High Performance Powders for Selective Laser Sintering SLS printing of high quality functional polymers

Choose your SLS polymer family

Use the routes below to navigate the collection by polymer family and application logic.

• High-performance SLS polymer powders for functional polymer printing.
• Stable powder processing behaviour and repeatable sintering outcomes.
• Coverage from rigid engineering polyamides to flexible PEBA, bioresorbable PCL and multiple polyolefin routes.
• Suitable for engineering prototyping, functional parts and production-oriented polymer workflows.

Typical use scenarios across the collection

This collection is relevant for teams selecting SLS powders according to end-use behaviour, required polymer family and workflow priorities.

• Functional SLS parts: parts requiring usable mechanical performance beyond visual prototyping.
• Durable polymer components: engineering-grade parts where wear, toughness, flexibility or polymer-specific behaviour matters.
• Engineering prototypes: prototypes intended to reflect functional behaviour more closely than generic demonstration parts.
• Short-run production: manufacturing-oriented workflows where repeatability and powder handling stability are important.
• End-use capable parts: depending on polymer family, printer setup and qualified process window.

How to choose the right SLS powder

Select the most suitable material according to polymer family, required part behaviour and preferred powder profile.

• Need classic engineering polyamide performance → Nylon 11 or Nylon 12
• Need flexible or elastomeric behaviour → TPE / PEBA
• Need lightweight polypropylene behaviour → PP
• Need bio-based PLA route → PLA
• Need a biodegradable, bioresorbable route with the lowest melting temperature for cold low-energy printing → PCL
• Need polyethylene-specific wear, low-friction or density-related behaviour → UHMWPE, LDPE or HDPE

• Prioritise ultra-fine / higher-resolution powder routes → consider PLA20-80, LDPE15-25 or other fine-profile powders
• Prioritise ultra-low temperature, cold low-energy printing → consider PCL40-100 (lowest melting powder in the range)
• Prioritise engineering familiarity and classic SLS polymer logic → consider PA11, PA12 or PP routes

Decision tree summary

Use this simplified engineering logic before detailed process validation.

• Need rigid engineering polymer behaviour → Nylon 11 / Nylon 12
• Need flexible or elastomeric response → TPE / PEBA
• Need lighter polyolefin route → PP
• Need bio-based thermoplastic route → PLA
• Need biodegradable, bioresorbable behaviour at ultra-low melting temperature → PCL
• Need polyethylene-type wear, low friction or compliance behaviour → UHMWPE / LDPE / HDPE

Then validate the final powder choice under the intended printer, powder refresh strategy, energy density window and post-processing route.

Nylon engineering powders

For high-resolution SLS printing of functional polymer parts based on polyamide families.

Thermoplastic elastomer PEBA powder

For SLS workflows requiring a more flexible or elastomeric material route.

PP powder for lightweight functional parts

For users evaluating polypropylene-based SLS parts with a narrower medium particle profile.

Fine-profile PLA powder

For teams interested in a PLA-based SLS powder route with fine and narrow particle size distribution.

Ultra-low melting bioresorbable PCL powder

For biomedical, tissue-engineering and low-temperature prototyping workflows. PCL is the lowest-melting functional powder in the range (around 60 ºC), enabling cold, low-energy SLS printing of flexible, biodegradable and bioresorbable parts on printers with minimal or no bed heating.

UHMWPE, LDPE and HDPE powder options

For polyethylene-based SLS workflows where wear behaviour, low friction, compliance or density-related behaviour is relevant.

A broad SLS polymer portfolio rather than a single-material offer

The collection covers multiple polymer families so users can compare engineering polyamides, flexible elastomeric powders, bioresorbable PCL and several polyolefin routes inside one SLS platform.

• NYLON11 15-85 and NYLON12 30-50 define the polyamide side of the collection for demanding functional and engineering SLS parts.
• TPE15-150 extends the portfolio toward flexible or elastomeric PEBA-based behaviour.
• PP50-80 adds a polypropylene route for functional polymer parts.
• PLA20-80 introduces a PLA-based option with a fine powder profile.
• PCL40-100 adds a biodegradable, bioresorbable route with the lowest melting temperature in the range for cold, low-energy printing of flexible biomedical parts.
• UHMWPE25-55, LDPE15-25 and HDPE35-65 broaden the offer into multiple polyethylene routes with different behavioural profiles.

The right SLS powder depends on polymer family, target part behaviour and powder profile

Choose polyamides for classic engineering routes, elastomeric powders for more flexible parts, PCL for biodegradable and bioresorbable parts at ultra-low melting temperature, and PP, PLA or polyethylene families when density, compliance, wear behaviour, low friction or polymer-specific performance are more relevant to the final application.

Final selection should always be validated under the intended SLS machine, thermal window, powder refresh strategy and application requirements.
