Printing of white plastic parts using Selective Laser Sintering technology
Maximum dimensions: 190 x 230 x 315 mm
Material: polyamide PA2200 (PA12)

The process:

• The geometry is based on 3D CAD model, imported into the system in STL-model.
• This is additive process, i.e. the part is made by adding material, layer by layer.
• Plastic powder is used; the particles are sintered by laser to form a dense part.
• The parts are fully functional and can be used for prototypes and small series production.

Selective laser sintering system Formiga P100.

The process is described in the figure 1. The building of the parts takes place in the building chamber. The chamber has elevated temperature and shielding gas is used (nitrogen). At the beginning the insulation layer of powder is applied onto the building platform. Then, a building layer (0,1 mm) of the material is applied by the recoater. Then the cross section of the part is sintered by the laser beam. New layer of fresh powder is applied and the sintering process is repeated until the building of the part is completed. 

Figure 1. Laser sintering working principle schematic.

At the end of the process the parts produced are surrounded and supported by loose powder, so building of support structures is not needed. It is also possible to produce many parts together. The main advantage is large design freedom – almost no geometry limitations exist. For example it is possible to produce moving joints and combine multiple parts together for compact design solution.

The advantages of the technology are as follows:

• Almost no geometry limits
• Thin walled structures can be manufactured (minimum wall thickness is 0,5 mm)
• The wall thickness may vary in large extent in different areas of the part
• Process is highly automated, no special tools are needed
• Fast process

Example: Technology is especially suited for manufacturing electronic equipment casings

Example: Geometrical limitation are almost non-existent

Example: Moving parts can be manufactured without the need for assembly

Expertise work and engineering services are mostly needed to identify the causes of failure or the processes that led to failure or prevent failure. Expertise work is not only carried out to resolve disagreements between the parties but also in situations where the manufacturer or user of the product is investigating any process or characteristic related to the product:

• the fracture / wear of a particular item;
• premature failure of re-conditioned machine part e.g. breakage / wear;
• the causes for rejected parts during production;
• the suitability / characteristics of the used material 

 
When accepting and ordering expertise work,  the following must be considered:

•  the expert's assessment is only for the part/component provided by the customer;
• the tests carried out must remain within the competence of the  laboratory;
• all questions cannot be answered unambiguously.

The losses resulting from wear in life cycle cost of equipment may be tremendous. In some industries recycling of wear parts and consumables may compose up to 40% of life cycle costs. Decreasing of these costs is possible using wear resistant composites – cemented carbides and cermets. These materials are ceramic-metal composites produced using powder metallurgy (PM) technology – compaction of green compacts followed by hot consolidation (sintering).
Cermets are composite materials composed of hard ceramic (prevalently carbides or carbonitrides) and metal (usually Co, Ni, Fe) materials. Cemented carbides (hardmetals) are ceramic-metal composite materials on basis of tungsten carbide (WC).

Cemented carbides with cobalt binder WC-Co have been attained the most attention. These composites are used for production of machining tools and other wear resistant products with high hardness and strength. Cermets, usually based on titanium carbide (TiC) or titanium carbonitride (TiCxNy) are used instead of cemented carbides in specific application fields due to their superior wear and corrosion properties.

Opportunities of the PM laboratory
Products and prototypes from cemented carbides and cermets for companies are produced using technological opportunities of the PM laboratory of Tallinn University of Technology:

• equipment for comminution and mixing of starting powders (ball mills, attritors etc.)
• presses for powder compaction;
• equipment for hot consolidation: vacuum and sinter/HIP furnaces, equipment for hot isostatic pressing (HIP) and spark plasma sintering (SPS).

Application examples

• wearing parts of metal forming tools (punches and dies)
• wearing parts of mining equipment (cutters)
• wearing parts of disintegrators and other milling equipment
• studs of automobile tyres etc.

The materials chemical composition and microstructural analysis are mostly needed in the following cases:

• for the assessment of material conformity
• for identification of the material during expertise work
• to determine the material designation of the broken product
• to develop part/product heat treatment technology.

It is advisable to assess the conformity of the material whenever there is a suspicion that the purchased material does not meet the specified chemical composition rquirements. The additional costs occurring due to use of non-conforming material exceeds the costs to determine the materials designation forehand significantly. Damage may be due to the non-machinability of the material (deformability, weldability, cutting performance, heat transferability, heat-transferability, etc.), the product does not meet the required mechanical properties (low strength, brittleness, low wear resistance, low impact-resistant, etc.).

