_{Table A.1 — Ther­mal en­ve­lope across the poly­mer fam­i­lies cov­ered in this vol­ume. Con­tin­u­ous ser­vice tem­per­a­ture is derived from RTI/HDT data and creep behavior per polymer — there is no reliable T-offset formula — and is not the ab­so­lute upper limit, which is clos­er to Tg 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 Tm. (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 ~190–230 °C at 0.45 MPa for annealed and process-tuned grades (vendor figures up to ~240 °C depending on test method; see Table 14.5) — so the fil­a­ment datasheet should be read with the test basis in mind. The continuous-service figures reflect RTI-class data adjusted for grade: the low-crystallinity printability-modified unfilled grades are creep-limited near their ~80 °C Tg, while CF grades retain stiffness well above it; the 180–230 °C figures sometimes quoted for PPA-CF are short-term or annealed HDT values, not continuous service.}

_{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 elongation and notched-impact figures vary widely with resin grade, test method (ISO 180 Izod vs ISO 179 Charpy), specimen basis, and print ori­en­ta­tion; the ~8–24 kJ/m² impact range spans ven­dor TDS val­ues near the low end and in­de­pen­dent­ly mea­sured flat-print­ed spec­i­mens near the high end. Treat these as ori­en­ta­tion- and method-de­pen­dent, not single allowables.}

_{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 has been run marginally in 65 °C Tier 3 active chambers, 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. (e) Mainstream PCTG grades specify 250–270 °C (Spectrum, Fiberlogy) up to 260–280 °C (Tritan-class 3D-Fuel) — above the Tier 1 nozzle ceiling, so Tier 2 hotend capability is required, though no enclosure.}

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 45–65 °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.

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.

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. Values that drive material selection should be tied back to the relevant table note or current TDS, including method, specimen type, print orientation, dry/wet conditioning, and anneal state. 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 its creator's (Vector3D's) Print­a­bles pro­file (ac­cessed May 2026).

D.2 Man­u­fac­tur­er tech­ni­cal datasheets Fil­a­ment TDS data is cited from the man­u­fac­tur­ers' pub­lished doc­u­ments on their of­fi­cial web­sites and dis­trib­u­tor por­tals. The prin­ci­pal man­u­fac­tur­er ref­er­ence points used across the vol­ume:

_{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.}

D.3 Resin man­u­fac­tur­er ref­er­ence data Base-poly­mer TDS data is cited from the resin pro­duc­ers where the fil­a­ment TDS is silent on a prop­er­ty of in­ter­est and the fil­a­ment is clear­ly built on a doc­u­ment­ed resin grade. The prin­ci­pal resin pro­duc­ers ref­er­enced, with their of­fi­cial ma­te­ri­al-data do­mains (ac­cessed May 2026):

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.
