Introduction to 3D Printing and Additive Manufacturing
Introduction to 3D Printing and Additive Manufacturing with 3Dresyns® materials.
This page provides a structured entry point into additive manufacturing, focusing on how technologies, materials and manufacturing routes interact in real industrial workflows.
This is not only a technology overview. It is a system-level introduction linking materials, process control and manufacturing architecture.
Start from the concept of additive manufacturing, then move to technologies and finally to manufacturing routes. For real implementation, continue to the Engineering System, Resources or IFU sections.
What is additive manufacturing?
Digital-to-physical manufacturing
Additive manufacturing (AM) converts digital geometry into physical parts by controlled material addition, layer-by-layer, voxel-by-voxel or through volumetric or jetting strategies.
Unlike subtractive or formative processes, AM enables direct translation of geometry complexity into manufacturable structures.
AM as a system, not a printer
Final performance is not defined by the printer alone. It emerges from the interaction between:
- material formulation and chemistry
- printing technology and energy delivery
- geometry and design constraints
- post-processing and curing
- validation and application conditions
This is why 3Dresyns® structures additive manufacturing as an engineering system rather than a set of isolated machines or materials.
Main additive manufacturing technologies
Photopolymer-based systems
Photopolymer AM uses controlled light exposure to structure liquid resins into solid parts.
- SLA: laser-based curing
- DLP: projected layer exposure
- LCD / MSLA: masked LED exposure
- Inkjet: drop deposition + curing
- 2PP: micro/nano-scale fabrication
- VAM: volumetric light-based shaping
Powder-based and hybrid routes
Powder-based AM and hybrid systems combine shaping with thermal processing, sintering or binder-based consolidation.
- SLS and powder sintering
- Cold metal / ceramic fusion
- binder-assisted shaping
Direct vs indirect additive manufacturing
Direct AM
The printed object is the final or near-final part.
Best suited for rapid iteration, prototyping, functional resin parts and selected direct ceramic or metal-loaded systems.
Indirect AM
The printed object is an intermediate: mold, pattern, sacrificial structure or tooling element.
The final part is produced through casting, injection, debinding, sintering or other downstream processes.
Why this distinction matters
In many industrial cases, indirect AM provides better final material performance, higher density, improved scalability and more robust manufacturing routes.
Applications and material systems
Application-driven additive manufacturing
3Dresyns® materials support workflows across engineering, dental, medical, casting, mold-making, microfabrication and advanced manufacturing.
Material systems, not generic resins
Material selection must consider process behaviour, curing kinetics, mechanical response and downstream workflow compatibility.
Nominal labels such as ABS-like or PP-like are insufficient to predict real performance.
3Dresyns® approach
Engineering-driven additive manufacturing
3Dresyns® structures AM through:
- material system design
- engineering selection frameworks
- process control and calibration
- validation and mechanical screening
- application-specific workflows
