rate below 1% and minimize part issues. If issues do arise, a corrective action plan goes into effect. The MP involved finds the root cause of the issue and improves the process to ensure similar problems do not arise in the future. 

To make sure your parts are made up to spec, our MPs adhere to our DTSS-3D Manufacturing Standards.

Ensuring quality locally and globally

Our platform lets you choose between local and international manufacturing options. Local sourcing is typically faster, but more expensive. All 3D printing and some CNC orders are sourced locally, quality checked by the manufacturer and sent directly to you.

International sourcing is typically more economical. Certain complex CNC machining, injection molding and sheet metal orders can only be sourced globally, and we cover the cost of clearing customs for these orders. Depending where they’re manufactured and how complex the parts are, globally sourced orders are first shipped to our cross-docking facilities in Amsterdam or Chicago for QC inspections, before shipping out to their final destinations.

Local Overseas
Part quality Good (The DTSS-3D standard) Good (The DTSS-3D standard)
Capabilities More narrow Broad range
Time to parts in hands Faster Slower
Pricing Higher Lower
Shipping time Shorter (low variance) Longer (high variance)

Quality control for parts sourced

All parts are thoroughly inspected by the manufacturing partner according to our guidelines. Depending on part complexity and the manufacturing location, some orders also undergo a second inspection at our cross-docks in Amsterdam or Chicago.

Customers in the US and EU can choose to have their CNC orders sourced through manufacturing partners (MPs) within their custom-clearance borders. Our MPs perform QC inspections, then send the parts directly to you, resulting in fewer logistical hurdles and much faster delivery times. Find out more about local CNC machining.

Customers will be notified if their orders deviate from this standard supply chain flow. For more information, contact the Customer Success Team at
