    Fusion 360 vs Blender: Pick Your First CAD Tool

    Both articles compare the two main free modeling paths hobbyists use for 3D printing: parametric CAD in Fusion 360 for precise functional parts, and mesh sculpting in Blender for organic shapes. In this episode you'll learn: Fusion 360 offers a free personal-use license for hobbyists that includes most features needed for 3D printing, though with limits versus the paid subscription. Prusa Research offers a structured online course in 3D modeling with Autodesk Fusion aimed at complete beginners. For 3D printing, most Fusion 360 users only touch a subset of tools: sketch, extrude, fillet, and chamfer. Blender is fully free and works with a polygonal mesh of thousands to millions of triangles and quads that you shape like digital clay. Blender navigation uses middle mouse button to rotate, Shift plus middle button to pan, and scroll to zoom, with three core modes: Object, Edit, and Sculpt.

    Prusa XL vs Voron 2.4: Buy the Toolchanger or Build It

    Both articles tackle the advanced maker's fork in the road for flagship CoreXY machines: pay for a finished 5-tool toolchanger (Prusa XL) or build an open-source printer yourself (Voron 2.4). In this episode you'll learn: The Original Prusa XL is a CoreXY printer with a 360x360x360 mm build volume and a toolchanger holding up to five independent print heads, each with its own nozzle, filament, and temperature. Each XL tool is built on the Nextruder extruder and parks in a docking station at the edge of the machine; the carriage sets down one head and mechanically couples with the next in a few seconds. Because each XL tool stays permanently heated and ready, color changes swap the whole head instead of purging one shared nozzle, cutting the waste of a purge tower that can exceed the size of the part itself. The Voron 2.4 is an open-source CoreXY printer released in May 2020 by the Voron Design team founded by Maks Zolin, with public documentation, CAD, STL parts, and firmware; you build it from a bill of materials or a third-party kit. The Voron 2.4 uses a flying gantry raised by four independently driven Z motors that self-levels against the bed, plus the community StealthBurner direct-drive toolhead, and ships fully enclosed.

    Under 15000 CZK in 2026: A1 mini as Your First Printer

    Both articles show that sub-15000 CZK FDM printers now ship with full auto-calibration, and the Bambu A1 mini is the cheapest gateway into color-capable, hands-off printing for a first-time buyer. In this episode you'll learn: The Bambu Lab A1 mini base version runs around 299 dollars, and the Combo with AMS lite is around 459 dollars. The A1 mini build volume is 180 x 180 x 180 mm; the full-size A1 offers a 256 mm print area. Bambu Lab introduced the A series in late 2023, targeting everyday consumers and beginners rather than prosumers. The A1 mini arrives pre-assembled and pre-leveled, and the manufacturer says it is ready for a first print in roughly 20 minutes. The enclosed Creality K1C typically sits in the 11000 to 13000 CZK range depending on the current deal.

    Picking Engineering Filaments for Parts That Must Hold Up

    Both articles help you match an engineering filament (ABS, ASA, Nylon, PC) to the actual load a functional part will face, and avoid the failures that show up when you guess wrong. In this episode you'll learn: ABS and ASA share print parameters: nozzle around 240 to 260°C, heated bed at 90 to 110°C, and an enclosed chamber to suppress warping. ASA was developed to resist sunlight, while ABS in direct sun becomes brittle, yellows, and degrades at the surface, so ASA is the pick for garden, facade, or car window parts. Enclosed machines like the Bambu Lab X1C or H2S handle these materials more reliably because a stable temperature around the part is critical for ABS and PC. For load-bearing parts PLA often is not enough; PETG, ABS, or carbon fiber composites step in, and abrasive variants need a hardened nozzle. A broken microSD slot on cheap control boards is fixable with a microSD-to-full-size-SD extension adapter mounted in a printed holder, for example on an 8mm frame like the Anet A8.

