摘要:

     激光成形技術(shù)能夠?qū)崿F(xiàn)生物醫(yī)用材料、人造肢體及醫(yī)用植入體的個(gè)性化設(shè)計(jì)和生產(chǎn)，并且具有很少的工序環(huán)節(jié)和很短的加工周期，因此在生物醫(yī)用材料的制備領(lǐng)域具有重大應(yīng)用價(jià)值。目前適合于生物醫(yī)用材料制備的激光成形技術(shù)主要有立體光刻（SL），分層實(shí)體制造（LOM），選擇性激光燒結(jié)/熔化（SLS/SLM）和激光立體成形（LSF）技術(shù)。基于各種激光成形制備技術(shù)的原理和特點(diǎn)，綜述了激光成形制備生物醫(yī)用材料的研究進(jìn)展和應(yīng)用現(xiàn)狀，認(rèn)為中國(guó)在激光成形的各個(gè)單項(xiàng)技術(shù)領(lǐng)域同發(fā)達(dá)國(guó)家的差別并不大，但綜合集成和產(chǎn)業(yè)化的差距卻非常大。因此，形成包含完整產(chǎn)業(yè)鏈的產(chǎn)學(xué)研創(chuàng)新聯(lián)盟是激光成形技術(shù)在中國(guó)生物醫(yī)用材料領(lǐng)域科技發(fā)展和產(chǎn)業(yè)振興的重要途徑。先進(jìn)的裝備技術(shù)是任何一種技術(shù)充分發(fā)展和應(yīng)用的必要基礎(chǔ)，也是我國(guó)生物醫(yī)用材料產(chǎn)業(yè)落后于發(fā)達(dá)國(guó)家的關(guān)鍵環(huán)節(jié)之一。因此，迫切需要建立適用于醫(yī)用植入體制造的專(zhuān)用激光立體成形制備系統(tǒng)，形成具有市場(chǎng)化前景、自主知識(shí)產(chǎn)權(quán)的產(chǎn)品工程化技術(shù)和工藝流程，并建立相應(yīng)的技術(shù)標(biāo)準(zhǔn)體系，以顯著提升我國(guó)生物醫(yī)用材料及醫(yī)用植入體的技術(shù)水平，促進(jìn)我國(guó)醫(yī)用植入及組織工程領(lǐng)域的整體發(fā)展。

Abstract:

     Laser fabrication can realize individual design and production of biomedical materials, artificial limbs, and medical implants with fewer working procedures and shorter processing cycles, thus having an important potentiality in preparation of biomedical materials. Nowadays, the main laser fabrication techniques suitable for preparing biomedical materials include stereolithography (SL), laminated object manufacturing (LOM), selective laser sintering/melting (SLS/SLM), and laser solid forming (LSF). Current research progress and application of laser fabrication techniques on preparing biomedical materials were reviewed based on their fabrication principle and characteristics. It is pointed out that the significant gap in laser fabrication technology between China and the developed countries lies only in the overall technical integration and industrialization, yet not in any individual technical field. An important way to promote the research and industrial revitalization of laser fabrication techniques in China biomedical material field is to build a production-study-research innovation alliance comprised of a complete set of industrial chain. In the meantime, advanced equipment technology is the basis for development and application of any techniques, and it is also one of the key fields in Chinese biomedical materials industry that lag behind those in the developed countries.
