WHY CarbonX PP+CF15
CF Stiffness. Chemical Resistance of PP. Lightest Density in the Line.
CarbonX™ PP+CF15 is 3DXTech’s 15% carbon fiber reinforced polypropylene — delivering 6,150 MPa tensile modulus in a chemical-resistant polyolefin matrix at just 1.1 g/cc. PP resists acids, bases, alcohols, and organic solvents that degrade ABS, PETG, and PC. The only CF-PP option with a verified TDS. Hardened steel nozzle ≥0.4mm required. Made in Grand Rapids, Michigan.
6,150 MPa Tensile Modulus
15% chopped carbon fiber reinforcement raises tensile modulus to 6,150 MPa — the highest in the CarbonX polyolefin class. Carbon fiber alignment during FFF extrusion maximizes in-layer stiffness for structural brackets, chemical fixtures, and fluid-contact components.
Chemical Resistance of PP
Polypropylene resists a wide range of chemicals including dilute acids, bases, alcohols, and organic solvents. PP+CF15 brings this chemical inertness to CF-stiffened structural parts — enabling fittings, brackets, and fixtures in contact with process fluids where PETG or ABS would degrade.
Lowest Density in CarbonX Line
At 1.1 g/cc, PP+CF15 is the lightest composite in the CarbonX family — lighter than PETG+CF (1.34 g/cc), ABS+CF (1.2 g/cc), and PC+CF (1.3 g/cc). Maximum stiffness-to-weight for aerospace, automotive, and lab applications where mass is a constraint.
Verified TDS — Only CF-PP with Data
3DXTech publishes a full Technical Data Sheet for CarbonX PP+CF15 with ISO-standard mechanical test results. The only CF-reinforced PP filament on the market with a verified, independently testable TDS — eliminating the guesswork of commodity generic PP composites.
PRINTING WITH CarbonX PP+CF15
PP+CF15 Is Powerful — But PP Demands Attention to Bed Adhesion
CarbonX PP+CF15 delivers CF-grade stiffness in a chemical-resistant polyolefin matrix. PP is a semi-crystalline polymer with excellent chemical resistance but notoriously low bed adhesion and tendency to warp — a PP-specific build surface (PP sheet, Magigoo Pro PP, or PP tape) is required for reliable results. Enclosure strongly recommended to manage dimensional stability. Hardened steel nozzle ≥0.4mm mandatory.
- Extruder Temp 265°C — single target from TDS; all-metal hot end required for temperatures above 260°C
- Bed Temp 85°C — PP-specific build surface required (PP sheet, Magigoo Pro PP, or PP-compatible adhesive)
- Bed Adhesion PP DOES NOT ADHERE to standard PEI, glass, or BuildTak. Use PP print sheet, Magigoo Pro PP, or Dimafix PP. This is the most critical print requirement for PP+CF15.
- Enclosure Recommended — PP is semi-crystalline and prone to warping on larger parts; enclosure significantly improves dimensional stability and layer adhesion
- Nozzle Hardened steel ≥0.4mm MANDATORY — carbon fiber is abrasive and will wear brass nozzles rapidly
- Layer Height 0.25mm or higher recommended for consistent CF fiber distribution and layer adhesion
- Drying 65°C / 4 hours before printing — PP absorbs minimal moisture vs. PETG/PA, but drying before printing ensures best results
THERMAL DATA
124°C HDT — Excellent Thermal Performance for a Polyolefin
Four thermal milestones defining CarbonX™ PP+CF15’s operating envelope — verified against 3DXTech CarbonX PP+CF15 TDS. PP is semi-crystalline (no Tg) — thermal performance characterized by melting point and HDT.
Heat deflection temperature under load — exceptional for a polyolefin. CF reinforcement dramatically raises PP’s HDT above unfilled PP (~100°C). Suitable for continuous service up to ~110°C under moderate load in chemical environments where PC or PETG would be chemically attacked.
PP is semi-crystalline — no glass transition temperature (Tg). Parts maintain dimensional integrity below the HDT (124°C); above melting point (~160°C) the crystalline structure dissolves. Thermal performance is characterized by HDT rather than Tg for semi-crystalline polymers.
Single target from TDS. All-metal hot end required — PTFE-lined hot ends are rated to ~240°C and not suitable. Higher processing temperature vs. PETG+CF (230–260°C) but lower than PC+CF (280–310°C). Enclosure recommended to prevent warping.
PP absorbs significantly less moisture than PETG or PA, but drying before printing is still recommended. 65°C for 4 hours eliminates any residual moisture contamination and helps ensure consistent extrusion quality session-to-session.
APPLICATIONS
Chemical-Resistant Brackets. Fluid-Contact Fixtures. Lab Equipment.
