How does SLS 3D printing work?
Official overview of the Fuse process. A process example; it does not establish compatibility for other powders or machines.
THE MATERIALS KNOWLEDGE HUB
Practical guides to 3D printing materials
Compare material properties, understand processing requirements and prepare a purchasing specification.
TECHNICAL & PURCHASING GUIDES
Find the question you came with.
Each guide separates general principles, illustrative examples and the conditions that still need exact-grade confirmation.
20 guides
How to choose filament for a working part
Translate the part’s job into a material shortlist, then check the grade, printer and trial process.
Read the guideSpecify printing powder beyond the material name
Build a clear RFQ around process, particle distribution, chemistry, condition and batch evidence.
Read the guideChoose resin as a complete print-and-cure system
Understand the supplied formulation, exposure system, cleaning route and finished-part requirements.
Read the guideTDS, SDS, COA and CoC: use the right document
Separate grade information, safe handling, batch test results and a declaration of conformity.
Read the guideCheck printer compatibility in layers
Work through physical fit, hardware capability, process settings and application validation.
Read the guidePrepare a private-label material brief
Separate the material specification, brand presentation, approval sample and repeat-order requirements.
Read the guideStrength, stiffness and toughness describe different jobs
Read the property that matches the failure mode instead of choosing the largest number on a datasheet.
Read the guideHDT, glass transition and service temperature
Understand what a heat number measures and the questions needed for a loaded, real-world part.
Read the guideDrying and storage: control moisture before tuning
Separate active drying, dry storage and a controlled feed path, and keep a record of what changed.
Read the guideCarbon- and glass-filled filament: what changes?
Compare reinforcement benefits with nozzle wear, moisture control and the actual printed structure.
Read the guideFilament diameter, ovality and repeatable flow
Understand what a diameter tolerance controls and which other variables can change extrusion.
Read the guideSLS refresh rate and reused powder, explained
Understand fresh-powder mass fraction, batch history and the limits of a simple blend calculation.
Read the guideWhat makes a metal-powder batch acceptable?
Build acceptance around the agreed chemistry, distribution, measurement methods and traceable supply condition.
Read the guideWhat “water washable” tells you about a resin
It identifies a cleaning route. Review final properties, post-cure instructions and contaminated wash handling separately.
Read the guideQualify castable resin through to the finished casting
Include geometry, cleaning, investment and burnout when comparing a castable printing material.
Read the guideBiobased, recycled and compostable: ask for specifics
Understand feedstock origin, recycled content and end-of-life conditions before making a material claim.
Read the guideTurn a sample print into a useful approval record
Set a small, repeatable trial that checks the part requirement and creates a reference for the next batch.
Read the guideCompare cost per accepted part, not only price per kilogram
Build a transparent estimate that includes material used, machine time, finishing and yield.
Read the guidePackaging, batch labels and repeat-order control
Specify what arrives, what identifies it and which approved version the next order must reproduce.
Read the guideCeramic and bound-metal feedstocks need a downstream process
Understand green parts, binder removal, sintering and dimensional approval before buying a feedstock.
Read the guideNo matching guide. Try a material family, property or purchasing term, or clear the filters.
WATCH THE WORKFLOW
See the process on real equipment.
Official manufacturer training. These videos illustrate the named systems; use the instructions for your own equipment and material.
SLS powder recovery and post-processing
Fuse 1 and Sift workflow. Recovery and reuse must follow the actual material and equipment instructions.
Resin washing, drying and post-curing
Form 4 / Form 4L post-processing example. Use your grade-specific cleaning and cure schedule.