Structural analysis of the material (micro- and macrostructure) also allows to assess the conformity of the material (eg, the proportion of ferrite, the grain size, non-metallic inclusions, porosity, liquidation, cracks, etc.) and allows us to assess the quality of the heat treatment (structure, depth of hardening, decarburisation depth) and it is possible to find out the technological operations performed on the part/product (forging, rolling, etc.).

When new material is to be purchased as an additional cost when purchasing the wrong material, indirect costs are associated as higher workloads, failed delivery times, loss of customer confidence, will also be added.

Metallide ja nende sulamite struktuurianalüüs nimetatakse metallograafiaks. Metallograafia on üldjoontes purustav kontroll, mille käigus lõigatekse uuritavast detailist proovitükk (suurusjärgus 5...40 mm) ja see lihvitakse, poleeritakse ning seejärel söövitatakse. Peale poleerimist tulevad töödeldud pinnal esile mittemetallsed lisandid ja tühimikud ning praod (makrostruktuur, suurendus <50x). Poleerpinnalt on võimalik mõõta mikrokõvadust ja näha on ka pinded. Söövitamise tulemusel tuleb esile materjali mikrostruktuur (terade ja faasidevahelised piirjooned, suurendus >50 x). 
Mikrostruktuuri või makrostruktuuri analüüs lõpeb enamasti arvutis foto töötlusega ja sinna selgitavate tekstide ja jooniste lisamisega, mis ühtlasi jääb ka dokumenteeritud materjaliks ning esitatakse lisadena.

Mikrostruktuuri analüüsitakse järgmistel eesmärkidel:

• Materjali mikrostruktuur (tera suurus, kuju, struktuuris esinevad faasid). Lisaks on mikrolihvilt võimalik uurida ka erinevate struktuuriosade mikrokõvadust ja keemilist koostist elektronmikroskoobis.
• Mikrostruktuuri põhjal on võimalik anda mõningatel juhtudel hinnang materjali keemilise koostise kohta.
• Materjali pinna analüüs (pinded, termokeemiline töötlus, süsiniku väljapõlemine, teradevaheline korrosioon).

Materjalis olevad defektid:

• mittemetalsed lisandid (räbu, grafiit),
• poorsus (gaasi ja kahanemispoorid),
• likvatsioon (erinevate osakeste kuhjumine, näiteks karbiidide kuhjumine terade vahele termotöötluse tulemusel),

Makroanalüüsil jääb vaatevälja suurem ala ja silm eristab üksikute suurelt nähtavate detailide asemel terviklikku pilti. Makroanalüüsi võib teostada detaililt töötlemata (näiteks murdepinna analüüs) või siis tehakse sarnaselt mikrolihvile makrolihv. Makrolihv on enamasti rohkem söövitatud, kuid ei pruugi erineda mikrolihvist.

Makrostruktuuri uuringutega on võimalik määrata järgmisi asjaolusid:
Materjali pinna analüüs (suuremad pinded, termokeemiline töötlus, süsiniku väljapõlemine, teradevaheline korrosioon).

Materjalis olevad suuremad defektid:

• mittemetalsed lisandid (räbu, grafiit);
• poorsus (gaasi ja kahanemispoorid);
• makropraod (termilisest töötlemisest, väsimusest);
• tekstuuri (terade orentatsiooni, mis on tingitud enamasti plastsest deformatsioonist)

Murdepinna analüüs:

• purunemise iseloom (habras-, väsimuspurunemine);
• purunemispõhjuste selgitamine.

Mikro- või makrolihvi valmistamisel sisaldab teenus järgmisi operatsioone: 

• võimalikku katsekeha tükeldamist;
• võimalikku vormi pressimist (kas 25, 30 või 50 mm vormi);
• lihvimist/poleerimist;
• vajadusel söövitamist. 

Edasine struktuuri analüüs toimub mikrstruktuuri uuringutena mikroskoobis või siis murdepinna uurimine palja silmaga või binokulaarse mikroskoobiga ning järelduste fikseerimine fotodele koos seletustega.

Materjali keemiline koostise määramine on kõige enam vajalik järgmistel juhtudel:

• margivastavuse hindamise jaoks,
• ekspertiisides materjali tuvastamiseks,
• purunenud toote materjali määramiseks.

