FREQUENTLY ASKED QUESTIONS
COMPOSITE MATERIALS
Markforged composite parts are primarily composed of base plastic materials. These base materials can be reinforced with continuous fibers through a process called CFR – Continuous Fiber Reinforcement. Composite Materials are available for both the Desktop and Industrial Series 3D printers.
What are the dimensions of the
test specimens used for the base material tests?
Tensile: ASTM D638 type IV beams ; Flexural: 3-PT Bending 4.5 in (L) x 0.4
in (W) x 0.12 in (H). Plastic specimens are printed with full infill.
Do Markforged composite materials
need to be stored in a dry box?
The plastic base materials do need to be stored in a dry box while the
fibers do not. Each plastic package will come with desiccant packs to
ensure that material stays dry.
What is the shelf life of
Markforged composite 3D printing materials?
Unopened plastics and fibers have a minimum shelf life of two years from
the date of manufacture when stored in their original package at 55°-90°
F. Unsealed plastic (stored in a dry box) and fiber spools can be stored
for up to one year.
What are the test specimen details
for fibers?
Fiber specimens are designed to maximize mechanical performance and are
printed with unidirectional fiber without walls. Tensile test specimens:
9.8 in (L) x 0.5 in (H) x 0.048 in (W) (Carbon Fiber composites), 9.8 in
(L) x 0.5 in (H) x 0.08 in (W) (Fiberglass and Kevlar® composites).
Compressive test specimens: 5.5 in (L) x 0.5 in (H) x 0.085 in (W) (Carbon
Fiber composites), 5.5 in (L) x 0.5 in (H) x 0.12 in (W) (Kevlar® and
Fiberglass composites). Flexural test specimens: 3-pt. Bending, 4.5 in (L)
x 0.4 in (W) x 0.12 in (H).
What are the details of the UL-94
test for Onyx FR?
Onyx FR is Blue Card certified down to a thickness of 3mm.
What is special about the
aerospace-grade materials, Onyx FR-A and Carbon Fiber FR-A?
Both Onyx FR-A and Carbon Fiber FR-A are designed for the requirements of
aerospace and have lot-level traceability qualified under 14 CFR 25.853.
Parts printed with these materials are FST compliant for aircraft
interiors (flame, smoke, toxicity). Onyx FR-A and Carbon Fiber FR-A are
also undergoing qualification through the NCAMP process. Every spool comes
with a CoC (Certificate of Conformance) and CoA (Certificate of Analysis).
What are the test conditions for
heat deflection temperatures?
Heat-deflection temperature was tested at 0.45 MPa, 66 psi (ASTM D648-07
Method B)
METAL MATERIALS
Markforged metal materials contain bound metal powder filaments that utilize a wax binding material to enable the extrusion of material through a nozzle. This process utilizes the same Fused Filament Fabrication (FFF) technique found in Markforged composite systems. These materials are compatible with the Metal X printing system.
How do Markforged metal materials
compare to traditional materials such as wrought, or metal injection
molded materials?
Markforged parts typically have stronger mechanical properties than metal
injection molded versions of the same material, but slightly lower
mechanical properties compared to wrought materials used in subtractive
manufacturing methods. See the 17-4 mechanical datasheet for more details.
What is the raw surface finish of a
Metal X part like? Can this finish be improved?
The raw surface finish on a Metal X part depends on the part geometry
itself. Vertical walls and parts printed directly on the print sheet tend
to have the best surface finish, while dome shapes (susceptible to
stepping), top surfaces, and support surfaces tend to have worse surface
finishes. Parts can be wet sanded in the green state and polished after
sintering to provide a mirror finish. Machining post-sinter can also
improve the surface finish.
What print settings were used for
the Markforged metal mechanical properties table?
Parts were printed as fully dense with 100% infill.