CarbonX™ PP+CF15 combines the chemical resistance of polypropylene with carbon fiber stiffness — enabling structural parts in contact with acids, bases, alcohols, and solvents that would degrade ABS, PETG, or PC. 6,150 MPa tensile modulus and 124°C HDT extend the performance envelope for polyolefin composites.
Chemical-Resistant Structural Brackets
Brackets and mounts for environments with chemical exposure — labs, chemical processing, water treatment. PP resists dilute acids, alkalis, alcohols, and organic solvents. CF reinforcement provides 6,150 MPa stiffness where unfilled PP would deflect under load.
Fluid-Contact Fittings & Flow Components
Fittings, manifolds, and flow components in contact with weak acids, cleaning agents, alcohols, and aqueous solutions. PP is widely used in industrial fluid handling for its chemical inertness. PP+CF15 adds structural rigidity for pressure-bearing or dimensionally critical components.
Lab Equipment & Sample Fixtures
Sample holders, fixture plates, and lab consumables requiring chemical inertness. PP is standard in laboratory plasticware for its compatibility with most reagents. CF reinforcement makes PP+CF15 a structural alternative to machined PP for custom lab fixtures at prototype volumes.
Hardened steel nozzle ≥0.4mm mandatory. PP-specific bed surface required. Enclosure strongly recommended. Consult 3DXTech CarbonX PP+CF15 TDS for complete mechanical data, chemical resistance tables, and test methodology.

WHERE IT WORKS
Where Chemical Resistance + CF Stiffness Is the Only Answer
When you need structural stiffness beyond unfilled PP and chemical resistance that rules out PETG, ABS, or PC — CarbonX PP+CF15 delivers 6,150 MPa modulus in a polyolefin matrix that withstands dilute acids, bases, alcohols, and organic solvents.
Chemical Process Industry Fixtures
Brackets, clamps, and fixtures in wet chemical environments. PP’s resistance to dilute acids, alkalis, and cleaning agents makes PP+CF15 the only CF composite suitable for environments where PETG, ABS, and PC would be chemically attacked. 6,150 MPa provides structural rigidity under load.
Automotive Fuel System Components
Fuel-contact prototypes, brackets, and clips where hydrocarbon resistance is required. PP is widely used in automotive fuel systems for its resistance to petrol and lubricants. CF reinforcement adds the stiffness needed for structural mounting applications.
Lab Equipment & Analytical Fixtures
Custom laboratory fixtures, sample holders, and flow cell components. PP is the standard lab plastic for reagent compatibility — PP+CF15 extends that chemical inertness into stiff structural parts that machined PP rods or injection-molded PP components cannot achieve at prototype volumes.
Fluid-Contact Fittings & Manifolds
Fittings, tees, and manifolds for aqueous process streams, cleaning agent lines, and solvent-containing flows. PP is the preferred polymer for industrial piping in chemical plants — PP+CF15 brings that chemistry to custom-geometry FFF-printed flow components.
Lightweight Structural Brackets (Weight-Critical)
At 1.1 g/cc, PP+CF15 is the lightest CF composite in the CarbonX line. For weight-critical aerospace prototypes, drone components, or UAV-mounted equipment brackets where chemical resistance is also required — no other FFF CF composite offers this combination.
Water Treatment & Wastewater Fixtures
Structural components for water treatment equipment, sampling fixtures, and sensor mounts in aqueous environments. PP resists chlorinated water, salt solutions, and pH-variable streams. CF reinforcement maintains dimensional stability in continuously wet environments.
MATERIAL CARE & PRINT TIPS
Bed Adhesion Is Everything With PP. Prepare Your Surface First.
PP is a semi-crystalline polyolefin with very low surface energy — the most common print failure is first-layer lift due to inadequate bed adhesion. A PP-compatible bed surface is non-negotiable. Follow this protocol for reliable PP+CF15 results.
Use a PP-Compatible Bed Surface
Standard PEI, glass, and BuildTak are incompatible with PP. Use a PP print sheet, Magigoo Pro PP adhesive, Dimafix PP, or PP packing tape on your build plate. This single step is the difference between successful PP+CF15 prints and recurring first-layer failures.
Print With Enclosure
Enclose your printer if possible. PP is semi-crystalline and contracts as it cools — draft-free, elevated ambient temperature inside the enclosure reduces warping and layer delamination on larger parts. Even a cardboard enclosure improves results.
Dry Before Printing
65°C for 4 hours before every print session. PP absorbs less moisture than PETG or PA, but drying is still recommended for consistent extrusion. Store unused filament in an airtight bag with desiccant between print sessions.
