Glossary — 3D Printing, UAV & Advanced Manufacturing Terms
Plain-language definitions for industrial 3D printing, UAV, drone and additive-manufacturing terms used in India. Compiled by Autoabode’s engineering team for defence, aerospace, medical and R&D clients.
3D Printing
- FDM (Fused Deposition Modeling)
- FDM is an additive manufacturing process that extrudes a thermoplastic filament through a heated nozzle to build a part layer by layer. It is the most widely used industrial 3D printing technology for functional prototypes, jigs, fixtures and end-use parts in materials like ABS, PC, PEEK and carbon-fibre-reinforced nylon. Autoabode manufactures the Duper Series of industrial CoreXY FDM 3D printers in India.
- SLS (Selective Laser Sintering)
- SLS is a powder-bed additive manufacturing process that fuses polymer powder (typically Nylon 12, Nylon 11, PA12-GF or TPU) with a CO₂ or fibre laser to build dense, isotropic parts without the need for support structures. SLS is the preferred technology for low-volume end-use production of drone frames, aerospace brackets and snap-fit assemblies. Autoabode manufactures SinterX Pro, India's first domestically built industrial SLS 3D printer.
- SLA (Stereolithography)
- SLA is a vat-photopolymerisation process that cures liquid photopolymer resin layer by layer using a UV laser or DLP projector. SLA produces extremely smooth surface finishes and fine features, making it ideal for dental models, jewellery masters, microfluidics and concept prototypes. Autoabode offers large-format SLA printing services for Indian design and R&D teams.
- DMLS (Direct Metal Laser Sintering)
- DMLS is a metal additive manufacturing process that uses a high-power fibre laser to melt and fuse fine metal powder (titanium, Inconel, aluminium, stainless steel) layer by layer. It is used for aerospace brackets, medical implants, turbomachinery and tooling inserts where part performance justifies the cost.
- PEEK (Polyether Ether Ketone)
- PEEK is a high-performance semi-crystalline thermoplastic with exceptional mechanical strength, chemical resistance and a continuous-use temperature of around 260 °C. It is used as a metal replacement in aerospace, defence and medical implants. PEEK printing requires a fully heated chamber above 140 °C, which the Autoabode Duper Series supports for industrial customers in India.
- Carbon-Fibre Reinforced Nylon (CF-Nylon)
- CF-Nylon is a chopped-carbon-fibre-reinforced polyamide used in industrial FDM printing. It offers up to 2× the stiffness of unfilled nylon at roughly the same density, making it a common choice for UAV airframes, drone arms, end-of-arm tooling and structural jigs.
- Build Volume
- The maximum X × Y × Z dimensions a 3D printer can print in a single job. Autoabode's Duper XL series offers build volumes from 300 × 300 × 400 mm to 600 × 600 × 800 mm, among the largest industrial FDM envelopes available in India.
- Rapid Prototyping
- Rapid prototyping is the practice of using additive manufacturing, CNC machining and laser cutting together to produce functional product prototypes in days rather than weeks. Autoabode operates a full-stack rapid prototyping lab in India combining FDM, SLS, CNC, laser and an embedded engineering team.
- CoreXY Motion System
- CoreXY is a parallel belt-driven motion architecture where two stepper motors work together to move the print head in X and Y. It enables higher print speeds and better dimensional accuracy than traditional Cartesian systems. The Autoabode Duper Series uses a high-speed CoreXY motion system rated for 500 mm/s print speeds.
UAV & Drones
- UAV (Unmanned Aerial Vehicle)
- A UAV is an aircraft that operates without an onboard pilot, flown either autonomously or under remote control. In India, UAVs are used for ISR (intelligence, surveillance, reconnaissance), logistics, survey and agriculture. Autoabode designs and manufactures defence-grade UAV platforms including the BotBit reconnaissance UAV.
