Appendix A — Master cross-polymer property comparison

Consolidated property tables across the polymer families in this volume. Values are typical FDM-printed-specimen envelopes from manufacturer TDS data, biased toward XY-direction tensile and modulus values where vendors publish them. Specific filament brands and batches will vary within each polymer's range by 10–25%. Cross-reference the per-polymer chapter for engineering decisions.

Table A.1 — Thermal envelope across the polymer families covered in this volume. Continuous service temperature is engineering best practice (T_g minus 20–30 °C for amorphous; T_m minus 60 °C for semi-crystalline) — not the absolute upper limit, which is closer to T_g or HDT. Use this column for service-life calculations; use HDT for short-duration thermal events. (a) PETG is an amorphous copolyester with no true crystalline melting point; it is processed across a melt/processing range of roughly 230–250 °C rather than at a defined T_m. (b) The PEKK row is the amorphous grade (PEKK-A); semi-crystalline PEKK runs a higher continuous-service envelope of roughly 220–240 °C, as noted in §19.4. (c) The PPA rows give printable filament-grade values: commercial PPA filaments are printability-modified semi-aromatic copolymers with a melting point near 230–260 °C, well below the 290–320 °C of neat high-temperature PA6T/PA9T resins. PPA-CF HDT is strongly load- and anneal-dependent — roughly 120 °C at 1.80 MPa rising to ~200 °C at 0.45 MPa after annealing — so the filament datasheet should be read with the test basis in mind.

Table A.2 — Mechanical envelope across the polymer families. Reinforced grades (CF, GF) carry the highest stiffness numbers but the lowest elongation and notched impact — the brittle/stiff trade is structural. Elastomer modulus values are reported low because the polymer flexes under test load; tensile strength remains useful as a relative metric even though elongation dominates elastomer applications. (b) PCTG notched-impact figures vary widely with test method (ISO 180 Izod vs ISO 179 Charpy) and print orientation; the ~8–24 kJ/m² range spans vendor TDS values near the low end and independently measured flat-printed specimens near the high end. Treat it as orientation- and method-dependent, not a single allowable.

Table A.3 — Process envelope and hardware tier across the polymer families. The tier column maps to the §4 hardware definitions: Tier 1 baseline desktop, Tier 2 engineering desktop, Tier 3 active-chamber engineering, Tier 4 ultra-high-temperature industrial (beyond prosumer scope). Filament selection outside the hardware's tier capability produces unreliable results. *PEI-CF straddles the Tier 3/Tier 4 boundary: it prints in a Tier 3 active chamber, but its 140–155 °C bed and 350–390 °C nozzle exceed the Tier 3 envelope defined in §4 (bed £_120 °C) and require Tier 4 thermal hardware. Treat it as boundary hardware, not standard Tier 3. (d) PPA drying guidance varies by brand: the upper end (~140 °C, 8–12 h) suits the higher-melting engineering PPAs such as Bambu PPA-CF, while the printability-modified grades such as Siraya Fibreheart PPA specify a milder 80–100 °C for 4–6 h and treat drying as needed only when moisture symptoms appear. Follow the spool's own datasheet rather than a single family schedule._

Appendix B — Example calibrated filament profiles

Bench-measured calibration values for specific filaments, captured on a representative prosumer setup as worked examples of the §23 calibration workflow. These values are measured, not vendor-supplied; they should be treated as starting points for re-calibration on the reader's actual hardware rather than as universal values. Spool-to-spool drift of 5–10% on EM and PA is normal within the same brand and color.

B.1 Reference hardware setup All values below were measured on a single enclosed CoreXY prosumer printer with a 0.4 mm hardened-tip nozzle (PCD-tipped for the CF-loaded and abrasive grades, hardened steel for the unfilled engineering polymers), in an active-chamber configuration capable of 45–55 °C ambient. Per-spool drying was performed to the §3.5 protocol before each calibration. The calibrations reported here used the Califlower Mk2 XY-shrinkage methodology and the 12-sample wall measurement EM method described in §23.4. Where a different nozzle size was used (0.6 mm high-flow), it is noted in the per-profile entry.

Table B.1 — Bench-measured calibration profiles on a 0.4 mm PCD-tipped or hardened-steel nozzle. Bed surface varies by polymer family per §24; the values above assume the bed surface from that chapter's recommendation. The Prusament ASA profile is in progress at compilation; pressure advance and XY shrinkage are pending.

B.3 Calibrated profiles (0.6 mm high-flow nozzle)

Filament	Nozzle (°C)	Bed (°C)	Chamber (°C)	Max vol. (mm3/s)	EM	PA
Overture ASA (0.6 mm HF)	265	95	45	14	tuned	0.025
Polymaker Fiberon PET-GF15 (0.6 mm HF)	290	80	55–60	13	tuned	0.030
Polymaker Fiberon PPS-CF10 (0.6 mm Diamondback)	350	120	55–65	~10	tuned	tuned

Table B.2 — 0.6 mm high-flow profiles where the larger nozzle was used instead of the 0.4 mm default. Overhang fan settings: 40% for PET-GF15 (reduces stringing on the longer-melt high-flow setup); 0% for ASA and PPS-CF (interlayer adhesion sensitive to cooling at this nozzle scale).