    Engineering Filament Tuning: Stringing and Flow Rate

    Getting clean, dimensionally accurate prints in PETG, ABS, ASA and nylon requires attacking moisture and flow rate together, not just copying PLA recipes. In this episode you'll learn: ABS and ASA print at roughly 240°C to 260°C, keeping the melt liquid longer after retraction and worsening stringing. PETG, nylon, PA-CF, ABS and ASA are hygroscopic; absorbed water flashes to steam in the nozzle and sputters material during travel moves. In PrusaSlicer the flow control is called extrusion multiplier; in Bambu Studio and OrcaSlicer it is called flow ratio. Total flow equals the firmware flow multiplier times the slicer extrusion multiplier, and M221 overrides the firmware value at runtime. Bambu Lab documentation notes PLA flows easily, ABS and nylon are denser, PETG is sticky, TPU is elastic and viscous, and composite filaments are abrasive.

    Nylon vs Polycarbonate: When PLA and PETG Stop Cutting It

    When desktop FDM hobbyists outgrow PLA and PETG, nylon and polycarbonate are the next step for heat-resistant, load-bearing functional parts, but only with proper drying and hardware. In this episode you'll learn: PA6 reaches around 70 MPa tensile strength while PA12 sits at 45 to 55 MPa, with PA12 absorbing only about 1.5% moisture by weight versus up to 9% for PA6. Polycarbonate delivers 55 to 75 MPa tensile strength and notched impact toughness of 600 to 850 J/m, an order of magnitude above most FDM materials. Pure polycarbonate has a glass transition around 145°C, and Prusament PC Blend is rated for use up to 113°C per the Prusament data sheet. Prusament PC Blend prints at a nozzle temperature of around 275°C, and Polymaker requires an actively heated chamber for PC-FR, PC-ABS, and PC-PBT variants. Nylon and PC are both highly hygroscopic; without drying, prints show cracking, milky surfaces, and degraded mechanical properties within hours of room exposure.

    ABS vs ASA: Printing Car Parts That Survive Summer Heat

    Automotive heat reveals which 3D printed materials actually survive. PLA softens near 60°C and fails in a hot car, while ABS handles interior heat and ASA handles exterior sun and UV. In this episode you'll learn: ABS has a glass transition around 105°C and parts work long-term at roughly 80 to 90°C, while PLA starts softening at 50 to 60°C. ABS density ranges from 0.9 to 1.53 g/cm3 with a median of 1.07 g/cm3, and thermal conductivity sits around 0.1 W/(m K). ASA replaces ABS's butadiene with an acrylate elastomer, which resists UV photo-oxidation that yellows and embrittles ABS outdoors. ASA tensile strength is about 33 MPa and Izod impact strength around 321 J/m, comparable to ABS (30 to 40 MPa, 200 to 400 J/m). ASA Heat Deflection Temperature reaches up to 93°C per Prusament data, in the same band as ABS (80 to 98°C).

    Spring Recap: TPU, Slicers, Printers and Reader Q&A

    Both articles wrap up the first month at printara3d.cz, consolidating practical lessons on materials, slicers, printer ecosystems and the most common reader questions. In this episode you'll learn: TPU 95A is among the hardest and most widely available variants, while TPU 85A or 75A offer higher flexibility for shock absorption and ergonomic parts. TPU typically prints at 20 to 40 mm/s with retraction of 0.5 to 1 mm, a 0.4 mm nozzle, 220 to 240 degrees C nozzle and 40 to 50 degrees C bed. The slicer market consolidated around three players: OrcaSlicer, Bambu Studio and PrusaSlicer, with OrcaSlicer becoming the standard for advanced users. PETG-CF contains 10 to 20 percent carbon fibers by weight, costs two to three times standard PETG and requires a hardened nozzle. First month at printara3d.cz covered PETG composites (week 1), Bambu Lab AMS on X1C and H2S (week 2), and ABS/ASA warping (week 3).
