  • threads larger than M12 or 1/2”€³ can be successfully printed with 0.2-mm layers, while smaller threads should be printed with thinner layers.
  • PETG has a tensile strength of around 7,250 psi and a high elongation at break (>20%), making
    it stronger andĀ less brittleĀ than both PLA and ABS. Additionally, PETG has a glass transition temperature of around 80Ā°C, which allows it to maintain its properties at moderately high temperatures

    OK ! IT’s FAR From a PERFECT WORLD . . .at least for THE “mugs” out there !

     

My “consensus”
>
2023

and Still just My Opinion ONLY !

Listen ! > be prepared to ”learn the “hardway”

Prove Me wrong !
. . .

& with “evolution

THAT IS
THE
Science !

  • Low Cost printers  (<1000) > still very “speculative”
  • OEMs treat the marker as “guinea pigs” to troubleshoot > debug their proto-types after 20 years > they are gettng better with more R&D and less “hype” as the “mug” market has since “dried up”
  • many “scammers”
  • OK for kindergarten kids perhaps and pseudo s’ware ‘Template’ models for making stuff they
    can probably already get from “trash n’Treasure anyway . . . for little cost  > a “convenience” factor perhaps but at huge “time-wasting “time & effort”
  • Commercial are good even for Ulem (PEEK Clone) but expensive
    Heated Bed;
    Compromises
  • AutoCad is hopeless fort many ! learning curve and “contrived “ambiguity and redundancy
    in THAT S’ware industry TOO !
     
  • 3D Scanners are improving but 10 to 20micron resolution from $10k)+ for example for decent work you really need >
  • heated bed 90C
  • Oven encloser  > uniform 180 - 250C > for PEEK maybe ?
  • linear bearings
  • High Quality Stepper motors
  • auto bed-levelling and decent adhesion for intital layer strengt
  • safety issues re overnight sloe jobs > camera built-in alar
  • no Filament > auto-resume ( re expected Govt caused PowerOut “scams”earning cueve and NOR for the dumbed-down “ or without necessary “long-term tinkering” experience
    exotic fiamets > toxic fumes > require “effective” HEPA Filtter exhaust re OH&S
     
  • HighTemp ( > 280-350C ), non-abrasive filament jet
  • a slow frustrating for anything really worthwhile ?( > a toy still )
    > still slow and expensive 1000’s & part price cost>benefit still required
    Another ~10 years evolution but for “protoypes” ONLY EVER and Never as good as Injection Moulding re cost and strength > if U justify the large Qtys
  • “deluded “Hobby” Shops inevitably leads to “blatant scamming” and All “faked > pseudo Science”associated with AL ( > most High Tech “initiatives” these days !

RESIN Printers promising ? BUT

Resin OEM still REFUSE ( & illegally ! > Be-A-Ware ! ) To disclose proprietary  Formulations
re resin / Solvent vapor etc re BOTH
OH&S abu also foy getting ANY required certification for Medicalpharmaceutical product use

 

Strength of finished part ? a compromise at best ! > “ Be-A-Ware! “

  • Highly dependant on build-Quality compronses 3D Printer OEMS > cheap parts
    ( & often 3D printed ) ;  low cost Power Supplies )
    rewquires sturdy mounting and “ robust “ printer Frame > rails etc
  • Light-weight Print-head
  • jet ID & Filament diameter ( most are 1.75mm )
  • Layer ( Step) height
  • NO In-fill ( square, triangular etc )
  • Wall Layer thickness
  • filament type of course PLA is high strength but useless outside re UV Moisture deterioration over weeks ) Nylon, stabilised PC are OK
  • some require pre-drying of the filament before printing ( eg Nylon
  • exotic mixes or compositer (glass/graphite) filaments add to strengthossiblw with
    end product “touch-up” rethreading etc
  • Threads (nuts&bolts) are near impossible with re-drilling > threading touch-up,
  • due to gross or marginal “warping shrinkage of the “final” printed product
  • For “critical” APPS TEST Your FINAL 3d Printed PRODUCT before “usage”

an “apt” analogy” might be ( my “observation”
~90% of “ALL PCs” over `45years in the hands of kids & house”wives” (gender neutral Or Not ! ) have
found PCs absolutely redundant beyond PCs have been largely relegated to the “dump” or “locked-in-the-cupboard” AND far beyond the simple need of a “2-bob” calculator “for adding up their grocery bills “
for example despite Microsoft etc hype > decades of built-in obsolescence perhaps? and trillion $ cost waste” !
Business YES ! > a completely different matter but still a “gross” OVERKILL !

OR threats of “AI - Artificial Intelligence” TOO Late” already embedded in the “heads” of MOST OF
“The media” and MOST “politicians & “entrenched  bureaucrats who obviously enable and exploit the “contrived” situation