B.4 Notes on workflow Pressure advance is best stored per-filament rather than as a single machine-wide value, so the correct compensation travels with the material instead of requiring a manual reset between filaments. Most firmware implementations expose a way to do this: a per-filament start-G-code command (for example, M900 K… on Marlin, M572 D0 S… on RepRapFirmware and Prusa Buddy firmware, or the SET_PRESSURE_ADVANCE macro on Klipper), or a per-filament field in the slicer profile on printers that manage the value in firmware. The profiles above were captured with the value in the filament start G-code; the reader should use whichever mechanism their own firmware and slicer provide. Skew correction, where the frame is measured out of square, is applied either in firmware or as a G-code post-processing step and validated against a printed skew calibration model; the residual after correction on the reference setup was below 0.02°. Z-shrinkage compensation was intentionally skipped on most profiles where Z-axis dimensional precision was already within the engineering tolerance for the intended application; it is worth measuring only where tall parts must hold a tight Z dimension.

Appendix D — Consolidated references

Source list for the data values, methodologies, and references cited throughout the volume. Per the editorial principle in §1.3, the citation hierarchy is manufacturer filament TDS first, resin manufacturer TDS second, peer-reviewed literature and independent testing third, with vendor marketing relegated to the bottom of the source stack. Where a stable canonical location exists, the URL is given below with the date it was last checked (May 2026). Filament technical datasheets are versioned and their document paths change with vendor website updates; for those, the manufacturer's official domain is given as the stable entry point rather than a deep link that will rot, and the reader should expect the live TDS to supersede any figure quoted here. This list does not claim per-claim version provenance: individual numeric values were drawn from whichever TDS revision was current during preparation, and that revision is not always recoverable. Treat the volume's figures as starting points to be confirmed against current vendor data, exactly as §1.3 and the Preface state.

D.1 Independent testing datasets MyTechFun comparative filament test database. An independently compiled dataset of tensile, layer-adhesion, and thermal measurements for a large number of filaments, tested on a single reference machine with a uniform test geometry. It is a useful cross-brand sanity check on manufacturers' TDS-published values. The database is the property of its author and is distributed to the project's Patreon supporters; its specific measured values are not reproduced in this volume. Readers who want the underlying numbers should obtain them directly from the MyTechFun project (mytechfun.com and the associated Patreon), under that project's own terms. §13.7 and §14.11 discuss, in general terms, the patterns such independent testing reveals — datasheet stiffness overstating printed-part performance, and heat figures diverging by test method — without citing any of the database's figures.

Prosumer-printer community troubleshooting analysis. The author's statistical analysis of ~910 community-reported troubleshooting threads on a single prosumer printer model, classified into 15 issue categories. Cited in the polymer chapters as the empirical basis for the relative frequency of failure modes (VFA, layer adhesion loss, bed adhesion, warp) across polymer families. Method and classifier are documented in the author's published write-up; see the revision note in D.5 for where errata and supporting material are tracked.

Califlower Mk2 dimensional calibration methodology. A multi-feature XY-shrinkage test geometry published on community model repositories alongside the calibration methodology used throughout this volume. Provides both external and internal dimensional checks for shrinkage compensation tuning. The model and accompanying method notes are published on the author's Printables profile (accessed May 2026).

Table D.1 — Manufacturer TDS sources by filament family. Each manufacturer publishes current technical datasheets on its official domain (e.g. bambulab.com, prusa3d.com, polymaker.com, 3dxtech.com, fiberlogy.com, spectrumfilaments.com, basf-forward-am.com, eastman.com); those domains are the stable entry point and were the live source checked May 2026. Deep links to individual TDS PDFs are deliberately not listed because vendors revise document paths frequently — but, unlike a prior revision of this appendix, the official domains above are given so the source is locatable. Where a datasheet states a version, the volume cites it inline (for example Table 14.6 cites the Bambu Lab PPA-CF TDS V1.0); where it does not, the figure should be treated as the revision current at the time of writing and reconfirmed against the live TDS.

Indoor air and emissions. ANSI/CAN/UL 2904, "Standard Method for Testing and Assessing Particle and Chemical Emissions from 3D Printers" (first edition, 2019) — UL Standards & Engagement, ulse.org; background and the underlying UL Chemical Safety / Georgia Tech research at chemicalinsights.ul.org. NIOSH, "Approaches to Safe 3D Printing: A Guide for Makerspace Users, Schools, Libraries, and Small Businesses," DHHS (NIOSH) Publication No. 2024-103, at cdc.gov/niosh/docs/2024-103/. NIOSH Health Hazard Evaluation Report 2017-0059-3291, "Evaluation of 3-D printer emissions and personal exposures at a manufacturing facility," at cdc.gov/niosh/hhe/ (reports/pdfs/2017-0059-3291.pdf). All accessed May 2026.

Food contact and biocompatibility. U.S. FDA food-contact regulations under 21 CFR Part 177 (polymer-specific subparts), via ecfr.gov; NSF/ANSI 51 (food-equipment materials) and NSF/ANSI/CAN 61 (drinking-water system components), via nsf.org. FDA, "Technical Considerations for Additive Manufactured Medical Devices — Guidance for Industry and Food and Drug Administration Staff" (finalized 5 December 2017; docket FDA-2016-D-1210), via fda.gov. ISO 10993-1, "Biological evaluation of medical devices — Part 1: Evaluation and testing within a risk management process," via iso.org. All accessed May 2026. As §8.9 and §19.4 stress, food-contact and biocompatibility certifications attach to a resin grade or a cleared device and validated process — not to filament generically.

D.5 Editorial scope and revision context This volume was compiled May 2026, with brand surveys current to early 2026 and calibration profiles measured on the author's prosumer hardware in 2025–2026. The polymer-chemistry foundations and process-physics principles will remain accurate; the brand surveys, price ranges, and specific product availability will drift and should be verified against current vendor data for procurement decisions. Errata and updates are tracked on the author's GitHub repository alongside the supporting calibration methodology and the associated slicer calibration-edition fork.
