Metal 3D printing

Nuper nos fecit demonstrationem metallum3D printingEt perficitur ipsum feliciter ita metallum3D printing? Quid commoda incommoda?

Metallum 3D printing est additive vestibulum technology qui aedificat tres dimensiva obiecti per addendo metallum materiae iacuit per iacuit. Hic est detailed introductio ad metallum 3D printing:

Technical principle
Selective laser sintering (SLS) : The use of high energy laser beams to selectively melt and sinter metal powders, heating the powder material to a temperature slightly below its melting point, so that metallurgical bonds between powder particles are formed, thereby building the object layer per iacuit. In printing processus, uniformis iacuit metallum pulveris primum posuit in printing platform, deinde laser trabem lustrat pulveris secundum crucem figuram obiecti, ita ut liquefit Expleto layer printing, platform guttae quaedam distantia, et expandit novum iacuit pulveris, repetere supra processus usque totum obiectum typis.
Selectivam laser liquefacing (SLM) Similar to SLS, sed altior laser industria, metallum pulveris potest omnino liquefactum formare denses structurae, et vires et melioris mechanica proprietatibus potest adeptus et vires et meliorem mechanica altiori vel etiam excedunt partes producitur traditum vestibulum elit. Est idoneam ad vestibulum partes in aerospace, medicinae apparatu et alia agrorum, quae requirere princeps praecisione et perficientur.
Electron trabem liquescens (EBM): usum electronic trabes ut an industria fons ad conflandum metallum pulveres. Electron trabem habet characteres summus industria density et altum scanning celeritate, quod potest cito solvito metallum pulveris et amplio printing efficientiam. Printing in vacuo environment potest vitare reactionem ex metallum materiae cum oxygeni in printing processus, quod est idoneam ad printing Titanium mixistae, nickel, secundum allimis et alia metallum materiae sensitivo ad oxygeni et alia metallum materiae sensitivo ad oxygeni et alias metallum materiae sensitivo ad oxygeni, saepe in aerospace, medicinae apparatu et alias in Aerospace, Medical Equipment et Altissimo -end agros.
Metal material extrusion (ME) : Material extrusion based manufacturing method, through the extrusion head to extrude the metal material in the form of silk or paste, and at the same time to heat and cure, so as to achieve layer by layer accumulation molding. Comparari laser liquescens technology, in investment sumptus est inferior, magis flexibile et convenient, praesertim idoneam ad mane progressionem in officio amet et industriae elit.
Communis materiae
Titanium mixe: habet commoda princeps viribus, humilis densitas, bonum corrosio resistentia et biocompatibility, late in aerospace, medicinae apparatu, automotive et aliis agris, ut aircraft vestibulum.
Steel immaculatam: habet bonum corrosio resistentia, mechanica proprietatibus et dispensando proprietatibus, relative humilis sumptus, est unus de communiter materials in metallum 3D printing, adhibetur ad artifices in Metal 3D, utendum est ad artificialium in mechanica, et sic est.
Aluminium Alloy, humilis density, princeps vires, bonum scelerisque conductivity, idoneam ad vestibulum partis cum princeps pondus requisita, ut automobile engine cylindro obstructionum, aerospace structural partes, etc.
Nickel, secundum Alloy, cum optimum summus temperatus viribus, corrosio resistentia et oxidatio resistentia, quod saepe in armorum officinis et tortor components ut aircraft engines et Gas Turbines.
commodum
Maximum Design Freedom: et facultatem ad consequi fabricare complexu figuras et structuris, ut cancellos structuras, topologically optimized structuras, quae sunt difficile et impossibile ad consequi in traditional vestibulum processus, providet maiora initium, quae sunt difficile, providet maior est in proscriptio Et potest producere levius, summus perficientur partes.
Redigendum numerum partium multiplex partes potest integrated in totum, reducendo nexu et ecclesiam processus inter partes, amplio productio efficientiam, reducere costs, sed etiam amplio reliability et stabilitatem in productum.
Prototyping celeri potest producere ex prototypum a uber in brevi tempore, celeritas sursum in productum progressionem cycle, redigendum investigationis et development costs, et auxilio conatibus adducere products ad forum citius.
Lorem productio: Secundum singula necessitatibus customers, unique products potest esse in occursum speciali requisitis diversis customers, idoneam medicinae implantatorum, jewelry et aliis domiciliis agris.
Limitatio
Pervenit superficiem species: et superficiem asperitas typis metallum partes est relative altum, et post-curatio est requiritur, ut molere, ut amplio perficies, augendae productio sumptus et tempus.
Internal defects: there may be internal defects such as pores, unfused particles, and incomplete fusion during the printing process, which affect the mechanical properties of the parts, especially in the application of high load and cyclic load, it is necessary to reduce the occurrence Internum defectus optimizing printing processus parametri et adoptare oportet post-processus modi.
Material Limitations: etsi genus metallum 3D printing materiae praesto sunt augendae, sunt tamen quaedam materialis limitations comparari cum traditional vestibulum modi, et altus-perficientur metallum materiae sunt magis difficile ad procer et sumptus est altior.
Cost issues: The cost of metal 3D printing equipment and materials is relatively high and the printing speed is slow, which is not as cost-effective as traditional manufacturing processes for large-scale production, and is currently mainly suitable for small batch, customized production et areas cum princeps productum perficientur et qualitas requisita.
Technical Complexity: Metal 3D Printing involves complexu processus parametri et processum imperium, quod requirit professional operators et technica firmamentum, et requirit princeps technica gradu et experientia operators.
PRAEGRESSUS
Aerospace, usus est fabricare Aero-engine laminis, Turbine discs, cornu structurae, satellite partes, etc, quod potest reducere pondus partium, amplio cibus efficientiam, redigendum et reliability ex partium.
Automobile: Manufacture Automobile Engine Cylindri obstructionum, transmission testa, Levighteight structural partes, etc, ad consequi leve consilio automobiles, amplio fuel et perficientur.
Medical: De productione medicinae cogitationes, artificialis articulis, dentalis orthotics, implantable medicinae cogitationes, etc., secundum singulas differentias aegros medicinae cogitationes et curatio meliorem.
Moliaretur vestibulum, vestibulum iniectio formam, mori mittens fingit, etc., breviare ad fusum artificem vestibulum cycle, reducere costs, amplio accurate et multiplicitate fingunt.
Electronics: Manufacturing Radiators, conchas, circuitus tabulas electronic apparatu, etc., ad consequi integrated vestibulum complexu structurae, amplio perficientur et calor dissipationem effectum electronic apparatu.
Jewelry: Secundum ad excogitatoris scriptor creativity et mos necessitatibus, a varietate unicum jewelry potest fabricari ad amplio productio efficientiam et productum personalization.