Store Sealed With Desiccant
Return unused filament to an airtight bag or container with fresh desiccant immediately after printing. Long-term storage in original sealed packaging with desiccant is acceptable. PP has better moisture stability than hygroscopic filaments but sealed storage is best practice.
HOW IT COMPARES
CarbonX™ PP+CF15 vs. Commonly Evaluated Alternatives
Buyers evaluating CarbonX PP+CF15 typically compare against CarbonX PETG+CF (easier printing, similar stiffness range), CarbonX ABS+CF (higher Tg, better adhesion), and generic unfilled PP (no stiffness, no TDS). PP+CF15 uniquely combines CF stiffness, PP chemical resistance, and the lightest density in the CarbonX line.

FREQUENTLY ASKED
CarbonX™ PP+CF15 — Buyer & Engineer Questions Answered
What is CarbonX™ PP+CF15?
CarbonX™ PP+CF15 is 3DXTech’s 15% carbon fiber reinforced polypropylene filament. Available in Black (1.75mm, 750g at $78), it delivers 6,150 MPa tensile modulus and 78 MPa tensile strength in a chemical-resistant polyolefin matrix at 1.1 g/cc density — the lightest composite in the CarbonX line. Hardened steel nozzle ≥0.4mm mandatory. PP-specific bed surface required. Made in Grand Rapids, Michigan.
What mechanical properties does CarbonX PP+CF15 deliver?
CarbonX PP+CF15 delivers 78 MPa tensile strength, 6,150 MPa tensile modulus, 68 MPa flexural strength, and 6,100 MPa flexural modulus at 1.5% elongation. HDT is 124°C at 0.45 MPa (ISO 75). Melting point is ~160°C (semi-crystalline — no Tg). Density is 1.1 g/cc — the lowest in the CarbonX line. All values per ISO 527 / ISO 178 on 1.75mm black filament.
Why is PP so difficult to print and how do I solve it?
PP is a semi-crystalline polyolefin with very low surface energy — it simply does not adhere to standard PEI, glass, or BuildTak build surfaces. The solution is a PP-compatible bed surface: a PP print sheet, Magigoo Pro PP adhesive, Dimafix PP, or PP packing tape applied to your build plate. Enclosure is also strongly recommended to prevent warping as PP contracts during cooling. These two steps resolve the majority of PP print failures.
What is the chemical resistance of CarbonX PP+CF15?
Polypropylene resists a wide range of chemicals including dilute mineral acids (hydrochloric, sulfuric, phosphoric at low concentrations), alkalis, alcohols (methanol, ethanol, isopropanol), and many organic solvents. PP is incompatible with concentrated oxidizing acids and aromatic/chlorinated hydrocarbons. PP+CF15 inherits the full PP chemical resistance profile — consult the 3DXTech TDS and a PP chemical resistance chart for specific reagents before use.
What print settings does CarbonX PP+CF15 require?
Extruder: 265°C (all-metal hot end required). Bed: 85°C with PP-specific surface (PP sheet, Magigoo Pro PP, or PP tape — standard PEI and glass will not work). Enclosure: recommended. Nozzle: hardened steel ≥0.4mm. Layer height: 0.25mm or higher. Drying: 65°C for 4 hours before every print session. Higher print temp (265°C) requires an all-metal hot end — PTFE-lined hot ends are not rated for this temperature.
Does PP have a glass transition temperature (Tg)?
No — polypropylene is semi-crystalline, not amorphous, so it does not have a glass transition temperature. Thermal performance for PP is characterized by melting point (~160°C) and heat deflection temperature (HDT). CarbonX PP+CF15’s HDT is 124°C at 0.45 MPa — excellent for a polyolefin and significantly above unfilled PP (~100°C), thanks to CF reinforcement improving dimensional stability under load.
How does CarbonX PP+CF15 compare to CarbonX PETG+CF?
PP+CF15 has higher tensile modulus (6,150 MPa vs. 5,230 MPa), higher HDT (124°C vs. 77°C), lower density (1.1 g/cc vs. 1.34 g/cc), and superior chemical resistance. PETG+CF is significantly easier to print — no PP-specific bed surface required, no enclosure needed, lower print temp (230–260°C vs. 265°C), and lower cost ($50 vs. $78). Choose PP+CF15 when chemical resistance or minimum weight are the primary requirements; choose PETG+CF when printability and accessibility matter most.
Where is CarbonX PP+CF15 made?
CarbonX™ PP+CF15 is manufactured in-house by 3DXTech in Grand Rapids, Michigan, USA under ISO 9001:2015 certification. It is the only CF-PP filament on the market with a publicly verifiable Technical Data Sheet with ISO-standard mechanical test results.