- UGV (Unmanned Ground Vehicle)
- A UGV is an unmanned robotic ground platform used for reconnaissance, EOD (explosive ordnance disposal), logistics and counter-drone interception. Autoabode's GroundHawk is an autonomous UGV interceptor developed for Indian homeland security missions.
- VTOL (Vertical Take-Off and Landing)
- A VTOL drone takes off and lands vertically like a multirotor but cruises efficiently in fixed-wing mode, combining hover capability with long endurance. The Autoabode VTOL X1 hybrid fixed-wing drone is designed for wide-area mapping and surveillance missions in India.
- Counter-UAS / C-UAS
- Counter-UAS (or C-UAS) is the detection, tracking, identification and neutralisation of hostile unmanned aircraft using RF, radar, EO/IR and kinetic or electronic countermeasures. Autoabode's SkyShield is an Indian counter-drone system combining RF and optical detection with both soft-kill and hard-kill neutralisation.
- FPV (First Person View)
- FPV is a drone flying mode where the pilot sees a live camera feed from the drone through goggles or a ground-station monitor. FPV platforms are used for racing, inspection and precision payload delivery. Autoabode offers a range of FPV quadcopters and multi-payload FPV platforms.
- EO/IR Gimbal
- An electro-optical / infrared (EO/IR) gimbal is a stabilised camera payload combining a daylight EO camera with a thermal IR sensor, used for ISR and target tracking on tactical UAVs.
- RTK GNSS
- Real-Time Kinematic GNSS is a satellite-positioning technique that provides centimetre-level accuracy by applying phase corrections from a base station or network in real time. Survey-grade drones use RTK for 5 mm horizontal accuracy.
- PPK GNSS
- Post-Processed Kinematic GNSS logs raw GNSS observations onboard the drone and the base station, then applies corrections in post-flight to produce centimetre-accurate positions. PPK is preferred for long-range missions where a real-time radio link to a base is not practical.
- BVLOS (Beyond Visual Line of Sight)
- BVLOS drone operations are flown beyond the direct eyesight of the remote pilot, enabling long-range survey, logistics and inspection. In India, BVLOS operations require specific DGCA authorisation under the Drone Rules 2021.
- DGCA (Directorate General of Civil Aviation)
- The DGCA is the regulator for civil aviation in India and administers the Drone Rules 2021, which govern registration, pilot licensing, airspace zones and BVLOS approvals for all civil drone operations.
Defence & Institutions
- DRDO (Defence Research and Development Organisation)
- DRDO is the R&D wing of the Indian Ministry of Defence, headquartered in New Delhi, responsible for developing defence technologies ranging from missiles and radar to unmanned systems. Autoabode supplies 3D printed defence components and works with DRDO laboratories on additive manufacturing and UAV projects.

- iDEX is a Ministry of Defence framework that funds Indian start-ups and MSMEs to develop defence technologies for the armed forces, including UAVs, counter-drone systems and additive manufacturing.
Advanced Manufacturing
- Additive Manufacturing (AM)
- Additive manufacturing is the umbrella term for processes that build parts by adding material layer by layer, as distinct from subtractive processes like CNC machining. It includes FDM, SLS, SLA, DMLS and binder jetting.
- Reverse Engineering
- Reverse engineering is the process of 3D scanning an existing physical part, generating a CAD model from the scan data and reproducing or improving the part. It is critical for legacy spare parts, obsolete defence components and regulatory documentation.
- Topology Optimisation
- Topology optimisation is a computational design technique that removes material from regions that carry low stress, producing organic, lightweight geometries best manufactured with SLS or DMLS. It is widely used to reduce UAV airframe weight.
- Digital Twin
- A digital twin is a live digital model of a physical asset, updated from sensor data, used for monitoring, simulation and predictive maintenance of manufacturing cells and UAV fleets.
- On-Demand Manufacturing
- On-demand manufacturing produces parts only when ordered, eliminating large inventories. Additive manufacturing enables on-demand production of defence spare parts, tooling and low-volume end-use components in India.
