Who Has the Keys to Your Factory? Why Role-Based Access Control (RBAC) is Non-Negotiable for Scaling Additive

When you’re evaluating a 3D printer, the focus is naturally on the physical: What can it make? How strong is the part? How fast is the print?

But the most critical question isn't just about the part; it's about the process. As you scale, you must ask: How will I manage it?

If you have one or two printers today, your management system might be a shared login. It might be a password on a sticky note. But the keys to your factory are too important to leave on a sticky note.

For a single printer in an R&D lab, that's a minor risk.

When you're scaling to 5, 10, or 50 printers across multiple facilities, that sticky note isn't just a risk. It's a full-blown security, quality, and operational liability.

What happens when an intern accidentally prints a 100-hour, unvetted prototype using an entire spool of your most expensive material? What happens when a well-meaning operator on the floor tweaks a part file, breaking its design integrity?

Suddenly, your factory of the future is in chaos. To scale, you don't just need more printers; you need more control.

That control starts with one essential feature: Role-Based Access Control (RBAC).

What is Role-Based Access Control?

Role-Based Access Control is a security feature that lets you assign specific permissions to specific users.

Think of it like the keys to your factory.

• The IT Director has a master key that can open any door and change the locks.
• The Plant Manager has a key that opens the production floor and the parts warehouse.
• The Machine Operator has a key that only turns on the machines they're assigned to.
• The Engineer has a key to the R&D lab to design the parts, but not to the production floor.

You would never give everyone in the building a master key. So why would you give every user Admin access to your entire digital manufacturing operation?

Why RBAC is Your Key to a Secure, Scalable Factory

RBAC isn't just a nice-to-have IT feature. It's the foundational building block for solving the three biggest challenges of scaling additive manufacturing.

1. It Solves Your Security & Trust Problem

When you buy a Markforged printer, you're not just buying a piece of hardware; you're connecting a sophisticated network endpoint to your corporate infrastructure. Your IT and security teams know this, and they're right to be cautious.

RBAC is a major piece to answer their tough questions:

• It Kills the Shared Password: In Eiger, you don't share logins. Every user has their own unique account, which can (and should) be tied directly to your corporate Single Sign-On (SSO) system. If an employee leaves, you deactivate their account, not change the password on every printer.
• It Creates a Digital Audit Trail: Because everyone has a unique login, you get a full, unchangeable record of who did what, when. When an auditor for an ISO, AS9100, or FDA-regulated process asks, "Who approved, printed, and verified this part?" you can give them a definitive, traceable answer.
• It Enforces the "Principle of Least Privilege": You can give your R&D intern the ability to upload and slice a part file without giving them the ability to delete your entire corporate part library or change printer network settings. This isn't about mistrust; it's about smart, preventative security.

2. It Solves Your Operational Scale Problem

Managing a global fleet of printers from a single, shared admin account is impossible. RBAC is what turns your printers into a unified factory.

• It Enables Distributed Manufacturing: You can confidently place a printer in your Michigan facility, create an Operator role for the local team, and know they can print the parts you send them—but they cannot see or print the proprietary R&D files being designed in your Boston HQ.
• It Protects Your Digital Inventory: You can designate a few Managers as the only people who can upload and approve new files to your "Golden" part library. This creates a single source of truth, ensuring that operators can only print the most current, approved, and validated version of a part.

3. It Solves Your Factory-Ready Quality Problem

A factory-ready part isn't just about strength; it's about process. It's about guaranteeing the part you print is the part you designed.

• It's the Gate for Your Workflow: RBAC is the engine behind our Part Approval Workflow. You can set up a system where an Engineer can submit a part, but it cannot be printed until a Manager approves it.
• It Prevents Bad Prints: This digital gate is what stops an untested, prototype-level file from being printed and used as a production-ready tool. It prevents accidental part failures and stops material waste. It’s the difference between printing a part and printing a part you can trust.

Control Isn't a Barrier. It's an Enabler.

We often think of security and control as things that slow us down. In a scaled additive operation, the opposite is true.

• Control (RBAC) builds Trust (IT & Security).
• Trust enables Scale (Your Global Fleet).
• Scale delivers Factory-Ready Parts (Your ROI).

Without control, you can't have trust. Without trust, you'll never be allowed to scale.

When you're evaluating a 3D printer, you must go beyond what it can make and, as we've said, ask how you will manage it. The keys to your factory demand a real lock, not a sticky note.
