ABS Enhanced (Production-Grade ABS) for FDM

Material Profile: ABS Enhanced (Production-Grade ABS) for FDM

FDM Engineering Material Technical Report Series

Compiled from manufacturer technical datasheets and peer-reviewed literature

Abstract—ABS Enhanced (Stratasys ABS-M30 and equivalents) is a re-engineered ABS formulation delivering 25–70% higher tensile strength in Z direction  than conventional ABS, with improved interlayer bonding and elongation. It is the workhorse FDM material for functional prototypes, jigs, fixtures, and low-volume production parts.

Index Terms—additive manufacturing, FDM, ABS, ABS-M30, production-grade thermoplastic.

I.  MATERIAL IDENTIFICATION

This section establishes the canonical names and commercial designations under which the material is supplied.

A.  Designation

Trade name: ABS-M30™ (Stratasys, the canonical 'Enhanced ABS' grade). Equivalents: production-grade or industrial ABS from competing suppliers.

B.  Full Chemical Name

Acrylonitrile-Butadiene-Styrene terpolymer with optimised molecular weight distribution and tailored rubber phase morphology to enhance interlayer adhesion and impact strength.

C.  Aliases and Alternative Designations

II.  COMPOSITION AND MOLECULAR STRUCTURE

A.  Empirical Chemical Formula

Idealised ABS terpolymer: [(C₃H₃N)ₐ-(C₄H₆)ᵦ-(C₈H₈)ᵧ]ₙ with composition tuned for FDM (typically 20–25% acrylonitrile, 15–25% butadiene, 50–60% styrene by mass).

III.  MECHANICAL PROPERTIES — XZ PRINT DIRECTION

In the XZ orientation the tensile load is applied parallel to the deposited rasters; for fibre-reinforced grades this is the strongest orientation because the fibres align preferentially along the extrusion direction.

 MECHANICAL PROPERTIES — XZ ORIENTATION (ABS ENHANCED (ABS-M30))

IV.  MECHANICAL PROPERTIES — ZX PRINT DIRECTION

In the ZX orientation the tensile load is applied perpendicular to the print layers, so failure occurs through inter-layer (Z) bonds. Properties are markedly lower than in XZ — this anisotropy is intrinsic to FDM.

TABLE III
 MECHANICAL PROPERTIES — ZX ORIENTATION (ABS ENHANCED (ABS-M30))

ABS-M30 anisotropy ratio (XZ:ZX UTS ≈ 1.3:1) is the lowest of the standard ABS grades — Stratasys's Enhanced formulation specifically optimises interlayer adhesion. This makes it suitable for parts whose principal load is not predictable.

V.  RECOMMENDED PRINT PARAMETERS

Values summarised below give consensus operating windows from public datasheets. Specific suppliers may differ within ±10 °C; the supplier datasheet always supersedes this table.

VI.  GLASS TRANSITION TEMPERATURE (TG)

Reported / typical Tg: ≈ 108 °C.

ABS retains substantial stiffness up to ~80 °C continuous service. Annealing is generally not performed for ABS — the polymer is fully amorphous and offers no crystallinity gains, but acetone-vapour smoothing is widely used to reduce surface roughness and slightly improve interlayer adhesion.

VII.  HEAT DEFLECTION TEMPERATURE (HDT)

Heat deflection temperature is the temperature at which a standard bar deflects 0.25 mm under a specified flexural load (ASTM D648 / ISO 75).

VIII.  DISTINGUISHING CHARACTERISTICS AND STANDARDS

A.  Enhanced strength versus standard ABS

Stratasys reports 25–70% higher tensile strength versus generic ABS — achieved by tighter molecular weight distribution and optimised rubber-phase domain size. Layer adhesion (XZ:ZX strength ratio) is also markedly improved.

B.  Easy post-processing

ABS dissolves in acetone, allowing acetone-vapour smoothing for cosmetic finishes. Parts can be glued with cyanoacrylate, painted with most plastic-compatible paints, and threaded with helicoils.

C.  Soluble support compatibility

Compatible with Stratasys SR-30 / SR-35 soluble support material, allowing complex internal geometries that would be unprintable with break-away supports.

D.  Limitations

Not flame-retardant (HB rating only); not UV stable (yellowing on prolonged outdoor exposure); HDT limits service to ~80 °C; chemical attack by ketones, esters, halogenated solvents.

IX.  REPRESENTATIVE APPLICATIONS

ABS Enhanced (ABS-M30) is typically deployed in the following applications:

1)  Functional prototypes: End-use part validation before production tooling commitment.

(Source : Stratasys)

2)  Jigs, fixtures, manufacturing aids: Workholding, alignment templates, drill guides.

(Source : Stratasys)

3)  Concept models: Visual / handling models for design review.

4)  Low-volume production parts: Series production where injection moulding is not economically justified.

5)  Consumer product housings: Consumer-electronics enclosures, white-goods replacement parts.
