About HEFF 3D Tech

Built for Engineers.
Open to Everyone.

We are a precision additive manufacturing service based in Delhi. We work with hardware companies, OEMs, architects, designers, and individual builders. Engineering oversight, confidential file handling, and honest process advice on every order.

Our Vision
Precision manufacturing with engineering depth. Accessible to anyone who needs it. In a market where most services take your file and run it, we review geometry, advise on process, and treat every project with the same engineering rigour regardless of scale or industry.

Our Mission

What we do, who we serve, and what we commit to on every project.

Precision additive manufacturing for hardware teams and creative professionals. Engineering depth on every project, regardless of scale.

We work across the full spectrum of additive manufacturing: from engineering-grade functional prototypes and batch production runs for hardware companies, to architectural models, display pieces, and bespoke fabrication for designers and creative professionals.

What stays constant across every project is the standard we hold ourselves to. Advanced materials, confidential file handling, and manufacturing expertise that goes beyond slicing a file and shipping a part.

Who We Are

HEFF 3D Tech is a Delhi-based additive manufacturing service founded on one principle — that access to precision manufacturing should not depend on minimum order quantities, large procurement teams, or established vendor relationships.

We run a fleet of FDM printers operating 18 to 22 hours daily, with in-house engineering oversight on every job. Whether you are a Startup sending your first CAD file or an OEM sourcing batch production, you get the same engineering rigour, the same documentation protocols, and the same commitment to getting it right.

Our consulting capability across all AM processes means we will tell you which process is right for your application, even if it is not one we run in-house.

Engineering & Technical

Hardware, OEMs & Product Development

Full-Cycle prototyping, DfAM consultation, and batch production for hardware Startups, OEMs, and R&D teams. Every project handled with the same confidentiality protocols regardless of size.

Creative & Commercial

Design, Architecture & Custom Fabrication

Custom fabrication for architects, designers, event professionals, and creative studios. The same engineering rigour that makes functional prototypes reliable is what makes architectural models and bespoke pieces precise. Complex geometries and short runs are where we work best.

For Everyone

If Traditional Methods Won't Work

If conventional manufacturing cannot solve your problem: minimum order quantities, geometry too complex for machining, or timelines too tight for a factory. Additive manufacturing is likely your answer. Talk to us before you assume it cannot be done.

Our Values

Three principles that govern how we work on every project, regardless of scale or client type.

01

Versatility Without Compromise

We serve diverse industries and project types without diluting quality. A bespoke architectural model receives the same engineering attention as a functional prototype.

02

Confidentiality as Standard

Your intellectual property, design files, and project concepts are protected from the first conversation. Secure file handling, discretion, and NDAs are not premium add-ons. They are how we operate.

03

Honest Expertise

We will tell you when AM is not the right solution for your project, recommend better processes when they exist, and never oversell our capabilities. We are the engineering partner, not a vendor optimising for order volume.

Why HEFF 3D Tech?

What separates us from a 3D print shop and why it matters for your project.

01
Engineering Oversight on Every JobEvery project is reviewed for manufacturability, build orientation, material selection, and tolerance before production begins. We catch problems in CAD before printing.
02
Physical FDM Validation IncludedEvery FDM output is physically built and dimensionally inspected in-house before delivery. You get optimised CAD and sliced files with your parts.
03
IP Protected from First ContactNo portfolio display without written consent. You retain all intellectual property, without any exceptions.
04
Prompt Delivery & Transparent CommunicationWe commit to timelines and we keep them. You will always know where your project stands, from first quote to final delivery.
05
Technical Range Without Trade-offsOne partner, eight engineering materials in-house. We advise on process selection across FDM, SLS, and SLA including when to use something we don't run ourselves.

Industries We Serve

Our clients span technical and creative sectors. What connects them is a need for precision, short lead times, and geometry that conventional manufacturing cannot produce economically.