Materjali margivastavuse kontrolli on soovitatav läbi viia alati kui on kahtlus, et ostetud või ostetav materjal ei vasta margiga määratud keemilisele koostisele. Tarnitud vale materjal poolt tekitatud lisakulutused ületavad reeglina materjali margivastavuse määramiseks tehtavad kulutused mitmekordselt. Kahju võib seisneda materjali mitte töödeldavuses (deformeeritavus, keevitatavus, lõiketöödeldavus, kuumtsingitavus, termotöödeldavus jne), toode ei vasta nõutud mehaanilistele omadusetele (tugevus väike, külmaga muutub hapraks, kulub kiiresti, ei kannata löökoormusi jne).
Kui vale materjali ostu korral tuleb osta lisakulutusena uus materjal, siis enamasti lisanduvad ka kaudsed tootmiskulud, mis väljenduvad suuremates töömahtudes, hilinenud tarneaegades, klientide usaldusväärsuse languses/kaotuses, hilisemates vaidlustes materjali müüa ja toote tellijaga.

Keemilise koostise määramiseks teostatakse järgmised operatsioonid:

• valitakse õige baas (Fe, Cu või Al) ja seejärel õige programm, mis määrab ka elementide arvu ja piirmäärad (vt. tabelit pdf);
• seade kalibreeritakse;
• kalibreeritud seadme näitu kontrollitakse MBH analytical LTD poolt sertifitseeritud katsekehadega;
• katsekeha pind puhastatakse ja töödeldakse vajaliku pinnakareduseni;
• määratakse katsetatava materjali keemiline koostis massiprotsentides.

Vastavalt keemilisele koostisele materjali margi määramine on lisatasu eest teostatav operatsioon.

Keemilise koostise määrame toimub spectraalanalüsaatoril ( Atomic Emission Spektroscopy by Spark AES: sädelahendusel toimuv aatomite emissioonspektroskoopia) Spectrolab M, millel on kolm baasi (sulami põhielementi): Fe, Cu ja Al. Keemilist koostise määramise võimalused on piiratud määratavate elementide piirväärtusetega (vt. tabelit pdf).

Analüüsi teostamiseks on vajalik proovikeha gabariit- mõõtudega 50x10x20 mm, ümarmaterjalide puhul minimaalse diameetriga 14 mm ja materjali paksusega vähemalt 2 mm. Maksimaalsed gabariitmõõdud on 200x50x100 mm.

Erinevate TalTech laboritega koostöös on võimalik meil lahendada keemilise analüüsi määramisel erinevaid spetsiifilisi probleeme kasutades elektronmikroskoopi ning konsulteerides keemikutega.

Mechanical testing is part of the material characterization (determining the designation) in addition to chemical composition and structural analysis. Tests are carried out according to standards using suitable test pieces. The exact testing method is agreed with customer.

Mechanical testing can be divided into three groups namely strength, toughness and hardness testing.

As a result of strength tests, the ultimate and yield strength and elongation to fracture are determined and the toughness test determines the ability of the material to withstand impact or resistance to crack growth. The hardness test evaluates, in particular, the heat treatment quality and also the wear resistance of the material

We have experienced team and calibrated equipment.

Kõvadus on materjali võime vastu panna kohalikule plastsele deformatsioonile, kui tema pinda tungib suurema kõvadusega keha.
Kuna kõvaduskatse kahjustab katseobjekti pinda vähe ning mõõtmine toimub suhteliselt kiiresti, kasutatakse kõvadust sageli materjali mehaaniliste omaduste hindamiseks ning kvaliteedi kontrolliks. Näiteks kasutatakse kõvaduskatset metallisulamite termotöötluse hindamisel ning oletatavate (kahjulike) karastusstruktuuride kindlakstegemiseks keevisõmbluse ümbruses. Materjali kõvaduse määramiseks kasutatakse järgmisi meetodeid ning vastavaid kõvadusmõõtureid.

Brinelli meetod (ISO 6506-1; DIN 50351)
Rockwelli meetod (EVS EN 6508-1; DIN 50103; GOST 8064-79)
Vickersi meetod (ISO 6507; EN 1043-1; DIN 50133; GOST 2999-75)
Universaalmeetod (DIN 50359-1, EN ISO 14577-1).

Õhukeste pinnete või materjali erinevate struktuuriosade kõvaduse määramiseks kasutatakse Vickersi mikrokõvaduse skaalat. Kasutatavad koormused on  väikesed (10…200 g).

Kõvaduse määramiseks kasutatav meetod sõltub järgmistest asjaoludest:

• katsekeha kõvadus (meetodi piirangud)
• katsekeha paksus
• katsekeha suurus
• pinna seisund ja kuju.

Suurte ja raskete katseobjektide, mille toimetamine laborisse on raske või võimatu, kõvadust on võimalik määrata kasutades portatiivset kõvadusmõõturit DORERNST.
